My 99 SVT has about 70k on it now. I drive it for the commute every day on the highway over 30 miles each way. I'm noticing a grinding coming from the front left tire. Only at highway speeds does this happen. I can feel the wheel start to grind a little bit once I turn the wheel to the right and then it gets worse the sharper my turn gets. I would say that it's the bearings that are shot but I could be wrong. I just bought brand new tires installed yesterday with a 4 wheel alignment. This problem was happening before yesterday but it was not as bad. I think the alignment straightened up the tires more so now the problem is more noticeable. Well I'm pretty much ready for new front bearings. My main question is what is the best way to go about getting this fixed? I can definitely do this job myself and with the help of a friend who is a master technician. Does anyone have any recommendations or tips on doing this job themselves? Is one set of bearings better than others? I'm also worried that the housing that holds the bearings might be wore down quite a bit and it might need to be refinished. Could this be possible or am I worried about nothing? Also, any idea on the cost of parts and where the best place would be to find them? I never go to the local parts store for my SVT. If I did that, I might as well eat government cheese!
Thanks guys
