How long do bearings usually last? My car has maybe 20 batts ran through it now and today seized a outdrive bearing. The other side bearing felt gritty. Also could someone tell me the easiest and correct way to remove these bearings they seem pretty stuck in place and do not want to come out.

My friend has a T2 ST and said he is on his original outdrive bearings. My kit was brand new a few months ago.

Did I just get unlucky?
