Q:97 Prelude. What happens when the bearings and drive shaft go bad? How long before I have to replace?
Very unusual for front wheel bearing to fail. Why did you say drive shaft earlier? The car has CV axles that act like drive shafts. If one fails, you are going to have to have a tow. Jack up the car on one side then the other. Look for a shaft that goes to the wheel from the trans axle. There should be 2 boots per axle. If the boots crack they will be covered with dirt and grease. This will eventually precipitate the universal joint within the boot to fail and break. On wheel bearings, if they are bad, you may or may not be able to drive the car until one of them seizes. Then you will need a tow. Maybe you should get used to using public transportation. Either way, you are going to have to get your problem fixed. It's like my wife. Her Honda needs both CV axles, a timing chain and ball joints on both sides. I want her to drive my 89 Pontiac until I can fix her Honda, but she complains that she doesn't like the gas mileage on the Pontiac. I told her, what does it matter? She has three things that are eventually going to drop her in the middle of the freeway and maybe getting run over by a semi truck. I plan on sabotaging her Honda so she if forced to use the Pontiac. Don't get yourself stuck out on a limb. Either park the Honda and get on public transportation or get it fixed. By the way, my wife's Honda Accord has 450,000 miles on it.
Q:What kind of bearings should I buy for speed?
I use Bones Swiss bearings and they have been very responsive and have made a big difference. If you want to know how fast a bearing is most have abec ratings, nine being the highest. However, as Bones Swiss are of better quality and faster than most bearings, they have omitted the abec rating. I highly reccommend the Bones Swiss bearings and if you want to get better than those, you get the ceramics. They are much more expensive though.
Q:07 yukon wheel bearings?
you cant really go off miles in some cases. 87k miles is plenty of time to wear out a bearing depending on how it has been driven for those 87k miles. I ruined both front wheel bearings just driving through some deep water once and only had 2k miles on it. the harder you are on it, (bigger wheels/tires than what the factory recommends, off road driving, 87k miles of a speed demon) - will wear just about out any wheel bearing prematurely.
Q:Roller needle roller bearings can be used directly as a wheel?
Yes, it's the roller itself. However, as the use of wheels is not so good control, because the surface of the bearing itself after finishing processing, very smooth, friction will be very small.
Q:How to take care of skateboard bearings?
A bearing's biggest enemy is water. Keeping them dry is key. Never remove the shields unless you are cleaning them. Use speed rings or washers and don't over-tighten the axle nut. Use denatured alcohol, carb cleaner or brake parts cleaner to clean bearings. Never use water, water based chemicals or rubbing alcohol. Don't use gasoline it is dangerous and leaves a film that attracts dirt. Use only a skateboard bearing lubricant for lubrication. Other types are usually too heavy and will slow you down. Never use WD-40 it leaves a dirt attracting film as well. Clean them when they sound loud or lose performance. There are a number of how-tos on bearing cleaning on the net.
Q:Help with vectors and bearings please!?
using compass bearings: (2,60°) + (1,90°) = (2.9093, 69.8961°) - - - - - - (2,60°) = (1.7321, 1) - - - - - - (1,90°) = (1, 0) - - - - - - (1.7321, 1) + (1, 0) = (2.7321, 1) - - - - - - so: a) 2.9093 km b) (1.7321, 1) and (1, 0)
Q:should you replace axle bearings too if your replacing leaking axle seal?
not necessary. check them for wear and decide then.
Q:how to replace wheel bearings on a 92 toyota celica 2.2 GT?
Those bearings are pressed in you need to take the spindle to a machine shop and have the old ones pressed out and the new ones pressed in I have used my air chisle to get them out and my bench vise to install them but its a pain in the a$$ good luck
