Question about 2001 Pontiac Aztek

1 Answer

I have a "groaning" sound coming from my rear differential. I just got the fluid changed in the diff (using the proper fluid for the 2L) and the mechanic said that he noticed that the teeth/gears were stripped. Would this cause the groaning?

If the teeth are "stripped" as the mechanic states, all of that metal gets ground into the fluid and destroys bearings. You might be looking at getting all of the bearings replaced, aside from the gear issue.

Center differential

IF you are in constant 4wd then you will not have a centre diff unless you have an AWD. The difference is that AWD transfer cases have a centre diff that allows different road speeds between the front and rear diffs as in going over speed bumps and dips ion the road It is the same operation in the front and rear diffs that allow one wheel to go faster than the other when cornering. However in 4wd drive there is no diff action in the transfer case and both front and rear axles drive at the same speed regardless of speed bumps and dips in the road . This action produces what is known as torque wind up which results in the handling characteristics. This torque wind up places stress on all the drive line train and results in failures such as .that you describe.. This wind up is not noticeable when driving on loose surfaces slippery surfaces or in mud as it is allowed to escape when the wheels spin . If you have an AWD with diff lock capabilities then check that the diff lock is operating correctly

Rear end groan

similar problems occur with Subaru AWD systems, the problem might be the centre diff, or a rubbing mudflap, or you have put the wrong aspect ratio tyres on and the drive system is complaining.

you should only change any diff when damaged or if a different ratio is required and being a 4wd both diffs would need replacing with change of ratio, oil in the diffs should be checked regularly and oil changed every 20,000kms sooner if used in harsh condition

How do I change my rear end fluid or check it? And what kind of differential fluid would i use for a limited slip rear end?

To check the fluid there wil be a plug on the side of the Reese diff housing. Use w 3/8" ratchet to remove the plug. The fluid should be level with the button of the hole. To change the fluid first remove the fill/check plug as described above. You always want to make sure that plug comes out first so you know you can fill the diff after your done. Then place a drip pan under the read diff and remove all the bolts that hold the diff cover top the diff housing, roughly 10-12 bolts. Then carefully pry the pan away from the housing. Let the gear lube drain while you cean the gasket meterial from both the cover and the differential housing. You can either get a new gasket or you can use a good RTV type gasket maker. I prefer the higher end GREY products myself. Lay a pencil size bead around the differential. Reinstall the cover tightening the bolts to just barely snug. The RTV should just start to push out from behind the cover. Let it sit for about a half an hour and then do the final tightening. I am almost 100% positive that the rear diff talks regular 80/90 weight gear lube. Your local parts store will be able to conffirm the correct lube and the quantity, approximately 2-4 quarts depending on what size ring gear you have.

How do i change the gear oil in the rear end diff on a 85 chevy c20 3/4 ton and how many quarts will i need also it has a 14 bolt diff cover.

A stock 14 bolt rear end hold about 3 quarts. To drain the differential you will have to pull the rear cover. I jack up one end of the axzle and let drain for a while and then the other end for a while. This assures you get as much of the old fluid out as possible. After the case is drained replace the rear cover with a new gasket(I usually just use permatex ultra blue silicone). Refill the case through the fill plug located on the side of the pumpkin. Fill until the fluid starts to come back at you through the hole. Be sure to check if you have a posi or limited slip differential because you will need to add an additive to make either of these work properly. Make sure to add the additive before you top off the fluid so you don't overfill the case. I generally drive 50-100 miles and then recheck the level to make sure it is full.

I have a 2005 gmc z71 1500 4x4, the problem is that I have a chatter noise from my rear diff, it happens when I start off and turn, could it be the locker in the diff!

the noise is coming from the clutch plates in the differential, i am assuming that it is posi-trac. and not a limited slip. you can get rid of this noise by draining fluid and replacing with proper differential fluid as recommended by manufacturer (go to gmc dealer parts dept.) also ask for posi-trac additive, use two bottles, the noise will not go away instantly, you will need to drive it for at least 500 mile before you notice change,

Whenever I turning into a parking spot my car

This is caused by deterioration of the Fluid in the rear differential of the car. This occurs when the rear end is opened at its extremes at first and will progressively get worse to the point where it will make the noise all the time while driving. First the fluid in the rear end needs to be changed, and replaced with the appropriate Honda fluid (either vtm 4 fluid or dual pump fluid depending on model) if the doesnt immediatley fix the problem, there is a burnish procedure that your local honda dealer can perform for you which involves changing the fluid and cleaning the clutches inside the rear diff. Good luck!

I have a 2002 buick rendezvous when all wheel drive is engaged sometimes it makes a terrible groaning noise

The fluid in the versa trak AWD in the rear is old and needs to be drained and refilled. After you drain and refill it, make a bunch of sharp left and right hand turns, then drive it for 10 minutes. Drain and refill it for the second time and problem solved. Use only versa trak fluid available at any GM dealership. Your vehicle takes 2 bottles (16.9 oz) each change. There is a TSB at the Buick dealership on this now.
