I've noticed a low frequency noise coming from my left front wheel. I suspect the wheel bearing, but can't find any definitive answer if they can be serviced or not. I was considering pulling off the hubs to check them out and repack the bearing, but I've seen posts that say that they are sealed and can't be packed.
My Miata has 90K miles and I've not done anything to the wheel bearings...
Can anyone please provide info if they can be serviced and if so what is the procedure.
thanx, mark
