Topic: GM differential issue??
Hey guys I'm looking for some input on something I have never had happen before.
We tore down the diff on our Camaro (GM 10 bolt) to do a rebuild, fresh bearings, seals, etc...
When it came time to put the carrier back in the thing I could not get enough torque on one of the carrier bolts.
I typically criss cross the cap bolts and walk up the torque in steps...20 foot...40 foot...and so forth. When it was time for the final pass at 60 one of the bolts just DID NOT want to make my toque wrench click. I was pulling so damn hard my brain was telling my arm to STOP before something broke. I spun the bolt out, checked the threads, looked down in the hole, everything looked fine. I pulled both caps off, gave the bearings all a tap with a block of wood to make sure they were seated, again all was fine. So I started again, and had the same issue again. I got all 4 bolts up to 50 foot pounds, but as soon as I tried to do 60 the same bolt would not click.
At this point I decided NOT to break anything and we put the rest of it together, filled it up with sluid, and spun the wheels in the air up to about 80MPH. No issue, no noise, so at this point I think we are good.
What do you guys and gals think?? Is there a booger on the diff or the bolt that I'm not seeing?? Am I making a fuss over nothing?? Are the torques not the critical with a diff like this??
Input and ideas please!
