I dont know about Jeeps but when mine did it melted and damn near welded to the spindle

 

any truck that uses the inner outer replaceable bearings like the older solid axles and my truck will generally weld themselves to the spindle and possibly fall off.

on those uni-bearing ones, they generally just go poof and the wheel/tire goes bye bye...

 

It is the Hub and Bearing... OEM Part number 53007449 Cost of $265 from the dealer, Should take about 1.3 hours for an average mecanic to do the work, or about .9 hours for someone that does these alot. Here is the How-To for this assuming it is the 4.0L motor

HUB BEARING AND AXLE SHAFT

If the axle shaft and hub bearing are being removed in order to service another component, the axle shaft and hub bearing can be removed as an assembly.

REMOVAL


Raise and support the vehicle.
Remove the wheel and tire assembly.
Remove the brake caliper and rotor.
Remove ABS wheel speed sensor, if necessary.
Hub, Knuckle And Axle Shaft








Remove the cotter pin, nut retainer, and axle hub nut, if necessary.
Hub Bearing Bolts








Remove the hub to knuckle bolts.
Remove the hub from the steering knuckle and axle shaft, if necessary.
Hub Bearing And Axle Assembly








Remove hub bearing and axle shaft assembly, or axle shaft from axle. Avoid damaging the axle shaft oil seals in the axle housing.
Remove the brake rotor shield from the hub bearing or knuckle.
INSTALLATION

Hub, Knuckle And Axle Shaft








Thoroughly clean the axle shaft and apply a thin film of Mopar"R" Wheel Bearing Grease, or equivalent, to the shaft splines, seal contact surface, and hub bore.
Install the brake rotor shield to the knuckle.
Install the hub bearing and axle shaft assembly, or axle shaft, into the housing and differential side gears. Avoid damaging the axle shaft oil seals in the axle housing.
Install the hub bearing, if necessary.
Install the hub to knuckle bolts and tighten to 102 Nm (75 ft. lbs.) torque.
Install the hub washer and nut, if necessary. Tighten the hub nut to 237 Nm (175 ft. lbs.) torque. Install the nut retainer and a new cotter pin.
Install ABS wheel speed sensor, if necessary.
Install the brake rotor and caliper.
Install the wheel and tire assembly.
Remove support and lower the vehicle.



As always, any Grease gets replaced with AMSOIL Grease in my garage

 

got to love the older trucks replaced both sides bearings for like $15 lol..

 

Zach - that was the good ol days... When the trucks lasted forever too....

 

do you have a cd manual or something? cause you are full of how to's!

 

I wrote that all by hand

 

OK on a more serious note I have full access to shop manuals online for 99.9% of all vehicles from 82+. It basicly give you every detail you will ever need (as you have seen) for repairs and service. I do alot of service work on different vehicles out of my garage, and I have found that paying for this data is a billion times easier then trying to google it every time I need something.. Plus now I know it is true. I also have access to recall letters sent to the customers, and copies of what was sent to the dealer for a majority of the recalls too. < THIS saved my A$$ a few time! Well worth every .01 spent.

and maybe a little of this

This wheelbearing had little to no signs of wear but i'm sure if one gets really bad this will happen in a matter of time.
