Q:make more noise when they are in rictas?: get bonesreds or bones swiss because what your hearings is the bearings I know I heard that to with mine so its not you. GOOD LUCK HOPE THIS HELPED

Q:I have a 98 Jetta GL and my left rear shock absorber has begun leaking fluid in the past month or so. I have also had issues with the bearings wearing out, so I had them replaced less than 2000 miles ago. But now these newly installed ones are giving me the telltale signs of going-to-crush-soon. Could a failing shock absorber cause uneven wear/premature failure of my rear wheel bearings? I know that the bearings were installed packed correctly.Also, on the hub assembly the nut that goes on just before putting in the cotter pin tends to loosen after about 50 miles of driving. I continue to tighten it, then back it off slightly but the problem still occurs. This occurs on BOTH rear wheels. I am at a loss for what can cause this. Help!Thanks!: If you disassemble the rear wheel bearings wash them out and wipe them clean I think you'll find your problem. Once wheel bearings are packed with disc brake grease, snugged not tightened, wheel spun by hand spun and castle nut backed off, there's no need to ever screw with them again.

Q:I went and had my local bike shop put a new freewheel on my bike today. While he had the wheel off he wiggled the rear axle, told me it was loose, and offered to adjust the bearings. Now my back axle makes a pinging noise while I'm riding. The noise is gone when the bike is on the stand with no weight on the axle. Can this be fixed and how much will it cost?: The tech really should have looked further. My guess is that the reason your axle was loose is because either your axle is bent, the bearings are toast or your hub is shot. Unfortunately, these things often go hand in hand. Here's the progression in a worst case scenario... 1) The bike is ridden in a manner that causes the axle to bend; 2) With the axle bent, the bearing cones are compressing some of the bearings and crack one or 2 of them; 3) The pieces of the cracked bearings get jammed between the good bearings and also crack those, plus they jam themselves into the races of the hub destroying the bearing surfaces. Yuck.

Q:what kind of bearings are better for a skateboard???: all skateboard bearings will work, any swiss rated bearing will work best, they'll last longer and ride smoother. abec isn't a true rating for skate bearings so you cannot really go by that, abec 3's could be better than abec 7's you just never know what you're going to get. I like all bones brands even their cheaper reds are great. Any swiss brand is good.

Q:I have reds bones bearings and they were all fine until today. I got them over a month ago and haven't cleaned them. Today I ran over a pebble going fast and fell. Right after that my bearings on one of my wheels stopped spinning. I could ride but they don't spin when I spin them with my hand. I think something got in the bearings. It's both of the bearings in the wheel not just one. What could I do to check if there's anything in them? What do I do if there is? And how do I clean the bearings? What do I need? Thanks for helping!: Here are some good links to visit. What I do is: Pop of the sheild with a small nail, or you could use a thumbtack Clean them with a reccomended cleaner Ex. rubbing alcohol Spin them pinching the middle with my fingers to remove dirt, Dry them, Put the sheilds back on, Wipe the bearings with the sheilds on, on a old towel to make them look new, And put some Bones speedcream in them, Put em' back on the wheels. Hope this helps.

Q:Ive put some 18 wheels on my car (which shouldnt be a problem because I know people with bigger ones on a golf) as soon as they went on, the car makes a howling noise from the front, a bit like a wheel bearings gone, or they are catching on something? There are no scuff marks on the wheels or tyres and I got a mechanic to check the bearings and they are fine, It sounds worse when the car is slowing down, ive also had the wheels checked and balanced, there is nothing wrong with the alloys but one of the tyres was slightly mis-shapen but ive been told thats not the problem, any ideas please? Dont feel safe driving it until I know whats causing itThanks: Hi, the front wheel bearings on the golf's are not a tapered type and are very hard to check for freeplay / wear when car is jacked up...I have worked for VW for 30 years and changed many of the front pressed in type bearings....the only sure way of testing which side bearing is noisy is to spin the wheel up to a high speed with car jacked up and feel the bottom of the shock behind the wheel hub were the hub is bolted to it, if the bearing is worn you will feel a grinding sensation through the hub. This can be very dangerous if you are not careful....we used a mobile wheel balancing machine to spin each wheel up while, it was jacked up on one side... I would not try this if I was you with no training...Get a 2nd opinion from your local VW specialist or come and see me if you are in NW UK...

Q:I would like to ask about the difference between needle roller bearings NK and nki,Recently, I encountered a problem, originally wanted to buy NK 40/20 needle roller bearings. But it is later discovered that the label is NKI bearing 35/20 (inner) model, measure and NK 40/20 nominal size, only found nki35/20 needle roller bearings NK 40/20 bearing needle length is shorter a section, the other to look exactly the same.Considering the bearing equipment used in high precision, and the bearing capacity is large, so request, the use of NKI35/20 (inner) bearing replacement prototype No. NK 40/20, it has a bad effect on the accuracy of the equipment, whether this model can be used to replace.Therefore, I always have this doubt, hoping to get answers from professionals,.Thank you for putting it down hereWhat I want to ask is, if you take the NKI 35/20 inner ring off, can you take the place of NK40/20 bearing?If the NKI 35/20 bearing is installed, what impact will it have on the equipment?: Hello, I am a professional sales of bearings, NK40/20 bearings with inner ring called NKI35/20, NKI35/20 went to the inner ring is NK40/20. in the industry just code in different ways, the other the same, the difference is an inner ring with a ring. A thing, of course can be generic, the quality difference is negotiable. As you mentioned inside the needle is not the same, that is for sure, because the internal structure of each of the manufacturers are not the same, sometimes the size of the needles of different lengths is very normal, especially domestic generally not unified. If this bearing higher requirements with the best inlet of the "INA" or "IKO" two brands of domestic use. "FYB" is a German.INA company, now belong to the Schaeffler Group.IKO is Japan's Tom Xun.FYB Corporation is domestic Zhenjiang Feiya bearing company.INA is the ancestor of the needle bearing company, IKO is then introduced INA technology and products Do the products with the INA series, the material will be worse, the accuracy of FYB is similar to the imported INA production line, the needle roller bearing is currently doing the best, although the price is cheaper than Japan, but the quality is not to say, to be roughly the same small Japan.

Q:i have an 2001 ford ranger and it sounds like a bunch of rocks or marbles sound coming from my rear wheels. does that mean i need new bearings?: If the noise increases with speed yes, check your rear differential to see if its low on fluid and get the bearings changed out. Bearing seals also may be leaking diff oil over your rear brakes.

Q:Both the same size rimes both bmx. But one rims bearing don't work good anymore. How can i put in new ones?: If it's a front wheel, just unscrew the cones and put in the new bearings.

Q:i just bought a new set of bearings and put some lubrication on 'em. but when i put them in my wheels and spun them they make a little grinding noise. i don't know if this is normal or not but any help would be appreciated.: What kind of lubrication did you use? It sounds crazy, but with some bearings, if you used motor oil (as in 10w/40 or whatever) you can actually ruin your bearings. I killed a set of tensor bearings this way a while back. Same thing too, bad grinding noise and they kinda seized up a little too. They'd still roll, but not very well at all. Once I figured out that plain old OIL can be bad (which I still can't believe), I've just been sticking with Bones Speed Cream because I don't want to have to think about it too much.
