rear axle wear

[mcwubins]

Got some questions about differential specs. My passanger side rear has been making some noise going over bumps lately and i found that i have around .036 of endplay and about .008 of up and down movement. curious if anyone knows if there is a callout in a service manual from gm about maximum wear. Thanks. Gm 10 bolt g80

There would be.  Course, for somenone to give you an actual number/range, you would need to provide some info about the truck in question.

 

You might still be able to find out the info on the way back machine for the charm.li website.

its a 2002 silverado 1500 with a g80 differential i think its a 3.73 i had read a tsb for a colorado 2015 era with a g80 that stated a max of .012 for endplay but i wasnt sure about play in the wheel bearing it self. i diddent find much online about the actual wheel bearing however.
