Lifting

It's a stupid question but it's the only one I've got now. When shimming the axles to compesate for whacked out drive line angles, do you only have to shim the rear axle or will I need to shim the front as well. I think I already know the answer is only shim the rear but I want to be sure. Also wish me luck, installing this weekend.

There are circumstances that require shimming the front. But most lifts dont' require it.

For 90% you don't need fronts because the driveshaft is 3 times as long as the rear. I believe front shims would be used in an allignment situation, irrelevant to driveshaft vibes.

Only reason to run them in the front is to correct caster if it gets out of whack.
