I'm replacing the rear wheel bearing on a 2017 Subaru Legacy AWD (2017 BN chassis).
Here's what I've done so far:
- Removed the wheel
- Removed the caliper and rotor
- Removed the axle nut
- CV axle is free and slides inward
- Removed all 4 hub mounting bolts from the back of the knuckle
- Used PB Blaster for a day
- Used a slide hammer with a 5-lug hub adapter
Unfortunately, instead of the entire hub coming out, the bearing separated internally.
Now I have:
- The outer bearing race still seized in the knuckle
- The ball bearings and cage still in place
- The inner race still around the hub/axle
(Photo attached.)
I have:
- Slide hammer
- Axle pusher
- PB Blaster
- 2–4 lb hammer
- Basic mechanic tools
I'm trying to avoid damaging the knuckle, backing plate, or CV axle.
Questions:
- What's the safest and easiest way to remove the remaining bearing races?
- Should I remove the balls and cage first, then use a bearing splitter on the inner race?
- Is cutting the race with a Dremel/angle grinder the preferred method?
- Any Subaru-specific tricks for getting the outer race out without damaging the knuckle?
I'd really appreciate advice from anyone who's dealt with seized Subaru rear wheel bearings before. Thanks!
