Case 580E 4wd 1984 front wheel bearing. - Cars & Trucks

old post, but you are first to say front. many others fail to say end of car.

is your car 4wd, as 2wd is different rules. so...??????

I toss coin land on 4WD.

2000 front wheel bearing

got it.

the 2000 year, is important.

this year is the last year, before non untized hubs.

my posts is for stock cars. only, and USA spec, cars.

other countries, evolve this in different years.



2000 (never 2001+)

fsm quotes

1. Before servicing the vehicle, refer to the Precautions section.



2. Remove or disconnect the following:
   
   
   
   
   
   • Front wheel
   
   
   
   • Brake caliper and rotor
   
   
   
   • Locking hub or hub drive flange, if equipped,(it is)
   
   
   
   • Hub grease cap, if equipped
   
   
   
   • Wheel speed sensor, if equipped (ABS)
   
   
   
   • Wheel bearing lockwasher
   
   
   
   • Wheel bearing locknut (ring) and inner washer
   
   
   
   • Wheel hub and bearing assembly (slide hammer?)
   
   
   
   • Wheel hub oil seal
   
   
   
   • Wheel bearing oil seal
   
   
   
   • Snapring
   
   
   
   



3. Press the wheel bearing and race out of the hub.

reverse is same but the lock ring must be set

to 123-180PSI. stop tightening above 123 at first alignment hole in lock ring..

could be a bad wheel bearing making the grinding noise. not that firmilliar with the grand cherokees,but that shouldnt effect the transfere case not shifting.

It could be the front cv joints even when the 4wd is not engaged. The wheels are set up like a front wheel driven car, so they have half shafts that go into your transfer case. Have a look at the cv boots, and see if its leaking grease, but then again, the mechanic who replaced your wheel bearings would have noticed something wrong.
If not that, and if it clicks when you are truning the steering wheel, the rack and pinion has lost its fluid. Might wanna check the boots on the tie rods and see if they are leaking fluid.

Lift and support the front of the truck so the front wheels are off the ground.
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

Before using the 4wd, did you have the transfer case, front differential, and front axle locking hubs inspected, properly lubed, and tested? No one ever does, so don't feel bad if you don't know what shape the 4wd components are in. You probably haven't used 4wd in last five months. Most people don't ever put their 4wd vehicles in 4wd mode, even though the service manual says to operate the vehicle for a minimum of 10 low speed miles every 3000-4000 miles. This helps maintain the proper function of any limited slip parts, internal bearings, and gear components. Operating in 4wd periodically also helps insure any electric devices are working. What you may be hearing is the unused front differential parts, transfer case bits, or electrically controlled locking hubs wearing out from the lack of use, proper maintenance, or just plain age (after all you did say it's a 2001). Front pinion and differential bearings are not usually ever spun/rotated unless the transfer case and hubs are locked in 4wd. If they were starved of gear oil, or dry when you went 4wheeling, you torn them up. Refer to the owner's manual (if you still have it) for proper 4wd opration. You'd be surprised that there are proceedures to do in order to maintain a reliable vehicle. Don't ever just drop it in gear and expect it to work..... I mean come on.... after all, It is a Dodge! Your next step is to find a full service mechanic, with a complete selection of tools and shop supplies (especally a hydrolic press) and schedule an appointment to have the 4wd front components inspected and replaced if neccessary.

SOUNDS LIKE YOU HAVE BAD LF WHEEL BEARING..JACK UP FRONT OF VEHICLE..BLOCK REAR WHEELS..PUT TRANSFER CASE IN NEUTRAL,SPIN EACH FRONT WHEEL BY HAND WITH OTHER HAND ON COIL SPRING..YOU SHOULD FEEL ROUGHNESS IN SPRING ON SIDE THAT HAS BAD BEARING..IT IS A HUB/BEARING ASSEMBLY

check the plugs on the front diff or on the back of the transfur case there will be a solenoid in one of these plases and it may need freeing up

Sounds like CV joint, or wheel bearing

Do this first
Usely the vibs you are getting could be from wheel balance wore out wheel bearings or flat spots on tires.
Only do this after you checked the front end.
(You could remove the fuse under the dash but the fuse that runs the 4wd also more than likely runs other things in the vehical. Or you can dissconnect at the transfer case would be .)

Is the noise in the front or middle? If it's in the front, it is most probably a wheel hub or differential case bearing. First I would check (or replace) all the gear lube in the transfer case and both differentials.
If the sound is under the middle of the jeep, it's probably a front output bearing in the transfer case.
