Question about 2002 GMC Envoy

Open Question

2003 GMC Envoy: It makes a loud whining noise through acceleration above 20 mph from the rear center of the vehicle. It started out in the 60's and has made its way down to the 20's. Mechanic says the rear differential needs to be replaced. Too much damage to be rebuilt. True?

Sounds Like Pinion Bearings , But Carrier Bearings Should Be Replaced (In My Opinion) as they Could Be Contaminated

This rear end needs to be replaced or re-built. The gears and or bearings are worn/shot. May be able to get a complete rear end from a Junk yard for much less, one in good condition. Good Luck

What is the drive cycle for a 2003 Nissan Sentra SE?


Take extra caution while performing dirve cycles on public roadways. Drive cycles can be difficult to follow under normal driving conditions. Begin by: - Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on. - Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. - Hold at a steady speed of 55 mph for three minutes. - Decelerate (coast down) to 20 mph without braking or depressing the clutch. - Accelerate back to 55 to 60 mph at ¾ throttle. - Hold at a steady speed of 55 to 60 mph for five minutes. - Decelerate (coast down) to a stop without braking. If all other emissions systems are functioning properly, completing the drive cycle above will set the "readiness flags" required to pass the smog check. It will not hurt to perform the drive cycle 2 or 3 times before the smog test.

I HAVE A 2003 GMC ENVOY XL SLE.I WENT OVER A HUMP AND IMMEDIATELY HEARD A LOUD WHINING NOISE. TURNED IN PARKINGLOT AND WENT TO BACK UP AND IT WOULDNT BACK UP. IT WILL DRIVE FORWARD...STILL WITH WHINING...


First thing to check are the transmission fluid lines, make sure they are not crushed or leaking. Also do a good visual inspection of the underside of the truck for any obvious damage.

2006 GMC Envoy has 2 problems. I thought the alternator was going bad because of some battery problems. Pulled it out and had it tested. Nothing wrong with it. The biggest problem is a loud whine when...


The whine could be a pulley, start the engine, raise the hood, and then rev the engine to see if you can duplicate the noise. It could be a weak belt, or a bad bearing in either the alternator, or a pulley when the engine is under a load. Check your fuel lines and the schrader valve on the fuel rail to ensure they are good, and stop the leak. Usually a fuel leak on an engine will dissipate to quickly and you can never find it, so be thankful that you did.
