Greasing front sealed unit bearing hub

Have any of you tried adding grease to a sealed front unit like found on a 2000 Jeep Cherokee. If so how did you do it and did it work. Any advantage to doing it?

Re: Greasing front sealed unit bearing hub

I have done it on stock hubs with the rubber seal--just pop the seal out, clean the bearings with brake cleaner, pack them up again with wheel bearing grease, and tap the seal back into place. SKF hubs have the rubber seal too, one of the reasons I buy them for replacements. All the others I've seen have steel seals that are too difficult to remove without damaging them.

Re: Greasing front sealed unit bearing hub

Mine's a 96. last summer a brake caliper seized tight enough to bring
smoke out of the fender well. Caliper issue has been solved, but I've been
worried about the wheel bearing and if the grease has been compromised?

Is it worthwhile to change out the grease (if possible)?

Dont think they're serviceable. Comes out as one piece and looked like a PITA to disassemble, although it's been a while since I looked at one.

Re: Greasing front sealed unit bearing hub

I'll probably wait until there's a reason to change
it out then. It's not leaking grease or making noise.
Thanks for the response.
