4th Wheel Bearing Change - Front Left

Looking at my 4th wheel bearing change on the front left (102k miles). No issues on the other 3 wheels.

Anybody else see this many issues on one wheel?
Any suggestions for a more permanent fix?

How are they failing? mopar parts? Is it possible you are over-torquing the axle nut?

also add to that, are you using the axle nut washer? if your not using that, that'll as well when the nut is tq down pull the axle too far through the hub putting excess stress on the bearing.

I've had an issue with the same wheel bearing. I'm replacing mine for the 3rd time. This time around I'm doing both sides, hubs, lca, and tie rods. I'm wondering if I'm over torquing as well or the hub is bad. I heard a bad hub can blow a bearing. What parts are you using? OEM?

I always replace the hub when doing the bearings. Many owners found out the hard way many years ago that just doing the bearing will mean you're doing the bearing again in a year or two. Mopar or Timken Set49 bearings, whatever for the hub.

My experience.

From my understanding, Timken set49 is oem just without the mopar box.

Washer - Yes
OEM - yes

Over torque - No, looks like I am undertorqueing

I store it over winter, any issue for the bearing there?

Thanks for the help.

Storing is fine. Did you replace the hub(s) as well?

That bearing depends on that torque to stay together/work properly. How much under torque are we talking? How are you torquing your axle nuts?

Yes I will replace hub.

I used a torque wrench I had that goes only to 85 ft. I will get a bigger wrench.

Its pretty fucking crucial that the halfshafts/axle nuts be torqued to the specified amount. The S2000s from the factory came with axle nuts which were undertightened and people had rear wheel bearing failures. C5 corvettes used to be 112 lbs but had a service bulletin and now its 160lbs plus locktite. The srt4 is 180. Yes... 180. 150 stood out in my head because that's all a harbor freight torque wrench goes to. Yes I went out and bought a better one that does 250+ now.
