Did you clean the rear gears? If so, how?Changed out both diffs of a 2011 GMC Yukon with AWD and the 6.2 liter engine.
When so tight, easy to cause damage when removing bolts? Necessary to retighten with torque wrench, or just regular wrench?All bolts and the plug came out well after a shot of Liquid Wrench. I recommend using a 1/2 inch drive ratchet wrench, as a smaller drive ratchet wrench doesn’t give enough leverage and feels scary tight.
Did this come with new bolts? Or reuse old ones? RTV alone sufficient?I used a new AC Delco rubber gasket from Rock Auto but the old one might have sufficed.
Did you clean the rear gears? If so, how?
I cleaned the magnets and the cover only.
When so tight, easy to cause damage when removing bolts? Necessary to retighten with torque wrench, or just regular wrench?
I sprayed the bolts with liquid wrench and slowly used a 1/2 inch drive ratchet wrench to slowly apply torque to the first bolt until it broke free. Once I knew how much torque it would take, the others were quicker. No bolts snapped. I torqued the bolts to 25 ft lbs using a 1/2 “ drive torque wrench with the new gasket.
Did this come with new bolts? Or reuse old ones? RTV alone sufficient? I reused the old bolts. The AC Delco gasket is a rubber compound and does not require RTV.
