Q:2001 ford escape wheel bearings? (rear)?
Do not buy cheap mechanical will pay dearly for those cheap parts.
Q:Easy bearings please help?
If you carefully draw it out you will find that the angle YXZ is the difference in the bearings of 65 and 30. YXZ = 65 - 30 = 35 degrees as XYZ is a right angle or 90 degrees and we know the sum of interior angles on a triangle = 180 degrees, then XZY must = 180 - 90 - 35 = 55 degrees the length YZ can be found from the tangent function tan(XYZ) = opp/adj tan 35 = YZ/15 YZ = 15tan35 = 10.5 km
Q:how many ball bearings can i jam into my eurethra?
It depends on how big your shlong is. Just use enough to fill it halfway use plenty of KY jelly.
Q:which is better fkd bearings or black panther bearings?
BONES IS THE BEST. dont get anything else. theyre the fastest, longest lasting ones ever.
Q:Cost of replacing wheel bearings?
that does not sound like a bearing cause if it was a bearing you would here noise any time you move...if its make a noise when you turn its the u-joints that's an expensive job for sure.i had that same problem with my car and they had to replace the u-joints and the boot covers that go over them...$400 warned that i did not take me car in to shop till it was too late and my front wheel fell off..lucky i was just in town driving slow cause it it would have been on the freeway,wow!!!!! look under the car behind the front wheels there like a black boot cover (like the one the bottom on a shifter in a Manuel shift car) you can see if there torn,if they are its the u-joints for sure...(check both sides)
Q:cleaning solution for bearings?
get a rag wipe it off or take it to a store
Q:Which is better abec 3 bearings or 608 z bearings for skateboards?
608z Bearing
Q:What are the best bearings for a longboard?
bones are the bearings most wanted, but people usually go with mhs or mini logos just because of price. as long as they spin, they will work. just don't go spend $150 on some bones swiss ceramic abec9 crap that are barely better than some random $10 bearings you can get in zumiez. btw for boards look at kracked skulls. you can find many 5% off discounts on line.
Q:What kind of bearings/trucks does a Hobie board use?
any bearings will work, and you can find them at walmart
