Just once it's like something gets in a bind forward is fine no noises the rear differential has new clutches there's a t-case saver has been in it for at least 6 to 8 weeks this jerk thing started bout 2 weeks ago thanks for the help 98 1500 4x4 quad cab oh both u-joints were done with the t-case saver

 

Is that in 4x4, or does it not matter?

 

2wd Sometimes seems worse than other times

 

Got a brake sticking? Shoes installed on the wrong side?

Recheck U-joints, make sure they are good. If all that looks ok, I would be tempted to drop the rear driveshaft, and try the test again in 4wd. (see what part of the drivetrain is actually the issue.) If the problem goes away, I would be having a look back inside the rear diff.

 

Got the friction modifier in the rear diff.?

 

I totally thought this was going to be about people that are ***holes when they back up in their trucks oopsies

 

Lol no ···Holes sorry but ill try the things y'all are telling me I did try a trick a guy at work said make circles in the truck both ways and fig 8s did that got home backed in didn't do it he told me the clutches can get dry don't see how diff is full to the plug and yes there's modifier in it 7 oz thanks for all your help keep looking if it breaks ill know what it is lol
