    Anybody have some insite on where to get shims? I've called Skyjacker and they dont sell them. They only come on the spring packs.

    Im sure I can have some made at a local machine shop, but how do I know they will know how to make them correctly?
    Im not sure of the shim I need yet.
    I have an angle finder, which Im about to go use to find these angles.

    Im doing this to get my rear to 1 or 2 degrees till I can aford to have the perches moved or I till I can learn to use this welder in my garage.

    I can get steele shims from riteway spring in Tacoma, WA. I have a set of 6 degree shims on the rear of my truck. I welded them to 1in solid steele blocks. The shims and blocks ran me about $40. The set even came with a dowel to use as a spring pin.

    You should be able to pick them up at your local 4x4 shop. If not then call Stephen at Off Road Design, and he can probably fix you up! Jon

    I bought 6 degree shims from 4wheelparts and they run about $20 a pair with the center bolts. The Shims are Superlift and the bolts are Rancho. I haven't installed them yet but I do have them and if you need I can find the paper work and get you the part #'s.

    Well, I was playing with my new Blue point angle finder last night. This thing ROCKS!!!! All lift installers must have one. They are only $22 from Snap-on, has a magnet built in, just stick it on the shaft, get that angle then stick it on the u-joint's as they are vertical, get that angle then subtract the difference. Very easy to read the numbers. I now now my rear joint angles are 7 at the front of the shaft and 4 at the rear. Thus the vibrations.
    But I used the ol geometry last night, I figured I'll have to raise the t-case back up then take my angles and get the correct shim from there.
    Just need to know where to get some. Right now I have a 4 deg shim. So Im betting on about an 8 or close to it to get the rear to be 1 or 2 degrees for the CV shaft.

    Next question, would it hurt to just weld the shim to the spring perch or should I go ahead and move the perch in the future?

    I would stay away from welding the shim to the pearch! It would seam kinda overkill to do so. That is what the center pin is for! Just check your Ubolt torque from time to time and no way that shim is gonna pop out!
    Best of luck!!

    I was just thinking that a 8 to 10 degree shim would be kinda skeeeeery or debatable as far as axle wrap an all.

    Yeah, I was gonna replace the Skyjacker center bolt with a good grade 5 or 8 bolt. The one that came with the springs, doesn't have a bolt head on it. So its a pain in the ass to install and remove.

    Oh, Im gonna go with the perch move, but I need to use shims for now till I can get the perches moved. Besides I wont be doing any wheelin till I get the 4.10 gears in the rear to match the front.

    Did you say I have monkeys flying outta my butt?[​IMG]
