1999 2wd rcsb 4/6 drop

Has anyone had issues with breaking u-joints after installing the kit. My pinion angle is spot on, but after a test drive it vibrates like crazy. Thinking maybe my u-bolts arnt holding the rear end in place. Some pics or advice would be great

 

How is your driveshaft length?

 

The kit came with plates that have offset holes that move the rearend to makeup the new driveshaft length. However I could have them backwards. I'm assuming the rear needs to be moved forward when lowering.

 

I think you've got it backwards

 

Correct

 

Thanks guys

 

I checked my brackets today and I have them setup to push the rear slightly back from the transmission. Just like the instructions say. Could it be possible that my u-bolts aren't holding the rear from twisting? I'm stomped

 

Anyone?

 

1 or 2 piece driveshaft? If 2, did you relocate the carrier bearing?

 

1 piece driveshaft. Going to have the driveshaft looked at to make sure it's balanced
