Front hub question
Hi All,
My ABS light has been on and I am finally getting around to fixing it. I discovered the front left sensor broke. When I removed it, part of it stayed lodged into the hole. When I tried to get it out, it fell into the hub and I can't get it out. Coupled with the fact that the bearings feel bad, i am going to replace the entire hub assembly. Do these come pre-packed with grease, or do I need to repack before assembly?
Second question: the other wheel feels fine, but should I remove and repack the bearings on it? Can you just remove the ABS sensor and apply grease through that hole?
Thanks,
Steve

I believe this depends on 2wd or 4wd. The 4wd assembly comes as an assembly, the 2wds have the option of just replacing the bearings but I think I've seen units too.
If you do one, you might as well do both so you know when each was serviced and the intervals should be close on them.

The 4wd hub is not supposed to be serviceable. I've heard of someone trying it and not being happy with swapping the bearings out. The hubs I've seen come with new ABS sensors and pigtail.

I haven't replaced a hub yet so I wouldn't know if it is prepacked, but it should be. If not they are not hard to pack.
Use guzzles site to service the other side so like Reax said you know both were done at the same time. He refers to them as the needle bearings. Might as well service the esof hubs while your in there. While I was in there doing the maintenance I also upgraded the brake caliper pins to the new ones, again guzzle has all that info on his site.

Hello Steve
I just replaced mine from both side. You need to change the whole hub.
You need the yellow o-ring and might new bolts ...

And if your brake rotor is bad, You might need to change that too. I had to, because they did not even come off from the hub - rusted to one piece.
Here is a good page with pictures how to do it:

I ordered new hubs through my work from Federal Mogul. They are National brand name, (National Seals) and came with the studs, some brands don't.

Thanks for all the replies. I just finished. The new hub was pre-packed, but I added some more anyway. I pulled the other hub but it looked new, I think it must have been changed recently (I've only had the truck 1.5 years). Pretty simple process, I hope the new hub lasts awhile though.

I was talking to a mechanic about this yesterday. He said a truck came in and the guy wanted a new hub installed on his 250. He tried twice to replace just the bearing that was shot himself but each time it failed within a month or two. Funny thing was is that he took the failed bearing back to the auto parts store and tried to get warranty out of it. They wouldn't warranty it cause the hub is NOT supposed to be serviced, only replaced.
