Gear Mesh and Diff Question

[CdnCutlass]

So a buddy and I installed a 3.73 gear set (new) and a posi I picked up at a swap meet. I don't know if these pictures have enough detail can anyone tell me if this gear mesh looks good?

The problem I have now is that going into corners, especially right turns the rear end is making noise like something is binding or rubbing. The posi looked new (springs still had paint on them) but I don't trust it I wonder if it's no good?

What shims did you use, looks a little close to me... Did you measure the backlash?

Did you remember the friction modifier?

I used the shims out of the complete install kit I bought. The factory shims were way off. It was within spec according to the instructions of 8 to 12 thou.

I used Lucas gear oil that has a friction modifier built in.

Check to see if one of your Brake drums is rubbing the edge of the backing plate. sometimes a different carrier will relocate the axle just enough to cause a clearance issue

it's 6 - 10 thou in a 7.5. Did you install a new crush sleeve and what is your preload?

Backlash came right in at 9 thou. I installed a new crush sleeve and preload set at 25 inch pounds as per the instruction sheet.

you have all that right, for the shim on the pinion did you use the one that came with it?. The shim is normally 32 thou and once a pinion is set up in one rear end it will work in about 99% of other rear ends. I'm not saying the mesh is no good, I can't see the markings that well
