Default Replacing wheel bearing on 98 Outback?

I am thinking about picking up used Outback, but the seller says front wheel bearing needs replacement (as well as fuel pump). I've replaced hub assembly on Miata, but not sure what is involved in replacing wheel bearings on Outback. Lastly, can WRX fuel pump be used on 98 outback? I have a spare WRX one which I replaced with Walbro.

Thanks guys!

wheel bearings need to be pressed in and out.

fuel pump, is easy enough, take out the unit, replace the pump, but the unit back in. I wouldnt put a wrx pump in an outback though.

I have searched, but only found wheel bearing relacement on WRX. I am assuming Legacy and WRX wheel bearing replacement are similar.

I plan to do this myself and just take the hub assembly to the shop with press (NAPA or local shop). Perhaps I can get everything done under $100.

pretty much the same as the WRX. Most DIYs take the hubs/knuckles off and them bring them some place to have the bearings pressed in and out.

Only tough part on the older cars is getting the kunckles off, the lateral links bolts tend to seize in the making it pretty much impossible to get them out without breaking or cutting them and sometimes damaging the bushings.

The wrx pump will work fine, a little more flow but that never hurt anything. I think they even use the same connectors.

with the wheel jacked up in the air, can you move the wheel by grabbing it from top top bottom? is there play?

That test isn't 100% valid; sometimes the wheel won't move even if the bearing is shot.

Also, I doubt the OP knows if the wheel will wiggle. He's asking about a car he's thinking of purchasing, not one he's inspected. lol

you are dead wrong on this. the bearing can be junk and without causing any play in the wheel. sometimes you can hear the roughness in the bearing while the wheel is turning but there is no side to side play.

I wasn't disagreeing I just want to know how to know if bearings are shot if the "rock it" test comes back good.

The bearings are kind of a pain. You have to pull the spindle off and press them in/out in a press. I usually just buy a complete used spindle/hub/bearing and put that in.

The fuel pump in the wrx has a controller to lower the output at idle. In theory you would need that to put it in. With that said, I used my old stock wrx pump in my brother in laws outback sport when his pump went bad. It just fit and I did nothing else but bolt it in. It runs fine and has been in there for at least 6 months and 10,000 miles.
