- Q: The noise it is making is a high pitched sound that sounds like a squeaky wheel. Gets worse in 4x4.How do I change the bearings or do I have to take the truck to the shop. I can do most basic repairs and have access to most tools needed. Thanks
- If it was 2wd I would say you could probably do it yourself. However, the locking hub assemblies on 4wd need special tools and are a lot more complex than a standard truck front hub. This is definitely a shop job. Also it may not be the bearings themselves but the front driveaxles may have some problems. Ask a shop to verify exactly what is wrong first. Good luck.
- Q: This may seem like a stupid question as I am just learning to skateboard.I bought a brand new complete board with abec 5 bearings and they seem quite stiff. Am I suppose to oil them before I ride or do they eventually loosen up as I ride? Also I took the riser pads off because I heard it makes it easier to learn to ollie, will this help me? I have 51mm wheels so I dont think they will rub against the board.Thanks for your help.
- The boards do could desire to interrupt in in the previous you get the optimal sense of it. as far because of the fact the turning is going, you are able to attempt and regulate the tightness of the autos if it would not be sure over the years. The wheels will extremely get greater desirable over the years.
- Q: I got some bone reds from zumiez and second day they lost spin. Whats wrong with them?
- your bolts might be too tight, or the bearings were not pressed in all the way, or you just got a defect bearing. Just take them back and ask for help and support local shops not chain skate shops
- Q: A friend who's basically tutoring me in cars and their different parts told me that as my first assignment I was to find out what exhaust bearings were and what they did. Can anyone help me out?
- to define bearings is to say a component used to reduce friction. they are broadly classified due to the motions they allow. the donut gasket that seats your exhaust pipe to your exhaust manifold performs a sealing action but also acts in a micro manner as a bearing as it allows for the allaying of friction where these two metal pieces mate. by the same definitions your muffler and tail pipe hangers perform the same purpose as they, in sustaining the weight , allay , once again, the friction and the twist of the metal they support. i hope this addresses what you were looking for.
- Q: How do I work out this bearings problem?A helicopter flies 15km on a bearing of 053, then 7km on a bearing of 112. How far north is the helicopter from its starting position?
- This problem needs some thought since when you use directions North and bearing 0 degrees is at the top of the page But, in math, if you use degrees, 0 is usually to the right. To translate, so your calculator will give the correct answer, subtract the bearings from 90 degrees. So 90 degrees minus 53 degrees equals 37 degrees. The distance to the east is equal to cosine of 37 degrees times 15km = 12 km Sine of 37 degrees times 15km equals 9km So the first leg he ended up 12 km east and 9 km north of original position. Then to translate the 112 degrees, subtract it from 90 to get -22 degrees Cosine of -22 times 7km equals 6.5 km and Sin -22 times 7km equals -2.6km. The second leg took him 6.5km farther east and 2.6km south since the 2.6 was negative, it is in the direction south. Next, add the two together Cos + Cos for the travel east and you get 12 + 6.5 so he ended up 18.5km east of the starting point Add the Sines for the north/south directions. 9 -2.6=6.4 km north of starting position.
- Q: So i took my bearings out of my skateboard to clean, and now i can't get them back in! I know that pounding it dents it, because i tried it before and i ruined my bearings. but its too hard to push them back in with my thumbs, i have the hard wheels. Somebody help me!

- This Site Might Help You. RE: Im paying $1,200 to replace rear differential bearings for a ?
- Q: how can loose fits cause failure in bearings? and in particular affect the outer diameter?i am seeing a failure catalog for bearings, and i read : discolartion and scoring is the result of the outer ring slipping in the housing. why outer ring?
- The usual condition for the shaft to turn in a bearing is the inner surface of the bearing where the rollers or balls contact the shaft. This location is usually well lubricated and the contact area on the shaft is very minimal. Very little friction is generated and therefore very little heat is generated. If the outer race, surface, spins in the support a very high unlubricated contact surface is present and considerable heat is generated. This is known as spinning a bearing and it is not good and usually the result of the bearing race not fitting tight enough. If the friction fit in the bearing support is less than at the bearing / shaft the bearing will spin and generate heat. The heat will discolor the shaft and the individual bearings will be scored. The bearings out side diameter must be such that a tight fit is achieved when the bearing is installed.
- Q: just for crusing
- This Site Might Help You. RE: what are the best bearings to put on a stereo vinyl cruiser (skateboard)? just for crusing
- Q: What is the reason the inner ring of some roller bearings are tapered, while others are flat-bored. What are some of the typical applications for roller bearings that are tapered on the inner ring?
- tapered roller bearings not only can support a radial load, but they can also resist an axial load. This makes them useful on helical gearshafts because helical gears give axial loads. You can find these in transmissions, many types of gearboxes, many places that have rotating shafts which may require that the shaft be subjected to axial loads.
