Will this work on sealed wheel bearings?

Yes, three-leg pullers in this set are designed for sealed bearing removal. Two-leg pullers handle inner races and tighter spaces. Test-fit your specific bearing first to confirm jaw clearance.

Do I need any other equipment to use this set?

You'll need a breaker bar or wrench to turn the center screw on each puller. A hydraulic press makes the job easier for larger bearings, but this set works with hand tools if you have time and leverage.

What if a jaw doesn't fit my bearing?

The 14-piece set covers most common passenger vehicle and light truck bearings. If a puller jaw doesn't grip cleanly, stop and use a different configuration from the set. Forcing a mismatched jaw risks slipping and bearing damage.
