Sounds like you have blown the internal heater matrix and the thermostat is not working or is blocked. you are going to need a new matrix and thermostat and a bloody good flush out of the system just in case there is something in the system means taking off the rad hoses flush them out from both ends. and doing the same to the engine. replacing the matrix as its not going to be able to fix it if its shooting water out of the vents change the thermostat check pipes for damage.

Yes you do.It would be a good idea to replace the bearing and the seal at the same time.Reason being is that 9 times out of 10 the bearing gets damaged in the proccess of being pressed off.

I wouldn't call that "normal" but, not completely unusual either. Many units will run for 300k miles without ever needing service past routine lube changes. Others will have chronic problems. It follows no real pattern.
Many times it can be traced back to the first failure which caused some slight damage from loss of lubrication and generated a bit of metal debris which throughout the entire time was never thoroughly cleaned out, instead, causing subsequent problems with other seals and components. Sometimes it is just "bad luck" that more than one less than perfect part found it's way into one item such as your differential. At the point you are at now, all this is just supposition as any evidence of the original cause has long ago disappeared.

SOURCE: bad rear axle bearing and seal on a 2000 jeep grand

Both of my rear axel seals are leaking on my 2001 Jeep Lorado. I am preparing to repair the seals thisweekend but before I do, I need to know the appropriate steps in doind so. My main concern is the ABS. Will I have to disconnect the ABS gears at all?

Likely then the tech was wrong and some damage has occurred.
(sometimes it's hard to see) Gear sets are expensive and so are bearings. Only people with the proper tools and experience should attempt a rebuild.
Most often you can find a good used unit end to end in a scrapyard for under $200. (I haven't paid more than $125 for any I have gotten lately). You can put your new axles and hub bearings on the new unit or save them for spares.
One very important thing is to exactly match the gear ratio of the one you are replacing. There should be a tag on the diff cover or you can count the ring gear teeth and divide by pinion tooth count to get that #. Some are also stamped on the edge of the ring gear as well. It takes about a day for an average person (with a helper) to remove and install one on the ground providing you have decent tools, jacks and a bit of experience. Far less time on a lift with power tools.

I have a 93 jeep grand cherokee 4x4 it is starting to hop when turning


It's the gears in the front diff. that are bad. You will need to replace those gears or the entire front solid axle.

Just replaced the rear axile, now Jeep makes a whining noise in the rear and it is boiling over the vent tube, what is going on?


If it is pushing gear oil out the vent hose,it is
over heating

The new axle bearings,etc are not going to last long

Was it rebuilt or work done on it,because quality reman
axles with the proper fluid & fluid level don't have issues.

1997 Jeep Cherokee 4.o litre, the rear diff housing is almost to hot to touch after driving for about 30 minutes. Checked oil level thats ok no other noises.


Either the vent hose is blocked

The fluid needs to be changed

Or the most likely cause, is a bad bearing
somewhere.

If you drain the oil, you will see a silvery
like mix in the gear oil from the bearing

You need to run the axle off the ground and
use a stethoscope to listen to it.
That may not give results either

Then you just strip the entire axle housing
and go thru it

I have a rubber bleeder tube hanging from forward transfer case.


If its about 1/4" inside diameter and a soft hose that attaches to the differential or axle tube, it's the vent for the diff. It is usually tucked up against the firewall near the master cylinder and is supposed to have a small vent cap (small but open shield) on it. Just tuck it back up there and secure it with a tie wrap so it doesn't drag and it will be fine.

On my 1993 Jeep Grand Cherokee the vacuum line coming off of the transfer case (quadra-trac) has come off the vacuum side (do know where it came off from) I looked around the intake, and under the air...


If it's attached to the diff housing and not to the box on the r/f axle (if you have one) it is a vent hose. Just secure it anywhere out of the way on the firewall. Don't pull it tight or when the axle moves it will fall off again!

99 Jeep Grand Cherokee rear end humming


check the differential fluid in the rear differential. if the fluid is low, add fluid and see if the noise is still there, if the fluid level is ok see if the fluid appears metallic, if it is metallic looking or excessively thick it would be a good idea to have the bearings checked out. i am in the process of rebuilding a front differential on a 98 jeep grand cherokee for the same problem. the bearings inside the differential on the carrier and pinion gear were worn out causing a humming noise. if the wear is excessive the gears might also need to be replaced
