I HAVE A 2002 BRAVADA AND MY COMPRESSOR MAKES A LOUD NOISE FINIALLY BLEW THE FUSE. I REPLACED THE FUSE AND SAME NOISE COMES ON AND CAR IS NOT LIFTING, GMC DLR TOLD ME NO I CANT REPLACE IT WITH SHOCKS OR STRUTS, I LIKE THE IDEA OF PUTTING ON COIL SPRINGS IS THERE A DIFFERANCE BETWEEN THEM AND STRUTS AND SHOCKS?

I have a 2002 Bravada w/air suspension. When the compressor is loud it is bad. I bought a new one for less than $300 off the net but after 6 months it is not inflating the rear even though it runs briefly after start-up. It is most likely the compressor check valve. The Compressor Service Kit costs about $25 at the dealership. My rear air springs went bad (right side first) with cracked rubber and leaking. The right side was always lower when it would inflate and would leak until the whole rear was down. New air springs are about $85 w/o shipping @ GMPartsDirect.com. Also, the sensor can go bad but my buddy who works on Bravada/Envoy said this is usually NOT the problem. Compressors go bad after a few years and the air spring rubber deteriorates causing leakage. If the air springs leak, the compressor runs alot more and wears out faster. I'm not a certified mechanic, but have replaced the compressor myself and it took about 2 hours. As for the Compressor Service Kit instructions- you can search "Bravada Letting You Down?" on the net and a tech gives full instructions on how to service the compressor. He states that the compressor check valve sticks and it will not build pressure to inflate the rear of the vehicle.

no, just replaced mine, springs are independent of shocks and struts

SOURCE: struct replacement. Do I need to use a spring compressor?

any strut you need to compress the spring before you crack that top center bolt its potentially dangerous dummies been hospitalized from flying springs get a good compress not super squeezed get the resistance off the nut just a half inch gap then take off spring load spring and when you load look at the bottom of the spring has a cut on the coil seat it right the coil sits the cut end on the bottom seat ....

SOURCE: Grinding noise on 2002 Olds Bravada

Try making tight turns to the right and then to the left. see if the grinding noise comes and goes. It could be your C/V joint and they need to be replaced. The noise will only come when your making the tight turns, you don't have to go fast. Walking speed will do and you can hear it with the window open or someone walking beside the Bravada. Good luck and keep me posted. Be glad to help.
