I dropped my 99 Silverado RCSB with a Belltech 2/4. I used springs in the front and shackles and hangers in the back. The shocks are Belltech NitroDrops. After I got everything put back together and took it for a spin, at around 5-20 MPH I get this high pitched chirp/squeak. It sounds like u-joints to me, but is it more than likely a pinion issue? How do I fix this? I am on my way to have a badass truck, and this is kind of annoying and takes away from the work that was put into it.

thanks

Oh yeah, all new rear brakes. New sway bar end links, front end is completely greased. All the little stuff was taken care of during the install.

 

have you measured your pinion angle

 

I have not. Is there a way to do it without buying a "angle finder"?

 

help?

 

you need to shim your axle... probably 4-6 degrees will work.... they go between you axle and leaf springs...

 

I just got off the phone with stylintrucks and they suggested 3degree shims. I bought em, so hopefully they work. I am scared to drive the truck as it sits now.

 

I just got done pulling the helper spring out and putting my 3degree shims in(fat side forward) and the truck still squeaks. Could it be my u-joints? I'm getting kinda frustrated here.

 

could be, did you make sure the caps are tight on the joints? I actually did that, and got under that and torqued them down.

 

I havent checked the caps, I can do that. I just ordered some 6degree shims, because the 3degree still had the pinion pointing upwards.

Also of note, when I put the truck in reverse, I get this loud pop/click as well. It doesnt do it when i go to any other gear.

 

I would say u joint. No sure what having the pinion off would sound like.
