Just the bad one. There's no benefit in replacing good bearings prematurely. You're not saving time or anything. They might still go for years.


If the front is bad, just change both front ones.
The same goes with the rear one. 


Both bearings have the same miles on them so if one goes bad, the other ones is on its way out. If you don't want to go to a mechanic shop again ,do it in pairs.

No, the other one is not on it's way out. I've had bearings last for years after the other side went out. Bearing condition depends on so many different things that they never go out at the same time. It's not just my opinion, but that of experienced mechanics as well. I've seen bearings changed on trucks belonging to me and my friends, and the mechanics do not do both sides.


But let's say they did wear out within a few months of each other. You're not saving any time or money doing them together. It still takes twice as long.



Some bearings can cost $400 or more. So you're needlessly flushing a lot of money down the toilet.


Change both front bearings, the other one will have the same wear.
