Q:how many bearings in rearend of 2001 Ford Sport Trac ???
There are a total of SIX bearings in your rear axle assembly. If you have a leak from your axle seal, you only need to remove the brake rotors and axle shafts for access to replace the seals.
Q:Grinding and clicking noise - Wheel Bearings?
It could be bearings or differential
Q:Skateboarding- Best trucks, bearings, wheels for a beginner?
I would suggest if you are buying a Mini Superlight, it's gonna be a pretty darn light board. I woud suggest buying the lightest wheels and trucks you can find out there. Trry your local skate-shop, and ask them if they have any DESTRUCTO brand trucks or KRUX brand trucks. I have destructo RAGDOLLS, and they are pretty light. I recommend HUBBA or RICTA brand wheels. Don't buy huge wheels though. Buy about anything under 58 mm if you can. Remember, look for RICTAs. I recommend REDS bearings. They aren't too too expensive, and they work awesome. I have REDS Bones bearings. They cost about 15 dollars to 20 dollars Canadian. If you are willing to spend the $$$$ though, buy PIG or Black Panthers bearings. I don't recommend buying NINJA bearings, though. Yours Truly, Garrett Ibbitson.
Q:How can we reduce friction by using ball bearings?
They are balls and because of their shape, they create less friction than something that is flat or has edges. Edges tend to dig in or scrape against other edges. The roundness of ball bearings allows them to roll with the objects.
Q:Could differential bearings cause loud noise and jerking of the car?
My motor vehicle had the comparable subject final wintry climate sound like the fan belt the subject with mine become i had approximately 3 or 4 fan belts and that all of them broke the subject become the cogs that turn it around certainly one of them become no longer turning so good so i had to circulate get it fastened so if it keeps doing it as quickly as ya positioned a clean one on take it to the storage
Q:I forget hot to change the bearing s in my hockey skates, and what skates/bearings would be best for missions?
First, you need to know which size of bearings you have. Most skates use 608 bearings which are about 7/8 outer diameter. Many hockey skates come with 688 bearings which are 5/8 outer diameter. You can use the other size, as long as you replace the wheels and bearing spacers at the same time. The other thing you need to know is which axle size you have. 6mm axles are about 1/4 and 8mm axles are about 3/8. For 6mm axles, you push the thin edge of the spacer so that it pushes the far bearing out the other side of the wheel. For 8mm axles, you have to pull the near bearing our towards you. The easy way is to use a bearing tool or 1/4 socket handle to roll the bearing out. Much easier to show than describe. Any quality bearing will be great.
Q:Are these good bearings for a skateboard?
no, okorder.com/
Q:what kind of bearings go into a size 50mm , 52mm , 53mm and 54mm sk8 boarding wheels?
all bearings are the same size and all wheels have the same size inner part where the bearings go so that the always fit
Q:loose fits and bearings?

Q:Can wheel bearings cause humming noises?
The steering wheel vibration most likely will not be from the wheel bearings, however the humming noise from the front area could very well be from the wheel bearing.... a simple test for this is to drive to an are that is not busy and then slightly turn your steering wheel to one side and listen for an increase in the humming noise.... this will indicate a well worn wheel bearing on the load side ( the right side bearing if you turned the wheel slightly to go left.. and the left side bearing if you turned the wheel slightly to the right) Front wheel bearing noises are also common to C.V Axle replacement and then the large nut at the center of the wheel not torqued properly... good luck hope this helps.....
