Posted: Tue Apr 08, 2003 3:23 am Post subject: Front Wheel Bearings |
|
|
Ater coming home from a recent SCCA Driver's School at Summit Point WV, we found that our left front wheel bearing was shot. The right side was fine but the left went bad. Now before anyone responds with the question - "was it packed right?" - the answer is yes. I believe that because there are four corners at Summit Point (turns 1, 4, 8, 10) they are all fast right turns where all the load is on the left front wheel. Do you think that would be the cause of it going bad? does anyone else exp. this with their car after a race weekend, or DE or track days? I believe that we may just have to live with it and expect the wheel bearing to be replaced after every event at Summit. We could also have a defective part and therefore never have an issue with this again. What do you think?

I'd suspect something was wrong - part, grease, or preload.
I find that I want to re-pack my bearings every year. Preventative, haven't trashed one yet. I use Valvoline synthetic grease (so I can use the same on my CV's). It is wise to check the play in the bearings before you head out every weekend, along with checking all critical bolts in the suspension for loosening, and tighten them up if necessary. If there's a lot, you may wish to pull the cap and inspect/repack, make sure the bearing isn't going.
BTW, to make checking the rest of the suspension bolts easy: clean/paint all components. Mainly clean, clean all the grease and dirt off. Use a paint marker to mark any bolt or nut that's remotely critical with a line. Then you can easily get under the car and verify that everything's tight with a quick visual inspection, don't even have to get one wrench out. Not only does it simplify between-race action; if you hit something or someone, you can very easily and quickly pop under the car and evaluate if your alignment was disturbed. I have on occasion had the rumble strips loosen my alignment up, and this not only allows me to quickly detect it; it also shows me about where it needs to go back to, speeding up repairs. _________________ Vaughan Scott

Jeremy:
Agree with Vaughan. Something just wasn't right. Who knows.
I also used synthetic on the wheel bearings; but use the special 'high tack' grease on the cv joints. If you guys want some I can put you in touch.
