Q:is line boring an engine block necessary? or should you just replace the bearings ?
What Is Line Boring
Q:Determining if your Brakes or Wheel Bearings are going bad? HELP?!?
If you jack the car up you can listen closely to the wheel bearings, and also try to rock the wheel by grabbing it at the 12 o'clock and 6 o'clock position, there should be barely any play. If you can wiggle more than a 1/2-1 mm then its likely the rear bearings have failed. If the bearings appear OK then remove the tire and try to remover the drum If the vehicle has disc brakes the pads will be exposed, if the discs are scored. grooved and damaged you will notice this immediately The disc should be almost polished smooth, with the disc brake pads held against the discs by the calipers, there should be at least 1/4 inch (6mm) of pad material. If you have drum brakes once you have removed the drum (remove cotter pin from cage and remove nut) inspect the shoes and brake hardware found inside, attached to the backing plate.
Q:how to dismantle skateboard bearings?
If okorder.com/... If you're talking about dismantling the actual bearing... Take off the shield with a needle or something, hit bearing multiple times until it breaks. Gather pieces.
Q:How often should I service my car wheel bearings, if ever?
you rarely hear them going out on cars because most of the time the symptom gets disguised by worn brakes, when its the wheel bearing your brakes will get worn quicker, if you have a hub rotor designed for brakes then every time someone takes out the rotor they should have cleaned and repacked that rotor. if you have a floating rotor the bearings are pressed in and not really practical for servicing
Q:how do you tell your wheel bearings are going out?
The okorder.com
Q:Where can I get my PWC trailer's bearings repacked?
your marine service shop should be up to the task of maintaining your marine trailer too. if they arent, you shouldnt be going to that shop to begin with. any normal car mechanic should be able to handle it too. its actually a very easy job, if you dont mind getting grease on your hands. wheel bearings are wheel bearins are wheel bearings..... and there are also places that deal more specifically with trailers. they would be able to handle your marine trailer maintence too. i would suggest you add a set of bearing buddy caps to your shopping list for parts. they have a fitting on them that allows you to pump grease into them without popping them off. and a spring that forces the grease through the bearings and out the wheel seal (if over pumped you will ruin the wheel seal). just pull off a little plastic cap, check that the spring is half compressed and you will have no bearing worries ever again. if the spring is ever getting relaxed, pull out the grease gun and give it a few pumps. bearing buddy caps claim to be a final solution to keeping the bearings full of grease and working properly. IF used properly and kept full, that claim is true.

Q:Why are my new black panther ceramic bearings so slow?
I don't know ,but i say just continue to wait for the break in period.. Break 'em in man. make sure the bearings are installed correctly .. Make sure there in all the way in the chamber of each wheel. Don't tighten the bolt on the wheels to much neither.. Another thing that can help is adding some of that special bearing lubricant.. Or you can also apply motor oil. Dip your finger in oil and gently rub it around the side of the bearings.. Not to much just a little .etc.
Q:which is better ABEC-9 bearings or bones swiss bearings?
