Default I give up

I installed my Moser 12-bolt, Dennys Nitro DS, and BMR LCA's about 3K miles ago. For the past 1.5K miles there has been a "chunking" noise whenever i'm turning sharp on uneven pavement. Happens every time I pull into my driveway. Not to mention the car just doesn't seem to handle right. Yesteday I checked the torque on all the bolts, they are all tight. I also changed the diff fluid (yes I used posi additive).

I might take it to the dealership and see what they say. Even though its aftermarket stuff, they might be able to figure it out. If that fails I might have to make a trip to my nearest LS1 Speed Shop (LS1 Speed prolly). If anyone else has this problem or knows what i'm talking about, please post.

Did you buy the rearend assembled or did you put it together yourself?

I didn't set up the gears. I put in the axles, axle bearings, etc.

Hey Alex, I know you've prolly heard this before but lat time I changed gears I put in this aftermarket posi additve that claims to be as good as GM. Mine clunked like crazy.

Tore my hair out for weeks...even reset my gears to a looser backlash lettin more fluid in...did'nt help.

Decided to take it apart one more time. Store was out of the additive so I had to go to GM. Not a single noise...cept tires fryin <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Good luck, Stu
