How do you set your truck up

[Rokhound]

Here is my question for you guys how did you set up your truck to receive the new rear end. Why I am asking if the truck is set up on jack stand and leans forward or back it will throw off my reading of the t-case degrees so in return it will throw off my pinion right. So how do I go about setting the truck up or am I making this harder than it is??? :oops: I am new to all this and this is my first truck I have ever built so that why I am asking.

It's all relative. As long as you know the truck isn't level (put an angle finder on the bed) and by how much, you can figure it out.

 

 

Technically you're supposed to put the weight on the axle to check it. This complicates things. And I figure nothing in life is very exact. Truth be told, I picked a number that felt good and welded mine on, then popped it under the truck and wen't "jee, that looks good".

 

 

I'm not about to say that's the best method though.

I have to admit to this as well. Factory tolerances aren't very good from any manufacturer, so as long as mine are better, I know that the truck has been improved.

I put mine under the truck jacked it up into place. Bolted up the driveshaft and then eye balled it. 3 of us agreed it looked good then welded the perches solid. We done 4-5 of them this way and no probelms yet. In fact we are gonna do up Renix Powers rear swap in a couple weeks and it will be done in the same way I am sure.

that sound great but here we go with this thought:

 

Ok guys I got the old 8.8 out from under the truck to day. I also started to set up the new 8.8 today. I have the truck set up on jack stand the front is on the 33’s and the rear is on jack stands and she is level at the frame rails and top of the truck bed rails now I don’t know if this is important but I thought I would mention it. So I got my handy dandy angle finder out and but it on the tail shaft of the t-case and it read 0 degrees what is that all about. I thought it would read differently but what ever. So I took that info and put it into the new 8.8 so the pinion on the new 8.8 is at -2 degrees and the spring perches are set at 4.5” form the ends. So I guess my question after all this BS does this sound right.

:dunno: Mine is set at 10* after all was said and done.

You have to drop the vehicle weight on the axle before you eye it up. Once it's all eyed up sitting like it would going down the road, weld er up.

On my YJ I removed the old perches put it back together with the new perches in place but loose and *hand tightened* the u bolts so I could still move the pinion up and down. Then took it off the stands and tack welded it in place and took it back out and welded them.

i think that is what i am going to do today is slide the axle back under the truck and put the wieght of the truck on it and i am going to make it look close so I just hope this is close to right so i don't eat u-joints.

I have heard that the 10* mark is the one for our trucks. I think thats what mine messured to once i done it. Thats what I'm setting my 44 at when it goes in.

yeah that is what my old 8.8 was set at and i am going to set it at 10 and call it good. More than likely i won't drive this thing to much on the road. Maybe to the trail and to work once in a while.
