Would anyone be interested in my doing a build thread of this?

I'm using a set of Toyota FJ60 axles modified to position the diffs in the same location as the LR diffs, and the WMS to WMS 59" instead of LR 55", might go 54" on rear.

I'm on the Big Island HI, and getting LR axle upgrade parts is expensive, plus I already have a set of FJ60 axles and diffs. I've got all the brackets and flanges cut off and cleaned up, ready to have the ends machined to make make them the correct width including a 4Plus housing sleeve and accept the knuckle balls and disc brake flanges. The pinion and castor angles will be set when welding on the Ruffstuff spring perches.

The front gets RCV 30 spline chromoly axles/CVs and chromoly hub gears.
FJ60 vented rotors, Toyota V6 Mini Truck calipers (4- 42mm pistons),
Sixshooter knuckles & ARP studs.
Ruffstuff knuckle ball gussets, spring perches, Mini Truck truss (modified to fit), shock mounts, rear diff cover (cut off sheet metal cover, welding on extra layer to flange, drilling and tapping to accept Ruffstuff diff cover).
Marlin 25mm steering pin upgrade kit.
4x4 Labs high steer from behind & GM 1 ton tie rod ends.
Rebuilt FJ60 steering box, with crush tubes and extra plating on frame rails for steering box. Aisin hubs. Probably forgetting something. Lol

The rear axle, gets RCV 30 spline chromoly axles with drive flanges pressed on.
Ruffstuff disc brake-FF flange, spring perches, mini truck truss, shock mounts.
LC front spindles and hubs, LC vented rotors, FJ60 Calibers (2- 42mm & 2-38mm) pistons. Outer part of housing sleeved (more on that later).

LC diffs, driveshafts get LC flange to diffs and LR flange to TC.
Land Cruiser, 5.5x16 split rims widened to 6.5" & 255/85-16 tires.

This gives strong set of axles, with 4" wider WMS to WMS, 4 wheel disc brakes, that are relatively inexpensive and readily available parts, and I have most of the components. Other than axles, diffs & steering everything will be Land Rover.

It's a 72' SIII SWB that is getting a new Series IIA type bulkhead from West Lakes All Wheel Drive, he is putting together a kit for me to build, I already have new foot wells, door pillars and making a jig from original bulkhead.

Fitting higher output & pressure PS pump for PS and for Vans Hydro brake booster. This eliminates the vacuum pump and bulky brake vacuum booster.

Putting in a 300Tdi, (rebuilding) with a new, Turner Engineering's ported and flowed head, moved 4" forward with new motor mounts, to keep the Series front.
Rebuilding the R380 Stumpy gearbox (basically just a R380 with a 4" shorter bell housing, and a few extra bits).
Ashcroft adapter kit to mate the Series TC (rebuilding) to the Stumpy R380. This lets me keep the Series front and the TC stays in the same position so I don't need to shorten the already short rear prop-shaft.

Building new chassis rails and cross members 1 & 4 out of 10 gauge,/3.5mm steel. The weight difference between 2.5mm (what Richards Chassis builds them out of) and 3.5mm for these is less than 20lbs, and the rear crossmember out of .188"/3/16", with the same shape & profile.
Building in mounts for a bolt in winch tray to fit a winch under floorboards and between frame rails, controlled with remote, air free spool actuator, opening in rear cross member for winch line and fairlead to mount.

From Richards Chassis, getting 1 Ton dumb irons, Australian Military SWB rear spring hangers
2" taller (longer?) to match the 1 Ton dumb irons, Military length extended shackles, under flywheel crossmember 2, scalloped (for driveshaft clearance) military bolt on under gearbox crossmember 3 and the 6 outriggers (all of the Richards Chassis parts are 2.5mm), to mount left side under seat, aux fuel tank.
I've got a fuel filler neck assembly so it will match the right side.

The front suspension gets Rocky Mountain 3 leaf Parabolic rear springs (one leaf can be removed if wanted).
Extending the front chassis horns 3.25" and and using Ruffstuff 2" dia through the frame rails shackle hanger mounts with 1.5" bushings, moved aft the accordingly and Ruffstuff offset shackles, spring perches, spring under U-bolt protecting cradle U-bolt plates and U-bolts.
Mounting the 3 leaf rear springs, flipped, to keep front axle in same location.
Ford shock towers bolted on with through the frame crush tubes welded in, for extended travel shocks.

