Default Repacking Wheel Bearings

Repacking wheel bearings for my 1998 Mitsubishi montero sport V6 4wd vehicle. Never done it before, car novice with repairs. Anything I need to know? Any special tools needed other than ratchet and socket set, and wrenches?

Thanks

I was just looking into wheel bearings for my '02.
Except for my model the bearing can't be repacked.
The wheel bearing comes as a complete sealed unit you swap with the old one.
I'm not sure about your year and model. Make sure you check your factory manuel before diving into the project. Sometimes a call to your local dealer can be helpful.
Good Luck

Well I didn't know that. The dealer quoted me $244.28 to repack the wheel bearings. Were they lying? Or is there something i'm missing.

Why do you think your bearings need repacking? Is there evidence of grease leaking out of the hubs? Spending a lot of time driving through rivers?

Nowhere in the service interval chart for my '99 does it mention repacking the bearings even though it mentions almost everything else. Maybe I'm living on the edge but my bearings are just fine at 208K.

With 4wd getting the front hubs off requires special tools to remove and a viariety shim packs to get the spacing right - especially if you mess with the bearings - the so it's not a DIY job IMO. If you feel you really need new grease have it done by a mechanic.

I've talked to alot of people and they say the unit is a sealed unit. You cannot repack the wheel bearings. It only came to my attention when I had to get a engine diagnostic done to my vehicle when it wasn't starting (due to the camshaft and crankshaft position sensor). They said they should be repacked along with the cam plug o-rings.

I've owned three 4WD/AWD Montero Sports and none of them had sealed bearings. The only time I've ever repacked them was during the R&R of the brake rotors where the hub has to come off anyway.

You are going to need a special tool to remove and properly preload the jam nut that holds the hub on. Mitsu sells the tool but it is very expensive. I made mine by modifying a Chevy front hub socket (I had all the teeth milled off except two directly across from one-another). Do a search here and on http://msport97.proboards.com/index.cgi? for more on how to make one of these hub tools. Some people use a punch and hammer to tighten and loosen the jam nut but that is a ghetto solution that won't give you an accurate preload for the bearings and will likely damage the nut.

Replace the seals too. They are cheap so you might as well while you're in there.

It's likely that when you called the dealer you were not speaking to an actual mechanic. The service guy most likely looked in the computer for a price quote for repacking wheel bearings without bothering to plug in your year vehicle. It's sounding like the wheel bearings have not presented too many problems for people. My research says that the front units are over $300 per sealed unit and the rears are over $200 per unit.

No, my vehicle was physically there. They did a complete maintenance check on it.
