Axle shims??

[97reillyxj]

So I have a 97 jeep xj
4.5 lift in front
3" in back
Sets level because of my front bumper
I get a little on and off vibration on the highway and I know it's not the shaft because it's brand new.

I just bought a set of 4.10 axles to jump to 33" tires and ride better (d30, c 8.25) got lucky!!!
Re gear place near me wanted $1700 and forget that!

Anyway I figured while I'm switching axles why not fix the vibration while I have them out

My question is what is the correct way to find the right shims and angles?
What are the correct angle I need to have?

Thanks for the help!

Here you go. This should cover all the bases. I used an angle finder for the article, however there are free smart phone apps that are better I think

So if my t case is at 8 degrees and my axle is at 10, I need a 2 degree shim ?

Yes, if you have single u joints, not double cardan
