Q:is there something wrong with the bones swiss black bearings i bought?
i dunno anything about skateboards but the first ones pretty! ....xx
Q:According to mechanic, wheel bearings make noise what should I do?
You need to find another mechanic or take it to a REAL mechanic. You absolutely should have the wheel bearings replaced before your repair bill gets higher as they fail. If you plan to keep the car, have them replaced on both front wheels. If you only plan to have the car for less than a year, just do the one that's failing. Depending upon the car, it can range from rather inexpensive to ridiculously expensive. Replacing wheel bearings is a normal maintenance item and to be expected as the miles add up.
Q:how to replace wheel bearings on a 97 ford aspire?
I already did replace a front wheel bearing on my 97 Aspire about six years ago. I needed a hydraulic press but managed to do it by using a socket the right size to hammer the bearing center down on the wheel flange tube. This wheel bearing is still working fine today on a car that sees 8000 to 10000 miles per year. I bought this car in July 2000 and it currently has 180,000 miles on it. I put Mobil one synthetic oil in it when I first bought it and it still runs like new. I do not recommend installing the front wheel bearings with a hammer. It's too tricky.
Q:Which Type of Skateboarding Bearings is the best?
If you are s street skater, then avoid ceramic bearings. They are designed for longboards, and can;t withstand the shock of landing, especially stairs. ABEC ratings are meaningless for skateboards they don't indicate speed or appropriateness for bearings. So... I;d go with the Swiss bearings. I prefer Pig Swiss, but have had good luck with Bones Swiss and Black Panther Swiss, but the Pigs need less frequent cleaning and maintainance than the Bones or Panthers. If you don;t want to spend the money, go with the Bones Reds, they are a high quality bearing at a great price, made to the same specs as the swiss bearings at 1/3 of the price.
Q:How do you take out a front rim bearings?
You'll need a tool called a slide hammer and the proper associated fittings to remove rim bearings. Personally, I wouldn't reuse bearings that were removed. These are often cheap enough to just purchase new without worry that soon you'll be replacing them soon. Since you're dealing with bicycle bearings, they're going to be pretty cheap. Industrial and vehicle related bearings will cost more. The slide hammer attachement basically grabs the bearing pack from the inside diameter where the shaft would slide through. the attachment is connected to the slide hammer. you hold the rim down and slide the hammer weight towards you or upwards in a fast motion.
Q:what brand of abec9 bearings should i get for my longboard.?
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:What kind of bearings/trucks does a Hobie board use?
I The truck mounting holes probably are the old long mount configuration. Tracker six track trucks will work for the old as well as the new hole configuration.
Q:Which skateboard bearings shall I get?
any swiss bearings will do good, bones and pig both make excellent swiss bearings. bones reds for a cheaper bearing or other brands like lucky abec 7, rush abec 9 seem to hold up great as well.
Q:If you have had a complete brake job done, is it possible to miss bad wheel bearings?
Back in the day a brake job would have included repacking the wheel bearings, but not today. A brake job on a ford focus does not require removing the hub. the hub of many of today's cars contain the bearings and can not be rebuilt or repacked, you replace the whole hub. if the bearing is replaceable it is a seal bearing and can not be repacked or inspected. There was no reason for Sears to inspect the bearings ( for $650 they should have gold plated your butt ). In the case of the focus it has a sealed bearing, it costs around $40 or you can buy a new hub for around $60. if you have basic tools you can replace the hub in about 60-90 mins.
Q:i have a question about skateboarding bearings?
sorry to say but that's the absolute worst set of bearings usually 5 is considered mediocre and 7 is perfect but in the end it only matters if you skate fast or not if you ever wanted to go with faster better bearings go with Independent bearing or the best of bearings~ Bones Swiss!
