My '02 is turning 55k on the original rotors and starting to wonder when the bearings may need a repack - is there a factory recommendation for mileage on the OEM bearings? All's quiet on the forward front but I hate to tempt fate ...

 

None that I am aware of - usually do it only whenever I do a full brake job where the rotors are turned.

I suggest that at 55K, you have at least that many more miles to go before worrying too much about this, unless you have an unusual event such as a brake dragging that significantly heats things up, a 'through the river and into the woods' expedition, etc.

Also, you can see my generation truck in the sig, so I'm not totally up to speed on the newer stuff - are you sure that your generation doesn't have the sealed bearings???

 

Yep, you have sealed bearings. when they go bad you just replace them. they are kinda salty though.

 

The bearings on your truck are not serviceable. If you want to do some preventative maintenance, you'll have to buy the entire hub/bearing assembly.

are you sure about that hub/bearing assembly replacement? I thought the inner/outer bearings could be replaced or repacked just like any other typical setup -

4x2 s-crew sport....

 

On a 4x2 you may be correct. On a 4x4, I'm certain you cannot service the bearings. I looked into this at one point because I was going to repack my bearings. I assumed your truck was a 4x4. My apologies for the confusion. You may want to search the site. I'm sure there must be some additional info on a 4x2.

4x2 03 here, and yes you can repack the bearings.... I did mine at 30ish when i did my brakes to begin with, ill probably repack them again soon.

I need to turn my rear rotors now too. Ill investigate the bearing situation back there while i have it torn down

oh yea im 51xxx.x now

 

i have a 99 4x2 with 110,000 miles...i just recently put a 3.5 spindle kit on. When i pulled everything off, i found the cheap plastic bearings...i suggest replacing them as opposed to repacking and reusing...

 

appreciate the feedbacks - makes sense the 4x4 would need a hub - my bad for not specifying...

I may just replace rotors and bearings together - would probably still be cheaper than paying to machine the OEMs by the time it's all added up...

- gotta luv this site!

 

well i machine mine for free at school, but i believe Oreilly machines them for 5 or 10 bucks a piece off the truck, and bearings removed.

No O'reillys here in the Orlando area that I know of - probably a NAPA machine shop or some other local but haven't checked yet. Have heard great things about them though...

The OEM rotors would be good spares to turn after new ones wore in, I just hate breaking up the day running from place to place when my main ride's up on stands... Much easier just to have everything in 1 place

 

Can't argue with having everything at arms reach.

My Manual says to repack the bearings every 30k miles. HOWEVER, I had 120k on mine when I did it. I do not know if the previous owner had it done or not, but, from the looks of things it wasn't done. I have had it since 80k miles. I like to replace the whole shebang when I already have it apart.
