SOURCE: CLAKING SOUND COMING FROM ENGINE

Sounds like you either burned a piston or broke a piston rod. Also you might have bent a valve. The bad news is that these repairs are very expensive. Goodluck and PEACE

SOURCE: rear door speakers don't work w/ aftermarket radio in 94 suburban

You need to attach the blue wire on the stereo harness to the blue and white wire on the car adapter harness. they installed a small amplifier to power the rear door speakers and unless you connect those two wires then the speakers will not work.

SOURCE: 1994 Chevy suburban 4x4 had rear end done and when

pinion depth was not set properly when the rear end was done, take it back where you had it done. Probably by now the ring and pinion have suffered unrepairable damage and will have to be replaced again.
