How long did it take before you had to replace yours.

Or maybe it was that pot-hole, that's why I have to change mine.

Right rear was replaced at around 80,000 miles. $104 for 3 seals and the sealed bearing that took about 2 hours of my time.

Replaced both rear ones @ about 70K miles. Had it doen at the dealer for ~800 with alignment (which is not necesary).
