Ok, For some reason when I'm in 4 Wd especially 4 lo my 08 2dr will kind of buck while backing up. Definitely feels drive train related. I installed a coast driveshaft in the front and I'm still stock in the rear.
I have a 4" rancho lift with control arm relocation brackets in the front and the previous owner used cams in the rear.

Oh its a manual transmission too. Any ideas as to why this happens? Is just a 4 lo thing? Sure feels like something is binding. Anybody else having this issue?

Thanks

 

Wheel turned or straight?
