First off. when going about 1 to 5 mph the rear end makes the truck shimmy back and forth. Also when giving it gas on the highway the truck jerks to one side like the brake is on one side and it makes it pull to one side. I just put in the locker and gears so ay ideas. It is almost scarey.

 

What kind of locker do you have? Detroits and Powertrax lockers are bad for the highway lunge that you are describing. HOWEVER, it should NOT be shaking at slow speeds, and I have no idea what could be causing that.

 

Maybe a bad bearing? Or .... did you get the axles in all the way and get a good fasten on them????

 

Did you add fluid after the install? Don't laugh, I know someone who burned up a new rearend.

Don't drive it until you get the issue fixed.

 

fluid was added. I havent been able to tear it down yet.

 

who did you have do the work Alex? one of the guys at the dealership?

 

It was a buddy but now it is at the dealership

 

Let us know what they find out!

 

i did find a set of stage 2 heads and a set of yellow terra cheap. I might have to have them throw that in at the same time

 

throw them in huh....go for it. make sure the yt rockers don't raise the lift to high for the springs you have. and what size valves are in the s2 heads?
