Most front wheel drive wheel bearing/hub assemblies are not serviceable.
Rear wheel drive the gear lube in the center also does the bearings. Front wheel drive the back wheels can either be greased as you would a front wheel bearing or they may be a sealed bearing that can't be greased.
Need to know if it is 2 wheel drive or 4 wheel drive.
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.
Several possibilities: If you have an All Wheel Drive (AWD) model, it could be that the differential fluid is low or the differential gears or bearings are failing or one or both of the wheel bearings are failing. If you own a two wheel drive (2WD) model (which do not have a differential) it would possibly mean that the wheel bearings are failing.
If you are referring to the front bearings, you have to buy a complete hub assembly.
There are many different bearings. Need to know the year, make, model, front wheel drive, rear wheel drive, all wheel drive and if it is the front or rear wheel bearing.
If you don't replace bad wheel bearings they will seize up and break your drive axle. It would be cheaper to replace them as soon as possible.See "Related Questions" below for detailed procedures for replacing Windstar wheel bearings - really not a terrible job to do.
No, bad front wheel bearings would not prevent a transmission from shifting. If your car has bad front wheel bearings you will notice wheel noise or wheel looseness.
yes.. To my knowledge the rear wheel bearings are lubricated with the differential gear lube as you drive.
