what causes wheel bearings to go out? when i swapped my b20, the rear motor mount broke. drove on it broken for aobut 3 days till the passenger side wheel bearing went out. got a solid rear motor mount and new wheel bearing and drove agian... been driving for a while and my driverside went out! drove on it messed up for about a month... just replaced it 2 days ago and already its out agian... any ideas? :worthy:
basically just like any bearing. Being unlubed, really really old, or high temperatures caused by friction. But in your case it seems like since you broke your rear mount that it might have been slightly tweaked in there. That could have caused premature bearing failure.
