Lifted Chevy Shake/Bounce Problem...??

GSLewis30 · 07-15-2009, 01:04 PM

Hi, I have a 2003 Silverado 1500 4x4 with 8'' suspension, 3'' body. I have been chasing a shake/bounce vibration in my truck for a few months now. The shake happens with 2 different sets of tires & wheels (not a tire problem). I have solved 60% of the shake from replacing the following parts.

Steering:

Idler & Pitman arms (w/ support brackets)
Custom Tie Rods w/ Heim joints
Custom Idler Pivot Assembly

CV Axles (both sides)
Rear drive shaft U-joints (both)
Inspected Both front wheel hubs (no play)

The shake acts as follows:
0-40mph - - - No Shake
40-55mph - - Bad Shake (shimmies steering wheel slightly)
55-80+mph - Shakes a little, faster pace but less violent

I am posting because I am totally out of ideas for what could be continuing to causing the shake....

Any advice would be much appreciated.....

do you have ladder bars (traction bars) in the back suspension? like these?

does your truck have a steering dampner?

drive angle may be too steep

My driveline (drive shafts) angles are actually not very steep.

Yes, I have a skyjacker dual steering stabilizer.

I do not have any kind of traction bars. Now that I think about it, on the way home from work it seemed as though the back of the truck was bouncing, I could see my tailgate hopping in my rear view mirror. Don't trac/ladder bars only helped with traction during acceleration...?

Would a rear wheel bearing cause hopping?
