It can be very dangerous. You certainly don't want to be on the freeway when the bearing finally goes and the wheel falls off. Yes. Definately. If the grease is completely gone, the bearing can heat up and get so hot that the wheel could lock up and cause the car to spin out of control.
Bearings on Inifinitis should be replaced after every 30,000 km. If not, they can start grinding with or without noise. If you drive in this fashion for a while, you risk losing a wheel.
Wheel bearings or shock needs replaced at that corner. Unless of course ur missing a cat o_0
Need to know if it is 2 wheel drive or 4 wheel drive.
Depends on the vehicle and which bearings. Wheel bearings, not so expensive. Main bearings inside the engine, expensive.
In most cases wheel bearings cannot be repaired and must be replaced. Remove the tire and wheel. Remove the axle end cap. Remove the wheel bearing seal. Remove the wheel bearings. Reverse the process to install the new wheel bearings.
2 wheel drive or 4 wheel drive? It makes a difference.
WHAT YEAR IS IT? is it four wheel drive, two wheel drive?
It depends what year they are and if they are 2 wheel drive or 4 wheel drive.
You can drive until the bearings fail, but this risks causing other damage and making the repair more expensive. If you know the bearings are failing and you don't plan on getting rid of the car in the near future, you may as well bite the bullet and get the bearings replaced.
If you are referring to the front bearings, you have to buy a complete hub assembly.
Front or rear bearings? 2 or 4 wheel drive? year of truck?
yes.. To my knowledge the rear wheel bearings are lubricated with the differential gear lube as you drive.
