'99 GMC Sierra 1500 rear end broke

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.

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.