Rear gets Rocky Mountain 3 leaf Parabolic springs.
Ruffstuff shackle hangers, shackles, spring perch, spring under U-bolt protecting cradle U-bolt plates and U-bolts .
The spring perch has an additional spring pin hole drilled 1" to the rear and using a 1/2" thick axle relocating plate to be able to move the rear axle 2" to the rear and have 90" WB. If ever wanted the axle can be moved 1" forward or put in stock location,


Building a bumper and brush bar that basically looks like the 110 Camel Trophy ones, except the bumper and the lower brush bar won't have the bump out in the center for the winch, since the Series front is set back.
Have the hard top with the tropical roof panel and sides.
Using Exmoor Deep Weave tilt and sticks in Sand.
Body and wheel color will be Bronze Green.

Setting it up with dogclutch hydraulic pump for front and rear hydraulic winches later.
Most likely going with Red-Winches' Challenger winches, they weigh less than half the Mile Marker winches, Will decide later.

Every bolt, unbolted every rivet is being drilled out, steel parts sand blasted, aluminum parts soda or bead to bare metal blasted to bare meal, galvanized pieces re-galvanized, all others primed, painted and Raptor liner between the steel and aluminum parts before riveting back together. Basically building everything to new or better tolerances. Oh, did I mention I'm a little OCD? Lol
But for me the fun is in the details, whether designing how things go together or the finish work. I look at the whole build as a system and hopefully everything works together and it doesn't look bodged up. I'm really working to (hopefully) make everything look like it was built this way, not chopped and modded.

I trying to keep the look as LR as possible, I think the FJ axles wont be too noticeable, I mean I hope they don't jump out when giving a casual look, of course on closer inspection they won't look LR, (they have 6 instead of 5 lug nuts!) but over all I want to keep the basic look and feel of a Series IIA as much as possible.

Cheers, Allen

It's a Land Rover Series III with a Series IIA bulkhead and narrowed Toyota FJ60 axles and diffs, with the rear axle converted to FF and disc brakes, the rest is LR Series.

I won't have a lot to post till end of Aug. as I'll be getting more components & materials then. I have lots of parts and pieces and things disassembled. Over the next month or so will be working on the axle housings and media blasting everything.

Thought I'd start out with the axle housings, since they are being modified a bit differently than usual. I hope I don't give to much information and to many pics, let me know if I'm going overboard! :) I'll try to briefly explain the reasons for building something a certain way, it may not be a good reason, but at least what it is attempting to accomplish.

The rear axle housing is an 84' FJ60. This is the semi floater flange and I used a angle grinder to cut it through to the housing:


Then pounded it them off and that leaves this machined surface that is parallel to the one on the other side. Then after wire wheeling and going over it with a flap disc. Will sand blast it after everything is welded on and before priming with Rust Bullet and painting with Rust Bullet Blackshell.

Aloha brother. I'm over on Oahu. I'd love to check out your build next time I'm on the BI. Sounds like a fantastic project and I'm definitely going to be following.

I've always thought about Yota or Dana axles on a stateside project just for ease of access to parts and upgrades.

I'm not very good at the techie stuff, as will become apparent..

On the long side, the machined surface is being extended inward, to give a uniform size and surface. But since we're removing some metal, machining a short piece of tubing to fit over the machined area an inch or so past where the disc/FF flange will mount, so both welds be offset a bit. I ordered the disc/FF flange for 3.5" housing, and machining the OD of tubing to 3.5" for the flange to fit.

The reason for this is the long side needs to be shortened (don't remember the exact amount at moment) about 2.5"-3",nd the short side extended about 2.5", so the diff/pinion is in the same position as originally.

On the short side, machining the part of the sleeve to match the machined surface on end of housing, and leaving the part of the sleeve that extends the housing thicker on the ID. The OD of the sleeve, machined to 3.5" to fit the disc/FF flange.

This is a pic of Ruff Stuff's axle housing, but it shows how the disc/FF flange fits on end of housing and disc calibers and front spindle mount. I haven't figured out how to write after I upload the pics or to write under each pic to describe the pic. Some coaching please? :)

Looks awesome. I fly private inner island quite a bit. Used to work at Kona from time to time at Paradise Helicopters but no longer. If you ever need something from Oahu, you know where to find me and I can track it down and help out. We island boys gotta stick together on the shipping wars! lol

FYI, there are no less than three SIII and at least one SII in and around the Kailua area over here where I live.

