Ok guys, I needs some help:

I am having a bad vibration under normal acceleration at about 1000-2000 RPM's and also under acceleratin at about 50 MPH. I have changed all the U-Joints and tranny mount. I shimmed the rear end so the pinion angle was up a little and it made it a little better, but that's when the vibe at 50 started. I have 2" drop shackels and when i look at my leaf springs they have a little bit of a negative arch behind the rear end housing. Any help would be geatly appreceiated.


Thanks,

Dereck

 

you need to check you carrier bearing out. negative arch. mine doesnt have that. is it soft in the rear

 

What do you mean soft in the rear? I think i may try the carrier bearing but it's like 90 bucks, and i have already spent like 200. But I really want to make it right, I am so frustrated with this, i'll do just about anything to fix it.
