LLY Wheel Bearing.....

So, I'm cruzing down the freeway tonight at about 85..... and the ABS light come on.



Which is weird... since it's never come on before, and I had not touched the brakes.

Then, about 10 miles later all hell breaks loose, and between the noise and vibration I think the right front wheel is going to leave!! I pull off, limp it home on city streets and get it into the driveway.

I jack it up, and the bearing is toast! It even started to turn blue.( old on the left, new on the right)



They are easy to change, so I swap it out in about a hour. Theres a few how to's posted on the site, in case you dont know the procedure.

The moral of the story? About 2 years ago https://dmaxstore.com/ had a good sale on Timkens, so I picked up a pair. 2 for $400, or something like that. They have been sitting on my shelf, just waiting for the day....

If you own a Duramax for ANY length of time, things will go wrong!

Plan ahead, and get your spares in place before you need them... and when the site vendors have a sale, there is no better time to do so!!



Also, if your driving (or Towing!) and the ABS light comes on, remember this thread and check your wheel bearings!

I give the wheel bearings a shake every time I've got it up on my hoist. Replaced both, one about 40K miles and one about 20K miles ago. I tow a lot and don't relish the idea of having to replace one a long way from my shop...and toolbox...

This is why I carry pretty much my entire tool box in my box on the truck. Given I wouldnt have had a wheel bearing with me but could do it in a parking lot after buying one.

Nope, just some Michelin LTX M/S2's.

I live at the bottom hill and I have to turn left to get on my street ( which loads the right side bearing)

About a week ago I thought I heard something making this turn, but I never heard it again, so I just blew it off.

Dumb, it was trying to tell me something.



I swapped out the left side today, it appeared fine.

My wifes Tahoe just had a wheel bearing go out. She did say it makes a squeaky noise and I told her it's just a grain of sand in the brakes and keep driving. Well she complained again about a week later so I took it for a drive and I didnt notice anything. When I got home I felt the tire tread and drivers front had irregular wear on the inside. So I jacked it up to have a look and as soon as the tire left contact with the concrete I saw the tire move. I could move the top back and forth about 2"! So I replaced that hub, and she says it drives so much straighter now with less wandering. I rotated the tires on the last oil change and didnt notice anything unusual so they can go out pretty quickly with minimal signs.

I had to put one on my truck after getting stuck and being pulled sideways. Wasn't 2 weeks after that is when it went bad. I wasn't happy that the Moog wheel bearing was made in China after all my other Moog parts were made in the USA.
