Like the title said. A guy at my work said you need to pack your bearings twice whenever you change your rotors. Is that true?

 

I don't think so, don't quote me on that though. My friend asked about his '01 4x4, and as far as I know, they are sealed. I haven't had to ask the question on mine though since it's an '09! (yeah me!)

 

The 2wd aren't sealed. If you remove them might as well repack them.

 

Meh, I wouldn't mess with it. Don't think Ford does that with the new rotors on every vehicle

 

Might as well, its easy and will keep your mind at ease about one less thing. Good maintenance I suppose.

 

After about how many miles are you suppose to do this?

 

If you packed them properly when you installed them with the new rotors, then there's no need to "repack" them.

If you need to replace the rotors due to premature wear or something, but the bearings are still good, a little repacking then wouldn't hurt then.

But to answer you OP question, no.

 

id do it just because you have it all taken apart. its real easy. i see no reason to do it twice though.

... but wouldnt you need to replace the bearings unless you are swapping the races over?

 

on all my 2wd i repacked my bearings twice a year once in spring and once in fall.. could be considered over kill but i never had a bearing problem...

 

yes bearings and races are matching never supposed to put used races with new bearing or vise versa

 

im going to go with everyone else on this, if you have it all apart it only takes a few minutes to repack them so it would never hurt.

 

I'm going to go out on a limb here....a prety sturdy one......and say that the OP is asking if the wheel bearings need to be REPACKED AGAIN after installing new rotors. Meaning after the install and everything is fine.......to go back take everything apart and repack the bearings a week, two weeks, a month, or 6 months down the road......never gave a real good clear explanation there. Seems a few have missed that point.

The answer is no there is no need to do so. Next time you do a brake job you can check your bearings. If your dust covers are good and no dirt or water got in, your grease should be good.

If you like Redneckstone and like to do it twice a year, then go for it. Whatever helps you sleep at night I guess. LOL

 

Thanks for the responses! I went up to big 10 and had them check my front end. Looks like my rotors got warped a bit some how. So I'm going to have hit up autozone for my warranty.
