Has been doing this for more than 2 1/2 years and 55,000 miles. Haven't driven it much since starting as wasn't a primary ride. Now have to start running to work. Have had two different shops tell me it's left rear axle bearing and another one tell me pinion bearing. No play or metal found in system. Any ideas or experiences anyone can share before I tear into?
Change both axel bearings at the same time. The pinion bearing can be tested by slowly turning the drive shaft by hand and listening for any rough spots. It could be a carrier bearing or a bad U joint too. Isolate it by dropping the drive shaft and turning the pinion yoke by hand. If there is a problem, you'll be able it feel it. Then look at the drive shaft for worn carrier bearing and U joints.

you need to check you universal joints usualy the one on the rear axel is the first to go. i recomend to put bolth in at the same time. the new ones will be greasable so dont forget to give them a little every oil change

The first problem that I see is.....
You got screwed, the rear brake shoes and the parking brake shoes and the same thing. The parking brake uses your back brake pads to set the brake.
Sorry man

Hi joelalthomas, if they replaced your brakes and you never even made it home they had better warranty the work and as for the "it was a common problem on 2002-2004 trucks" well check for Chevy recalls as this is a safety issue that would have been corrected at no expense to the vehicle owner, do a little more research my friend and let me know what happens, I will check around a little as well in the meantime I would find a new garage.Do not pay any more as you said your brakes worked fine until they worked on it good luck to you As for your 4x4 did you look at the left side when you did the right side? and were they bled off properly? you can visually check to see if the calipers are functioning

your description sounds like the gears inside the the same differential you just replaced.

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.
Testimonial: "You were absolutely correct. Low coolant level. Put in some 50/50 and we're nice and toasty now, but need to find out why coolant was so low. Thanks."
