I have had to replace the front wheel bearings twice.
I have had to replace the rotors three times.
I have replaced the brakes 5 times.
Multiple electrical issues including resistors that continue to burn out, instrument panel lights that go on/off for no reason and a directional that turns itself on and off.
The front wheel bearings went at 30,000 and then again at 75,000. I have never replaced the wheel bearings on a car twice in my life - let alone at 30,000 miles!!!
The rotors began to shake at about 20,000 miles, were replaced, went again at 55,000, were replaced and then went again at 75,000. I drive mostly highway miles so there is limited stopping in my driving and no reason for the rotors to warp this often.
The brakes are the same way. To replace the brakes every 35 - 40,000 is acceptable. I have had to replace them every 15-20,000. That's crazy considering all of the highway miles.
Many people mistake highway driving to be easier on the brakes. It's actually not. It takes a lot more to stop the car when you're going 80MPH than it does when you're going 55MPH. Plus, if you're one of the many people that I see on the highway, you ride the brakes like crazy getting off.
I just had the bearings replaced in my car @ 50k. My mechanic felt that the wear ("I've never seen bearings so beat up") was due in large part to a shoddy hub assembly. Maybe that's something to look into in regard to your bearings problem.
