Front wheel pops when you turn?
probably the a fram
You will hear a grinding noise. Driving down the road turn the steering wheel sharply to the left and if the noise goes away the left front wheel bearing is bad. Turn the wheel sharply to the right and if the noise goes away the right front wheel bearing is bad. Be careful and do not turn the wheel too sharply or you may loose control. Or you can simply jack up the front wheels…
get cardboard- beer- small sharp screwdriver and tour paw. Don't open hood -drink a sip of beer - if right turn signal turn front wheels to left-sip beer- sit on carboard by wheel -take small screwdriver or knife and in the wheel well there are two bayonett type fastners holding the plastic mud guard to fender-they are about at 12 and 3 oclock looking at wheel-- pry out slightly the inside plug-the fastner should be…
Have a roaring noise in the front end. It's louder when you turn the wheels to the right. Could it be wheel bearing or the four wheel drive?
Is this true or false the handlebar of a bicycle is an example of using a wheel and axle to reduce the amount of force a rider needs to turn the front wheel?
Something is a bit confused here. The handlebars are levers that are used to turn the front wheel. It would be much more difficult to steer the bicycle just using the fork steering tube. The front axle and bearings essentially reduce the friction verses, say sliding/dragging the front wheel forward. High quality bearings, bearing races, and grease reduce the rotational friction and thus reduce the amount of energy required to turn the front wheel.
If you hear a noise you suspect is a bad wheel bearing try this. While driving slowly turn the wheel sharply to the left. If the noise goes away your left front wheel bearing is bad. Now, turn sharply to the right. If the noise goes away you right front wheel bearing is bad. The only 100% sure fire way to know for sure is to remove the wheel bearing and inspect it.
