"Piglet" My new 80 (LX 450)

[Wheelingnoob]

Thanks Kurt! As I said before, I can't believe I waited this long to get an 80! I am going to take the vin into the Lexus dealer here, and see if they can print up a history on it. I would love to know about a head gasket change etc.

I had no luck with Lexus here in Vancouver, they would only check there dealer system and not there national data base. Said it was not possible even though I worked for Toyota/Lexus for 5 years and know it is.

If your truck is from the US you will need to contact a US Lexus dealer as the systems are not linked.

p.s. Kurt is the man when it comes time for parts, got all my axle rebuild parts, TRE's and and axle parts for the HJ60 as well from him. Great fast service!

Thanks for the tips 'noob! I'll try and find a cooperative dealer south of the line... I have heard nothing but good about Kurt too.

Does anybody know if you can run 315s with heavy ome and not the slightly taller J springs? If need be, can I run Js in the front and heavies in the rear without being nose high? Mine sags to the drivers side with one year old springs. "A" spring is on drivers side according to the installer... Any thoughts?

From all the reading i have done on Mud I have seem lots of people running the 315's on the OME 2.5 heavy/Med lifts.

There was also a post from a guy that has 315's and J springs in the front and heavy (non J) in the back it seemed to sit level. Usually with the heavy front med rear you get a stink bug look (back higher than the front). A friend of mine has that in his 91 and its got a noticeable rake to the rear.

Spend some time over on Ih8mud researching it will be well worth your time.

I'm in the same boat as you but starting from stock. I want to build it once and not over and over again like past trucks. I really like the look of the 315's but the thought of re-gearing ($$$) turned me off a bit. May just go with the 285's for now and re evaluate when the time comes to replace them.

I just burned up a few hours on that muddy forum. WOW! I am in awe at the amount of wasted bandwidth! I have been a member there since 06, but I think I will stick to Expo for my 80 series info! There is probably a ton of good info there, but you have to read through pages and pages of slander to find it...

On that note, does running OME heavy springs with the 10mm OME spacers require castor correction?

Any lift beyond an inch or so will probably require castor correction. You are right about Mud, there is a lot of excess junk over there, but once you fine tune your searching skills there is a lot to be learned.

You can run 315s, but you may need to drop your bump stops to alleviate rubbing or protect your shocks if you go with a longer shock setup.

For your sag you can use a trim packer. Most 80s have the "cruiser lean" so you are not in this alone....

It's not that bad on Mud! Just search and read between the spam posts. I would correct the castor if you lift it. I drove for a few years with no correction and it's not very safe. Braking causes it to pull and weave and the rig felt like it was nervous on the highway. Not a good combo for a lifted 7000 pound rig.

Yeah its got lots of info, have not found any slander really on there. I mainly use it to see what others have done and how its worked for them.

With just the heavy OME in the front you should install the OME castor correction bushings. With the spacer as well I would look at getting the Slee caster correction bushings as they give you about 1* more than the OME.

I plan on doing the Heavy front Med or heavy rear (depending on total load on the back). I will be installing the Slee bushings I think as I'm sure I will add a spacer up front to level it a bit better. May even try the J springs in the front and heavy's in the back.

 

[redthies]

I don't know for sure, mine may have the castor correction kit already. I am trying to decide whether to go j on the front and heavies in the rear or just put a trimpacker on the one side to level the front side to side.

 

[Wheelingnoob]

Well you already have the lift might as well use it, trim packers are easy. Quite a few people have a problem with the lean and use the trim packers to correct that. With the lift you have now you should be able to fit 315's with out much problem.

Easy to see if you have castor correction bushings, look were the arm connects to the front axle and if there OME they are yellow. I think Slee's are a dark blue.

What's it like to drive? When you are panic brake does it pull to one side and feel nervous? Mine required driver correction to keep in the lane any time i hit the brakes hard.

Food for thought...I had J's on my truck, I felt like they were too soft, and I swapped them out for 3" Comps. If you are planning on your truck being a 'wheeler' then the J's will be probably just what you want. If you want it for overland travel (heavier loads/dirt roads/moderate offroading) I would suggest a heavier rate spring. YMMV

FWIW, I have the 864's and a spacer in the rear.

It drives just fine and does nothing crazy. I took it into a local chain tire shop that does full mechanical work for their "free" inspection. They did find a couple of things, notably, the passenger front spindle lock washer is missing its tab for the keyway and it will need front brake pads soon. For this and swaybar bushings they want over $900... Ummmm, no. But at least I know what an hour and $50 in parts will be used for this weekend. Otherwise, all is tight.

Where does the average 4.5s oil pressure gauge sit at idle and at speed? The castor correction bushings go in the 2 holes at the trailing arm/axle or the one hole at trailing arm/frame mount?

Thanks guys for the input...

Two holes at the Axle. Don't know for sure on the oil pressure, but in the lower area of the gauge from what I recall when hot. I have the OME heavy springs at all four corners and it's still very soft. Gives a pretty smooth ride on the rough stuff out there. I don't wheel it though but have bumpers and stuff.

I run 315's and have j springs. Run Caster correction plates from Landtank a guy over on mud who designed them. Works pretty well. I run a ARB bullbar and winch in the front and a iron pig rear bumper with tire swingout. I do have a little stinkbug but when the truck is loaded for a trip it's level. Even stays level when I throw my little expo trailer on.
Here's a pic. Welcome to the sickness!