For the pictures and typing, just post one picture and upload it. You will see it show up as an image code on your post area. You can then type above that photo and leave the image code stream directly under your typing. then insert another picture and hit upload. The code will show up and just move (cut and paste) it to where you want on the post.

Example attached.

To seal the rear diff oil, the hub/spindle bearings will be ran with grease like in the front. To keep the diff oil and hub/spindle grease from mingling and the diff oil from going AWOL, the rear spindle is machined to fit a Marlin Crawler Ecoseal. This is not my I idea, a gentleman on ih8mud came up with it and has tested it.

The Ecoseal is made to handle some misalignment and stay sealed. When ordering the axles from RCV, they machine a proper diameter area on shafts and polish it. The amount of metal removed from the spindle is very minimal and in that part it has lots of material around it also, but I am going to use Chromoly spindles on the rear, to gain a bit more strength on the rear ones, like the fella on Mud did. The rear spindles don't use the brass bushing like the front.

That's basically it for the rear axle, other than the Ruff Stuff mini truck truss, spring perches, shock mounts & diff guard. But that give me, a Full Floating, disc braked, rear axle that fits under the Series chassis like it is supposed to, with 3"-4" wider WMS to WMS. This same modification could be used for other LC applications, by using either FJ60 or FJ40 axle housings and make a straight forward way to get a FF and disc brake rear end.

The trouble with with cutting off the flanges and trying to fit the disc/FF flange to the LC housing is, it's not actually round and getting them aligned is diffouclt. But this way, there are factory machined surfaces to work from.

Ah cool, thanks! I hear you on the shipping! lol I got an order LR from YMR Metal Solutions in the U.K. that was in three packages, one was 60" long and they weighed 73lbs, for $153, and it got here in 6 days to my door to door. Thought that was amazing!

Yeah, its ridiculous man. I have five OEM Disco 3 17" wheels coming via UPS from Scotland for $100 US shipping which is a killer deal. I order some control arms from the mainland and pay $125 on shipping, 3 times less weight and size and $25 more in cost...hahaha

I order occasionally from Australia as well and the dollar goes a long way down there and shipping is awesome. Amazon Prime is my best friend here, if I can't find it there, its gonna cost me bigtime.....lol

The front FJ60 housing started looking like this:
canvaszzz.jpg

Then ended up looking like this, with the sheet metal diff cover cut off and face ground smooth. adding a .125" ring on the face where the diff cover was, because the front face is thinner than the rear housing where diff cover bolts too. So when the diff face is drilled and tapped for the Ruff Stuff diff cover, it will have the same thickness/strength as the rear one.

Here you can see the factory machined area where the end of the knuckle ball slides in, same on both ends and their the same ID and parallel with each other and give us a place to index from on the lathe. After indexing from these two machined surfaces, will machine a inch or so of the outside of the housing on the very end. That gives us a place to index from on the outside of the housing, so we can deepen the inside machined surface a few inches. Then when we shorten the ends of the housing the factory machined surfaces are extended just deep enough to for the knuckle ball on one end and the sleeve on the other end.

canvas112.jpg

Here is the sleeve that goes on the short side. The knuckle ball is a scrap one that just shown for visualization purposes.

fff.jpgccc.jpgccdd.jpg

At first I was going to use a FJ40 front housing I have, but decided to use the FJ60 housing and when moving the diff/pinion to the right 1.5" to put the diff/pinion in the correct position, I won't need to use the sleeve because the long side is long enough that it is going to need to be shortened only an inch or so for correct fit. I'll measure it up this week and see how it lays out. The only real difference is not using the sleeve and not needing to machining the short side at all. It would save $50 and the cost to machine the short side, so nothing major.

The rust you see there is flash rust, two days ago the whole thing was shinny. It's getting oiled till I can sandblast it later this week and then spraying a light coat of primer till the ends machined and ready to weld everything on, then I'll bead blast it to nice clean metal, after welding is finished it will be Rust bullet primed and painted.


Hopefully this makes sense. :)

Cheers, Allen
