had a rear wheel bearing changed on the bmw at the start of the year as it failed the mot for 'excessive play'. we were doing the rear discs/pads/handbrake yesterday, as when we came to the drivers rear, which had the new wheel bearing, we noticed that the wheel would wobble, when you grip the wheel top to bottom, and left and right.
after taking the wheel off it appears that everything is solid apart from the bit that fits inside the wheel bearing.
not sure if this is cause or effect, but i also noticed that every bolt that holds the driveshaft to the bearing was loose, they hadn't been thread locked when refitting (not sure if they were supposed to be or not?).
what i want to know is, have these bolts worked loose over the last 4k miles, and therefore given the wheel bearing too much play and damaged it, or could a faulty wheel bearing cause excessive play in the driveshaft and there for work the bolts loose to the diff?
so to cut a long story short, i know faulty wheel bearings can make a droning noise, but there was none of that, but can they colapse inside given too much play to the parts fitted inside it?
well bloody dodgy either way, glad we noticed it when we did, dont fancy the rear wheel overtaking us down the motorway
