Angry Front Wheel Bearings

Well I have discovered a design flaw that will drive you nuts. I have an issue with a growling front wheel bearing. When I tried to pull the wheel bearing cartridge I couldn't get ist to move. I removed the spindle housing forging with the bearing cartridge in it and had to use a hydraulic press to get it pushed out. What I found was heavy corrosion in the bore bewteen the I.D. of the spindle housing forging and the bearing race O.D.. If you look at the spindle housing forging there is a relief for the ABS sensor. This relief allows water to pool in the crack between the housing and the bearing. In the winter this a a mix of water and salt. I believe this migrates down between the 2 surfaces and sets up the corrosion that freezes the bearing in place. So in conclusion if you are replacing the front wheel bearing you may have to remove the housing and use a press to push the bearing out.

Well that was adressed a long time ago. I had the same problem I had both my front Wheel hubs replaced. Get the sealed ones they last a lot longer and they dont cost as much.
