Q:I have a 2001 BMW 325i. I believe that we need to change the wheel bearing (passenger rear). You can check my other questions in case the diagnosis is incorrect...(help??)Does anyone have any diagrams, instructions on how to change them? Is it necessary to have them pressed on/off? (that would determine if I could do this at home or not.Please help, this is my sons car and he is in the military and doesn't have time or cash to spend on it. So mom dad are trying to help them out. Any advice or websites will be appreciated.Thanks, stormphyre

You described the sound as something dropped and dragged? . A wheel bearing would usually make a growling sound, gradually get worse, and have to be really bad to lock up the wheel- unusual. Many BMWs with disc brakes in the rear had a separate parking brake which was a drum brake inside the brake disc. If it's rear discs, look for the parking brake cable. If the cable is attached to the brake caliper, never mind (I assume you've tried removing the caliper) If the cable goes inside the backing plate behind the wheel, you might try removing the brake disc and look at the small drum brake behind it. Replacing rear wheel bearings requires too many special tools and experience. I believe it'd be Independent rear suspension? You may be able to remove the swing arm and take it to the shop (save towing). Call ahead first - they may prefer to do it on the car. Cars with solid axles, the rear axle and backing plate usually is held on by four bolts on end of axle. It varies- repair manual helpful for that kind of thing.

Q:I have this set of bearings i got recently with my skateboard deck i purchased on ebay, the board and bearings are brand new from 1988, the bearings was in there original package. When i took the bearings out they dont spin very much at all. They only read 608 zz on both sides and they come with silver spacers. Are these good bearings and if so, how could i beable to get these to work more better.

Those are probably just cheap bearings that aren't any good. I would recommend just getting new bearings. Buy bearings from Bones, they are the best. Bones Reds are the most cost efficient and work really well (~$12). Bones Swiss are the next step up if you have a little more cash to spend (~$35).

Q:what are moter bearings and how hard are they to put into a gas engine?

There are different kinds of bearings in the engine, including main and rod bearings. Depending on which you need to change, it can be difficult or relatively simple. Main bearings are the easiest to change, you can access them by removing the oil pan. Take off each main cap and you'll be able to remove the upper and lower half of each bearing. Make sure to clean and inspect the surfaces for damage, and clean them really well. Lubricate the inner surfaces of the bearings after installing them with assembly lube. Be sure to torque the caps back on to the right spec. Hope this helps!

Q:i have bones reds bearings and i dont know if there abec 5 or abec 7 tell me what you think?

bones makes many types of bearings. Some are ABEC rated and the better ones are not. The ABEC rating is for vibration in high speed machines that run at speeds similar to skating over 200 mph. They are not the best design for skating but companies make a lot of them for other reasons and it is cheaper to get them than a design that is custom made. Bones, Twin Cam, Zero Drag, and some other companies have custom designs for their better bearings.

Q:I know it would mean changing a standard skating industry has been using for the past 30 years, but it would advantage longboarding enormously. Longboarding oftenly means bad pavements, rough surfaces, sometimes offroad which kills any good bearings in a matter of days. Now the bigger the bearing, the bigger its balls which means bigger tollerance, therefore longer life.Not to mention faster speeds.It would require a new line of trucks and wheels but I think it would be worth it.

just clean your bearings. not that hard. they do make 10mm bearings for 10mm axles on precision trucks though.

Q:when should i buy new bearings? i've had modus titanium for a year now should i buy some new bearings?

Well if they still work, why are you gonna buy new ones? I wouldn't buy new ones unless they get caught, or I totally bust it out. But if you buy new ones you will definitely feel a difference. New bearings are smoother faster and overal more comfortable.

Q:wats the difference between abec 7 and abec 3 bearings?

dude dont listen to these guys abec doesn't depends on the size of the number. all abec run the same. most skateboard bearings are abec 5 so i would stick with reds if your price range is low or swiss / ceramics(bones) if you have a higher budget.

Q:Front wheel bearings

You should feel a difference in the handling.It would be rare for both bearings to require replacement at the same time.You would normally hear a grinding noise,subtle at first but if you ignore the early signs you are risking serious accident or injury.A wheel bearing works under intense heat and quickly breaks apart when badly worn.At speed,you lose complete control of the car.When bearings fail,they fail big time.Get them checked and drive safely.

Q:How much would it cost to get bearings fixed on a fourtrax 250 Honda yr 2000, just a rough estimate please.?

Not sure which ones you are talking about here. If you are talking about the front bearings. Do you mean for one or both sides. Also remember this on alot of vechicals. Some are what are called pressed on and others are not pressed on. The ones that are not pressed on are alot cheaper to replace and if you and a friend are a back yard mechanics. Both of you should be able to do the job.
