I would start by checking for leaks then the rear end fluid level, if no leaks and the fluid level is ok next check the u-joints, if it howls there is a problem brewing and I would not run it long howling if its just fluid and not run much filling it up should stop the noise
Check the 1994 GMC Safari's brakes. Even if the brakes are fine, dust can cause the components to create loud squeaks, rattles, and sometimes ringing noises.
will a read end from a 78 trans am fit uder my 89 GMC seirra
Yes. A rear end from a 1984 Chevy 1500 can fit in a 1988 GMC Jimmy 1500.
a 1983 1500 sierra classic rear end!!!
you would have to check the code in the glove box and call the local parts store and have them tell you what rear end goes on the Yukon and then find out what rear end the 1990 rear end is and if they are the sam gear ratio then they ar enter change able .
shoot the tires out!
Look at the lower rear end of engine
60lbs 60lbs
A companion flange is where the end of the driveshaft meets the rear end(two flat pieces that bolt together).
If you have seen metal in the fluid, the axle will need overhauled.
On my 95 Safari van, the starter is on the bottom rear end of the motor, on the passenger side. Can easily see it without jacking it up.
The howling is most likely one of the wheel bearings.
