Q:Do cars have wheel barrens or wheel bearings?
Wheel Bearing. they help the wheel turn easier i think :D
Q:How do you CHANGE WHEEL BEARINGS on a Suzuki Quad?
use a long skinny punch to drive the old bearings out from the opposite side... then use a socket of the proper diameter and a hammer to carefully drive the new bearings and seals(when applicable)into place....I recommend buying the manual for your particular machine, they can save you a lot of money and headaches...
Q:Any hope for rusted bearings?
I heard that soaking them in Coca Cola will get rid of the rust (but you gotta clean them realllly good after). Otherwise, you can buy another set of bearings, then when some of them rest, mix and match and throw out old, rusted bearings as needed.
Q:Changing a camshaft without replacing the bearings?
yeah if they are not scored or pitted or damaged in anyway.
Q:Fork/bearings not fitting into frame?
In the place you put the forks you’ll see cones at the ends of both the holes, perhaps these cones are too big for you bearings. For eg; imperial cones forks to new metric cones forks, Bike companies would probably do this so you can’t mix their bike parts with other bike parts which in resalting you to buy the parts off them. I know it can’t be the bearings because bike bearings are universal and as such make them all the same (rather than crank and rim cone bearings which are a lot bigger and smaller). My verdict is to take of the old cones on you old bike and put them on your new bike.P.S. the threads on your forks might not be long enough anyway
Q:I just changed my wheel bearings on one front wheel. I hear a 'clunk' when going around corners left and right
This could be serious. The problem is not the wheel bearings. The problem is with the car doors. The 'clunk' sound that you're hearing is a person falling out of the car each time you round a curve because the car doors are not properly secured. This will also explain why there is less conversation in the car as your trip progresses. To fix this problem, just get a really big wrench and tap the door locking mechanisms a few times with it. This should get things working again. You may also want to revisit the route you took to pick up the people that had the misfortune of having to walk after falling out of your car.
Q:How good are ceramic bearings?
Ceramic bearings will not hold up to jumps. They are primarily intended for downhill longboarding and street luge. They would work as a speed skate bearing as well. Go for a Swiss bearing like Pig Swiss or Black Panther Swiss. .
Q:1996 dodge 1500 4wd do they have wheel bearings or just axle bearings?
Sounds like a ball joint.
Q:Cleaning out my skateboard bearings?
first of all NEVER use things like hyd. peroxide or sewing machine lube or WD-40. it clots up, collects more dirt and actually can cause more friction between the ball bearings and the shell. and absoloutly never use water, unless you want rusted shackles. only use actual skateboard lubricants, top kind out there right now is Speadcream by Bones.
Q:can the front bearings be regreased in a oldsmobile alero 2003?
No they are sealed bearings.If you have a bearing noise the most simple way is to buy a hub/bearing assy.NAPA can get them alot of the time when you got a noise up there its not the bearing,its the axel/C.V. joint.If the boot is ripped open it prabably needs a axel.The bearings don't fail nearly as often as the axels.
