Front wheel bearing question

[lgmagone]

It looks like I need to replace the right front wheel bearing on my Explorer for the second time...the last time I replaced it was just about 30 months ago.

When I replaced it last time, I did not put any antiseize or other chemical on the surface of the bearing that mates up with the vehicle - the two flat machined surfaces.

Do you think this will cause any problems with removing the bearing now? I don't know if you are supposed to put compound on these surfaces or not. I did put a bead of something (don't remember what) on the joint after putting everything back together.

Won't be a problem. Just replaced both front on our 05 Mountaineer after about two years and both came out fine. They come out easier the second time than the first.

the 2 flat machined surfaces needs to have a sealant so that moisture will not get into the bearings.

Do you plan on doing more work on cars?

Good, then go buy one of the $6.00 containers of antiseize, you will use it for a bunch of things. Is it needed? It sure helps. Do the pros add it, yes. Doe it help prevent rust and corrosion, yes. Is there any advantage to not using it, No.

I agree this is how I should have done it in retrospect, but I didn't do it this way.

I'm wondering if I can replace the bearings again, or if the machined flats are likely to be destroyed by rust and water damage.

If they are damaged, what will I need to do to repair? Replace more parts?

Trying to understand the scope of what I'm in for before I start to tear apart the vehicle.

chances are

there is a lot of metal in the spindle, it will just be rusty. The rust destroys the bearing more than the spindle. The rust makes it harder to remove the bearing.

You should be fine, just get out the sand paper or file and clean off the rust. You might see some pitting but really should not be an issue.

If you have any doubts, put in an low cost bearing. I put in one from ebay
Super Auto 515050 Wheel Hub Assembly that was $50 and is an exact fit, including the clips and length of the ABS sensor.

Most of the early failure of bearings is due to bad install, so make sure you clean the surface well. This will make sure your hub nut will torque to the right spec. Do not guess, go to auto zone or any and get the axle nut and torque wrench that will get you the 185 lb number.

Are the wheel bearings the same for 2WD ad 4WD?
I have ABS brakes. Is this just for the front?
