    Epic Suspension Pivot Bearings

    My 2012 Aluminum Epic is been raced for the entire season and is a little tired and in need of some tlc. I pulled off the shock to send in to be rebuilt and I pulled off the s-link to get the brain hose out. When I spin the s-link bearings in my hand, I can feel some notchiness in the bearings. I do not detect any play in the rear triangle and the suspension does not make any noise when I cycle it through its range without the shock on.

    Is it time to start replacing bearings or is there another season of life left in suspension bearings. When does everybody else start replacing bearings. I should note the bike has been raced in rain and mud along with the normal baths it received during the season.

    I am new to the mountain bike thing so I am trying to learn what proper maintenance is for a full suspension mountain bike that is raced pretty hard.

    Mine just had a birthday, all pivots pulled apart, etc. The mechanic just popped the seal off the bearings and re-greased as they were dry. Assuming they are ok can't see why you would need to replace?

    You may be able to regrease them, but if the bearings are notchy because they're pitted, then it wont help much. Notchiness is a sign that they are running low on grease, and if left alone will seize up.

    With winter months coming, I probably wouldn't replace them now. Wait until late spring after the trails dry up a little bit post-rain/snow season.

    If I am going to re-grease the bearings, how do you pop off the seals?

    I pull all of the smaller bearings out when I send my shock back for a rebuild, the larger ones will get inspected and tested, but if yours are "notchy" that means they have been pooched out.... somebody overtightened the bolts that hold them in.... the torque specifications are printed and included with the bearing kits....

    If the bearings are notchy, then they are shot. Replace the bearings (any engineering show will supply), and re-grease the bearings every 6 months or so (pop the seal off), especially when the bike gets wet often.

    I've done this once so far on my 2011 - I believe that the OEM bearings are pretty dry when fitted...
