Default Gear pattern advise




Any rear diff guys out there that can help me? Backlash at .008 drive side looks close but the coast side is way off. Is this a backlash issue. These are used gears also. Thanks in advance

the compound is applied too thick/excessive and the excess is wiping over to cover the true pattern.
Yes the coast side is apparently off.

Remember to do each pattern separate, and hold tension on the ring gear while spinning the pinion. I would add a little pinion shim and rerun it to see how it changes.

backlash 8 thou, had to push my car off the rack and I could here the gears ratcheting. I'll try smaller shim.

Could the gearset possibly be shot? I installed these gears about 10 years ago and all I did was set backlash lol.
