Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
hi there, I am Cam. Can I get your first name please?On your transfer case, it is actually a NV246 transfer case and there is no prevision to add a PTO. There is a redesigned clip that installs on the back housing to prevent the pump wear hole in the back housing.
The case half may be the same. The big difference between the 246 and 261 is the 261 does not have the automatic 4wd setting, you get 4hi, 4lo and 2 hi. For the clip, you cannot weld it on, the clip is steel, pump ear aluminum and back case half is magnesium alloy. Anyway the design does not require any form of attachment as it stays in place on its own.
For your brake, that likely means the shoes in the rear rotors are out of adjustment. You have to get the rotors off to adjust the shoes, there is no access to adjust them.
