I have 99 Chevy silverado z71. On my truck it has 4 inch rancho shocks with 3 inch torsion keys. The keys are cranked about two inches high. It has a "Carolina Squat." Anyway, My right cv axle, the outerboot cracked and grease went all over my fender, rotor, shock etc.. So I went to my local Napa and purchased a RMFD right cv axle with a stronger outerboot. I installed it and now my truck bounces at no matter what speed Im at. I quickly parked it and need help with why its bouncing. The axle is almost at a 45 degree angle. I need it on the road monday! Please Help!

 

Welcome to the forum.

Moved your post to the Silverado section.

If your axle is truly at a 45 degree angle, I would say it's beyond the CV joint's capabilities.
