When I put my 4.5" lift on my jeep I had to go the cheaper way and get an add a leaf with shackle. It didn't come with axle shims but I still don't have any driveline vibs. You guys still think it's necessary to put them on for future purposes?

 

you dont always need shims

what drive line do you have
stock
or aftermarket

Blank87, "If it aint broke, don't fix it"!! What I'm saying, Bro, is this. If you aren't getting any vibes the way it is. Then, don't do shims until you lift it higher or something else that causes vibes.

 

X2

but I would do one thing
and that is jack the back up by the bumper so you get full drop on the axle then turn the DS to see if it binds up at all
if it does then you need a cardon joint

 

Ya, I just didn't know if it would cause problems down the road if I didnt do something now about it. And thanks for the heads up on the DS, Ill look at that tonight.

 

if you dont have vibes and your pinion angles ok then dont bother. but if you do need them, buy steel ones! i've seen the alum. ones break many times.
