Bearings (including main bearings) as well as rear main seal require engine removal to do it correctly. If the engine is tired, then get a different one. Otherwise your determination, financial situation and skill level will tell you what you need to do.The entire job is not difficult but takes some time and you need to make precise measurements in order to get it right. (change oil pump with bearing sets) Parts prices can be found at napa online as well as numerous other places. If you need help along the way, someone here will be happy to help!

How many hours to change a rear main seal on a 05 3.7 jeep grand cherokee


you do , me do or ASE shop do or stealership do?
in a shop they can charge flat rate or actual.
so that be different in every shop., ask em/?

depends on rust.
depends on collateral damage or root causes.
bad bearings cause bad seals.
and can even be a bad axle.
so,,, what you see is what you get in the mech. world.
if lucky a full bearing job is. 4hours, not counting driving to machine. shop
and pressing on new bearings. and other little horrors.

the fsm covers the job, but hours are just a wild guess. in most books published, and are for cars not run in the salt belt. (google that)


read the manual?
https://www.techauthority.com/en-US/Pages/Home.aspx

see all steps there.
on mine , bad bearing, took 4 hours, the 1 more wasted finding shop
with press that can do this.
on one axle the bearing inner hub was seized to the axle
so END OF LIFE on one axle.

to change just a seal, (i bet its not it, only bad)
is way less work.
3 hours? with tools.

Hello my jeep is doing a bad sound wen i roll think its the differential or seal


You really have not given enough information for me to begin to give you any real help.
What you first need to do is to determine where the sound is coming from, then take that apart and look to see what is broken or worn. Possibly you have a bad bearing at one of the wheels. One thing though. A seal never is noisy but can permit lubricant to escape from whatever it is sealing and cause that item to fail.

Rear axle bearing, need to know if tthe bearing goes first and the seal after, grand cherokee 1994


Most times the bearing fails first but a seal can fail without the bearing being bad. If you see any flaked metal in the lube behind the seal when you remove it, you can bet the bearing is failing. If you already know the bearing is bad, you know you can't get it out without damaging the seal so it really does not matter if it was good or bad since you will need to replace both..
Since the axle needs to be removed to do either job, most times it's wise to replace both the bearing and seal together so you don't need to do it over in a few weeks.

Jeep cherokee diff


Yes,it is a self contained bearing and seal together,that is off set,the bearing runs on a different part of the axle,and the seal,this way there is no leak,and the bearing rides on a smooth part of the axle,will save money,napa has the part real cheap too,ask for a pgb bearing,it is a power glide brand,I think it is like 15.00 dollars or less

Bad rear axle bearing and seal on a 2000 jeep grand


the bearing does not always have to be really bad for the seal to fail. Centrifugal force will throw axle grease outward where it gets on the rotor. That can make it feel like the rotor is out of round. If grease got on the brake pads I'd replace them and perhaps even the rotor. As far as the caliper being frozen, possible....check it out when you have it apart. You can have more than one shoe untied at the same time. Not always, but it can happen.
When replacing the seal make sure you put some grease on the lip before putting the axle back in. by doing that it won't fail from dry running before the diff lube reaches it.

What is the coolant capacity of my 1988 Jeep Cherokee?


it depends upon your engine. drive to any autoparts store where they have all of that info in a data base. know which engine you have or at least write down the VIN number in the corner of the windshield so they can look up your engine.

2000 Jeep grand cherokee 4.0 engine


HI.WELL I DON'T KNOW WHERE TO START. FRIST IF IT WAS THE FLYWHEEL IT WOULD DO IT WHEN THERE IS NO STRAIN ON THE MOTOR WHEN DRIVING. THE SAME IF YOU HAD A BAD BEARING. IF I COULD JUST HEAR IT RUNNING, IT COULD BE A BAD OIL PUMP THAT COULD CAUSE IT TO RADDLE UNTIL YOUGET THE OIL BUILT UP ENOUGH TO STOP IT. HOPE THIS HELPS. JIMBO

Leaking seal cost to fix?


which engine? if it's a 4.0L the seal is in the rear main bearing cap...I have seen people do a replacement without removing crankshaft but have never seen one done this way that worked. If leak is small, try some lucas sealer...It softens the seal and swells it a bit. Also use oil for high mile engines afterwards...that too contains a conditioner.
(cheper to try this than removing engine)
Good luck!!! If engine is not 4.0 check back with me and I'll tell you what I think. I didn't mention cost because engine removal is a lot of $$$

What has to be done to replace an oil pump on a 4.0l 1988 Jeep Cherokee?


Let me guess... you want to change the pump because the pressure is low... Unfortunately, it's likely that unless you find a ton of debris on the pickup screen, changing the pump will do nothing for you. There is a 99% probability that your engine bearings have worn to the point that you are loosing more oil going around the bearings than is acceptable. This will also eventually affect the oil wiper rings on the pistons which are not designed to wipe that much oil from the cylinder walls. Once you have removed the pan, plastigage both rod and main bearings. Likely, you will find that you need a rebuild!
