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:Can skateshops clean bearings for you?
Yes, they can/ should be able to do that there. Since you said in your other question that you have ceramic bearings, the cost of this cleaning/repair would be alot cheaper than new bearings. I would take it in and see how much they charge, what they suggest, and how confident they are that they can fix it. If they charge alot then just ride them till you notice a decrease in performance. Then take them in and get them cleaned. If they don't charge much and sound like they can easily straighten out the cover, then ya, go for it.
Q:how to clean bearings?
Ammonia is really a great cleaner you might give that a try.
Q:Do all skateboard bearings have 2 sides?
most of them have two sides. I believe that abec 7 bearings have two sides but i am not sure. google abec 7 bearings and that should give you the answer
Q:Skateboard bearings problems/cleaning?
Yeah guy. of direction which would be advantageous. i've got achieved that earlier while i became into youthful because of the fact I had no longer the rest lol. Yeah, purely placed it on and roll your wheels and placed greater on. try this for some days in a row and your bearings would be spinning and spinning and spinning!
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:How to put in balls in bearings?
I have found that impossible to put back in, trying to do that with skateboard bearings. I would rather recommend replacing the bearings with a new set. Since the balls have broken out of the race way, it will not perform too good. Either grinding unevenly against the walls of the race way, or not spinning at all.
Q:some good teaching MOTIVATION or VISUAL AID on "BEARINGS" (trigonometry)?
Depending on the age group, one of the resources I use is a print from googlemaps of the school. The students have a route they have to plan around different rooms faculties using bearings distances (scales). Make it as hard / easy / fun as you wish. Or a similar idea using a print of an estuary, with shipwrecks marked so they have to either avoid or hit as they wish. They seem to enjoy the crashing part! Other than that, here are some interactive websites to try: (bearings is near the bottom of the page) good luck
Q:ball bearings for a mousetrap car?
if your axle shaft was solidly mounted to the vehicle, perhaps even a threaded bolt, and nothing touches both the inner and outer races, you could just tighten the nut on one end and it would stay together. i would suggest using a locknut, which can be left loose without loosening up from vibrations or the spinning wheels. i might suggest roller blade wheels and bearings. abec 9 bearings are very good low friction bearings, or the bones brand ceramic bearings are even better. with a large profile wheel, a wheel that covers more distance per revolution, a set of abec 9 bearings can allow a good roller blader to hit speeds of over 70 mph. and roller blade wheels are setup with their bearings to be through bolted fairly tightly in place, which might be ideal for your setup. another thing may be skateboard parts. the trucks, if tightened up real tight to prevent lean steering, might make very easy to use axles that are meant ot have wheels on them.....
Q:are shortys black panther abec 7 good bearings and are they better than bones?
Look at the abec number it will usually tell you. I agree with the post above, lucky 7s are the poop!
