Q:how to replace a 2000 audi a6 wheel bearings?
How many miles does your car have? If it's less than 100,000 it's odd that it would need bearings already.If it's the drive wheels, they are torqued on and you'll need to replace the bolt with the bearings. The new bearings usually come with the bearings. In the non-drive wheels, it's easier. If you don't have the proper tools, it may be best to take it to a garage.
Q:How do i convert conventional bearings to true bearings? maths?
Bearings are usually measured clockwise from true north, so S is 180°, and W is clockwise from there, so we would add 47° to 180° to get S47°W has a true bearing of 227°.
Q:I have bent some of my skateboard bearings and now the wheels seem to go sort of wiggle but not badly?
If your bearings are dented, there is nothing that can be done about it. Either suffer with the wiggling until the bearings fail, or replace them.
Q:When u need wheel bearings will your tire come off?
Yes it can. Steve is completely wrong. I had this happen to me today. I started noticing smoke coming from the wheel bearing and then it started getting loud and it felt like something was breaking off in the wheel area. The abs light came on and I drove it around the block and then the wheel just popped off. It was crazy. Never thought I'd have something like that happen to me. I was lucky that I wasn't going fast when it happened.
Q:How do I repack the ball bearings on my boat trailer?
auto-zone sales a white plastic cones ,for bearing packing manually
Q:changed rod bearings can affect timing? plus a timing memory refresh?

Q:How Much is a Rod Bearings instillation?
why do u think u need con rod bearings replaced? if they are making a knocking noise u will need more than just new bearings crank will need regrinding. so the price could be any ones guess.
Q:Do you ever need to clean your bearings on your skateboard? If you do, then do you need to put oil on it?
i've had the same bearings for about 5 years and the only reason why is because of my bearing protectors. i have never cleaned them but i need new ones now. i dont think you should clean them. you should probably buy bearing protectors and you'll be fine. my board has been waterlogged about 3 times and my bearings still survived because of the protectors. well gl skating
Q:If you have had a complete brake job done, is it possible to miss bad wheel bearings?
