Q: can i use rubbing acholhol?: You can go the fast way and put on some WD-40. That is the best way to go. To make sure its all clean, inside and out, you can also pop them off. Then soak them in gas for about 10 mins.

Q: I am building my own longboard and i would like to go fast so what bearings shuld i go for and if you have any suggestions for wheels too that would be great.: ABEC rating doesn't mean anything to skateboards. Take your board and drop it from chest height to the ground, now your bearings are rated far less than ABEC1. Just make sure they're clean and lubed and there'll be no difference in speed between $2 no-name bearings and $50 ceramics. Grab some VXB bearings. They're cheap and good. Instead of paying $45 for ABEC 9s, spend $45 and get 100 bearings (12 sets + 4 extra bearings), or spend $25 and get some with built-in spacers (makes sliding a lot smoother, unless you're using precision spacers in your normal bearings). As for wheels (which have a much larger effect on speed than bearings btw), 80a Retro ZigZags are some of the best all-around wheels. Very fast, grippy and smooth rolling. Other wheels to check out are 69mm/70mm 80a/82a Sector 9 Race Formulas, 80a or 83a Orangatang 4Prez, and Earthwing Road Rages or Smokers.

Q: my car recently (2 weeks ago started making a knocking noise like a chatter and i hear it coming from the engine. my mechanic said my main bearings are failing. he says the engine will last a couple years if i use a heavier weight oil. 2 years seems long. is that right?: Your mechanic is wrong. If you leave it like that, the bearings will continue to waste down and possibly affect the crankshaft which will be a lot more money that you will have to spend. if you have the means give the engine an overhaul complete with main bearings and rod bearings, rings, the works. it will cost you more in the long run if you just run it taking the chance.

Q: what kind of bearings go into a size 50mm , 52mm , 53mm and 54mm sk8 boarding wheels?: any bearings are fine.

Q: i want the best of the best, i want to get bones red bearings, but i want to know what the best trucks and wheels would be??? please help.: The best wheels are ricta Some good trucks are venture and bearings are lucky

Q: At speeds above 60km/h (37ish miles/h) my car starts to vibrate and it sounds like my tires are squealing, but when i am turning right vibration disappears and also the sound of the squealing, however when turning left it gets worst then going straight.This happened after i hit a curve and i got both steering and wheel alignment check. Also i installed another set of rims and the symptoms are same.: Right side bearing is strong possibility. Your right turns unload the right side wheels and the noise decreases. Your left turns load the right side wheels and noise increases. By the way your observation is the standard old school test for bearings that was done by swerving L. and R. at about 45 mph. That, and having Leroy ride in the back seat with the window down to help decide if it is front or back. If it is a bearing problem, just do the bad wheel or wheels and don't get talked into any additional bearings. The good ones could easily go another 150k. Sorry you wasted a bunch of bucks. Alignment folks usually don't touch cars with bad bearings or tires. Don't know what went on there.

Q: What exactly is the difference between sealed bearings and regular bearings and sealed pedals and regular pedals.: It all has to do with the bearing. Sealed bearings are self contained, you can't take the bearings apart to service you just buy new ones when needed. They stay cleaner longer because they are a sealed unit. Loose bearing can be serviced, taken apart and repacked, but they need more maintenance because they aren't the sealed type.

Q: i need to know which is better for my skateboard: I used to roller skate when I was younger and I had abec 1 bearings which were very good at the time but I heard that the higher abec bearings were better but I'm only about 70% sure about that. If your comparing abec 5's against abec 7's they probably don't even make abec 1's anymore so I'm guessing that 7's are better

Q: i was planning to buy a new bearing, but do they have different sizes? (sure answer pls......): Lets see... For a good deck I'd check out Plan B, ZooYork, or Zero they're all 3 pretty good brands. For trucks u have either Silver or Independent, I think Silver is better but that's my opinion. For bearings I'd go with either Bones or FKD saw blade. For wheels Bones would be a good buy as for grip tape u can either check out mob or check out Torey Pudwill's new brand called Grizzly Grip but it just came out recently so it may be hard to find in stores!
