1991 4 x4 gmc sierra 1500 rear wheel seized

SOURCE: replace rear axel bearing on 4x4 5.3 Litre gas engine

Loosen differential cover and let oil drain. Remove cover, remove U lock from axel. Pull axel out. Remove bearing seal then bearing. Install new bearing, seal and reinstall axel. Reinstall U lock and new cover gasket. Fill with 75-90wt gear oil. Now I know that sound pretty straight forward. But there are some things to remember. The U lock can be difficult to remove sometimes. The most important thing is the seal, you will need to make sure it gets seated correctly and not torn when installing axel.

the connections near the front axle that activate the motor to engage the system aren't melted? That's a comon problem for that body style. If there good, sounds like it could be that motor itself. To figure out if it's you motor or transfercase, jack up the rear end, have a friend inside shift into 4 wheel drive, or try to, and put it in gear and apply some gas. If the front driveshaft is turning then it's something with the front end. If not, farther back in the system.

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

SOURCE: need to replace brake line from rear axle forward

Chanses are it broke behind the gas tank wear it runs along the frame rail. You don't need a diagram to fix that, just unhook it at both ends and break it off or cut it off buy the tank and take the pieces with you to a auto parts store and they will match it up with new line, just take a tape measure and measure from the rear axel to the front block or perportioning valve, and don't worry about the piece behind the tank, just run the new line alongside the old one behind the tank unless you want to pull the tank out.
