I have a question about GM differentials.
You guys are the best mechanics I know.
This one is from a 91 S-10 2wheel drive.
Open diff 300,000 miles.
the axle seals were shot so the brakes were full of grease, so I replaced the entire assembly, bearings and even the backing plates.
So of course I had to pull the diff cover to pull the axles.
I decided to do the Pinion seal too.
I measured the rotating torque with my inch pound bending beam and it was undetectable! the needle didn't move.
When I rotated the pinion there was a slight clunk from the backlash between the pinion and the ring gear.
SO....
Putting it back together.
Should I follow the factory recommendation of 3-5 inch lbs greater than the starting torque?
Is the minor clunk any concern?
This is in a street rod so it's not going to be putting one another 100,000 miles any time soon!
Thanks guys
