Hopefully someone can help me out. I have a 2001 ecsb silverado with a 4/6 drop. Flip kit and control arms. I just recently solved the vibration I had driving at speed. I had the shims in wrong. I also have the carrier bearing relocator installed. Here is my problem from a dead stop when I take off there is a vibration every time about halfway through first gear. It doesn't matter if I take off like a grandma or stick it to the floor. The best way I can describe the vibration is it feels like mild wheel hop but I know that's not it. I've had this problem before I noticed the shims were in wrong and and it still feels the same after correcting them. I have no vibration anywhere else only on take off

 

Anyone?

 

Carrier bearing angle is off.

 

How do I fix it

 

Have you checked to see if the carrier bearing bad? Just 2/4'ed my 05 ext cab and have the same thing going on. I had some vib on the highway before drop but after got the vib at take off. checked it out and the carrier was bad.

 

It's got some movement around the rubber part but the actual hard parts seem ok. How tight should it be? I can grab the drive shaft and move it some. Maybe I'm looking at it wrong.

 

Mine had a similar issue. My pinion angle was way off. I fixed it by moving the carrier bearing up and then went to 6* shims.

 

ive had the vibration in first gear ever since mine was new if you leave with the gas to the floor. but now imthinking my carrier bearing is goin out. vib from 70-78 is getting bad.

 

I need to get my driveshaft high speed balanced I guess I'll have the shop install a new carrier bearing and see what that does. My flip kit came with shims and the bracket to raise the carrier bearing so I believe all that is right...
