its a 94 pu 4x4 and i'm in the process of replacing or repacking the wheel bearings. i've removed the rotor and hub assembly and now the chilton manual says to "pry out oil seal and remove inner bearing" (i hate these bull shiv sm's that are so vague with such awful pics and no diagrams when you need em! i don't know these parts by name mr. chilton! thank god i'm only 1/2 retarded) . with what do i use and how do i do this without damaging this oil seal? thanks in advance

In my humble opinion oil seals are not a reusable item. They're cheap to replace so just pry it out and get a new one. No point in doing a few hours worth of work, finding out the seal is leaking and having to do it all over again.

yeah there like 5-8 bucks depending...and you allmost allways mess it up taking it out...i do anyway..

If you want to try and reuse the seal, remove it as follows.

After you have removed the outer bearing, washer, nuts, etc., reinstall the washer and one of the nuts onto the spindle. Then firmly grab the rotor/hub assembly and slide it over the nut and washer until it contacts the inner bearing. Then pull hard, hitting the bearing against the washer, and the seal will pop out.

I've used this method many times, and it works like a charm. Make sure to clean and inspect the seal before you reuse it. If it's worn, go ahead and replace it.

Good luck.

ok, so am i supposed to just stick a screw driver in there or what. more emphasis on the "how" and not so much on the "without damaging it" also, how can i tell if i need to replace the bearings or just repack them. with the wheel on it wiggled a little but not a whole lot like i've seen others

mapple83

you lost me at "pull" do you mean push? maybe i'm not understanding correctly

You are using the washer and nut to push the inner bearing and seal out of the rear of the hub. So, pull. You are holding the rotor at 9 o'clock and 3 o'clock when you do this.

what is keeping the washer and nut fixed on the spindle?

You really can't. Just get new ones.

The nut is threaded onto the spindle.

Not true. I did this last time I repacked my bearings. I don't recommend reusing 15 year old seals. However, if you had recently replaced the seals, and say drove through some deep water, it wouldn't be a bad idea to try and reuse the newish seals when you repack the bearings again. I personally don't want to spend the money on new seals every time I service my hub bearings. Maybe I service my truck more often than the average guy though.

You can most DEFINETLY re-use the seals people. Holy c'moly.

You get this repacking thing down to an art form when you use your rig in high water a lot. You think you're gonna go ahead and replace every seal everytime you contaminate the bearings with water??? i dont think so

If you're diving in to replace parts and not just do "maintnence" then ya replace if it is old or damaged but if its fine, its fine. You can remove it easily without damaging it.

Saying it can't be done or it HAS TO BE REPLACED IF EVER REMOVED. Is inaccurate advice.

drew303

And as for the HOW part, Just drive the bearing down onto the seal and give it some motivation and it will drive the seal out without damaging it.

Which is exactly what malteserunner is suggesting how you do it.

Sorry to repost on such an old thread, but I've been trying to find some advice all over on this. My problem isn't that I want to re-use the old seal... I can't get the freakin seal back in the spindle. I've got the bearings all packed and am using the 54mm socket to try and hammer the seal back in, but I'm not having any luck. I did the wheel bearings a couple years ago and I remember it took me a while, but I'm not making any progress here. I've also used a wooden board to lay over the seal flat and hammer that way.. but no dice.

Does anyone have any suggestions for me on getting that seal back in there?

2x4 laid flat (like this __) over the seal laying on the hub body, then using a hammer to tap it in. Put the hub on a piece of plywood or 2x6 to avoid damaging the front face.

Thanks man.. I'll definitely give it a shot. That is one of the most awesome diagrams I've ever seen haha.

I tried the method mentioned bracing the axle hub and rotor with the nut. The washer is too big to fit through all the way to the wheel bearing. But the nut prevents the hub from coming off when I pull on it a 9 oclock and 3 oclock. I must not be strong enough to pull it off this way. How would I setup a autozone loaner bearing puller to get the oil seal out?
