So I am going through the axles parts and in the process of getting a list of new parts I found out there is a bearing change around 1977 on the 3/4ton spindles. Here is the catch. I dont know what year the axle came out of.

Anyone know how I can go about finding what year of spindles I have so I get the right bearings?

Never mind I got it.

The berring change is on the HD44 to my knowledge witch has bolt on hubs. Other wise the berrings areon the same or i should say I have used the same berring on almost every 44 I built older ih stuff being the only different.

I found the differences in the spindles I was needing. I just had to find the bearing journals and mic it out. All the spindles I have are for the 78 and newer bearings. This helps because I can just figure my front end is still a 91 and not have to worry about a year for this part or a year for that part.

Main bumper section is done. I just need to weld in the spindle shafts at the bottom and then start building the swing out arms.

I finally did it, I melted thru the air hose. I had stopped cutting with plasma gun and I heard a hissing gradually getting louder. I finally melted the air line.

A quick 10 minute repair job and I was back up and running... and I only lost 5 feet of the coiled hose.

Still finishing up the end caps and I have the spindles fully welded in. Started working on the swing out arms today. This may get put on hold as I may be doing some custom tub and lid work on a customers Bantam 416 trailer.

I got the sliders back last Friday. I was one such a good pace with the rear bumper through the weekend I didnt want to break away from it.

The krinkle powder coating turned out awesome! These guys do great work! My hats off to Glendale Powder coating.

Here are the final pics to the slider project. Some one had asked about under body shots of the mounting and such so I took some of those as well.

I love the progress on the rear bumper build PMA. Now, to change the topic, I am just curious why you bolted your sliders through the bodywork, and not make a rigid construction off your frame? Are there any advantages to this system? Cheers, Chilli...

 

[PMA4x4]

ok weird I thought I responded to that. I must have forgot to hit send

Anyways... Its just another way of mounting. with it bolted to the pinch seam it is actually helping distribute the impact.

Can you use this sliders for high jack?

Can you use this sliders for high jack?

Yes but I will probably get a Jak-Jaw to help stabilize when I lift.

I decided to add a cross support from frame plate to frameplate at the last minute.

Bumper bolted on and getting the driver side swing out tacked up and verified for dimensions.

Building the sub-frame on the swing out for the accessories.

It's just a stock tire but its still needed for testing.

Everything on with room to spare.
