Good ole ABS Light - need help

[Tarbo]

Had a squealing noise coming from the front brakes so I decided it was time to remove the front wheels and check everything. Pads looked good (cheap pads so that is probably the culprit for the noise) rotors were ok but while I had the wheels off I decided to remove the rotors and took them down and had them turned. Did all this last Thursday, drove the truck everyday since and today (Monday) at lunch I noticed the ABS light come on for a couple of seconds and then go off. I quickly figured out that the light would come on when turning the wheel left. Not sure the "brake job" that I did has anything to do with it since it didn't start until today but I am at a loss as to why the light is coming on only when I turn the wheel left - only comes on when I get 3/4 of the way left to all the way to where it won't turn left anymore. Any ideas as to what is causing this problem?

The only time that my ABS light has come on was when I had a wheel bearing going out. It sounds like making a left turn is screwing with the tone ring.

My second reply since registering and it's the same subject as my first reply.

The ABS coming on at seemingly random times was one of the first indicators when my wheel bearing was going out. Relatively easy fix if you're mechanically inclined.

Did you guys have to replace the whole hub assembly for the wheel bearing?

Yep you do. It can also be the ABS wire if you pulled on it excessively while doing the brakes.

Good hubs are not cheap and take some work to R/R. Lift the front end and see if there is any play in the wheel assembly. If you don't find any, it might not hurt to take the chance on the cost of a new sensor before the work and cost of replacing the hub, especially if just after a brake job.

Camp Lejeune! Semper Fi bro.

Yes, as the other poster already replied, you do have to replace the whole hub assembly.

Lift the front end, check for wheel play, etc.

Swapping in a new hub assembly does take some time, but it's not too technically intense. Online tutorials will mention that it's a little bit of work to get the hub off of the spindle once the hardware is removed, but mine was seized to the axle. Long story short, that wasn't as much trouble as it might sound like, but it did slow us down a bit.

When my bearing went out, I was pulling into the driveway so the damage was minimal, but the bearing did technically quit working to the extent that it was not drivable. Point being that I damaged my brake caliper and rotor more than I realized and had to make multiple trips to the store so don't forget to check everything out before you get neck deep in the process. The pistons had over-extended which I didn't realize until I had everything buttoned back up.

Ya thanks brother I just bought the whole assembly so hopefully I'll be able to get it on tomorrow... Got some new ink getting done tonight the hub will have to wait while I drive the wife's car
