How often do you repack/replace wheel bearings?(5 posts)

How often do you repack/replace wheel bearings?chipnseal

I have 2 bikes, one with Shimano 105 hubs and the other with Ultegra. Both have around 4,000 road miles on them. (Dry, too, by the way)

The bearings sound OK, but am I missing something? I've been doing more and more of my own maintenance lately since I bought Zinn's roadbike book.

Any recommendations out there?

It varies. If I've ridden in the rain, I'll pump my AC front hub full of grease. AC hubs have a greaseport. I'll pull apart my Campy hubs just once over the winter to check them out. I usually do about 3-4000 miles per year but I use two different wheelsets.

After 4000 miles, I would repack the hubs. Its' only a half hour job, so go for it.

And isn't it fun to do your own wrenching??

I would say that I repack hubs at most annually. Much less frequently since I stopped riding as much. I would say that 8,000 - 10,000 miles is frequently enough. Generally I would replace the bearings at the same time.
Roughly, oh . . . never. But when I do...cory

I spread the wear around on a number of bikes, and I haven't ridden anywhere near as much as I'd like to the last 18 months or so. I think the most recent repack was two years/1000 miles ago on the singlespeed. But my backup mountain bike, now used mostly in the mud, is eight or nine years old, heavily used for five of them, and never been touched. It needs it now, though.
As a rule, I give the wheels a spin when I think of it and hold my hand lightly on the hub to feel for vibes or roughness. If I feel any, then I service them. I usually replace the bearings, not just repack. They're so cheap in bulk ($2.90 for 100, I think, last time I bought them) that there's no reason not to.
about every 5K milesDaveG

I don't know if 5K is a good mark or not but I have not noticed much degradation over that time (mostly dry riding). Its not that hard to do although getting the bearing tightness just right can be frustrating.
