Hi guys bought a second hand Trek as above about a year ago and it's been fine, recently though the rear end seems to be clicking / creaking a lot. I checked the headset bearings this morn they were smooth so just re greased and put back together. Don't think its the BB or pedals as the noise happens when i compress the suspension while i'm not on the pedals also pretty sure it's not the seat it's an i beam and is in good nick. What i noticed yesterday is when i sprayed GT85 on the pivots after it had penetrated this seem to stop it. This was short lived though as the noises gradually came back. So where do i go from here ? do i need to strip the rear suspension check the bearings and re grease or am i missing something. any tips for servicing. just any help really. Could it be the rear shock. (RP2)

    sounds like a full service is needed. I would get the shock done at the same time as the rear end is overhauled.

    Ok i'm pretty good with this sort of thing so where would the best place be to get service parts. By the way no play in the re end so would i still need to replace the bearings

    I had the same problem with my bike....drove me nuts for about a month. I rebuilt my rear shock, put in new pivots, new seat, new seat post, nothing worked! After researching the problem on the internet and bugging Trek and my bike shop I finally found the problem.

    There is a bar in the down tube for the seat post, almost to the bottom bracket. You will see it taking your seat, seatpost out. Shine a flashlight down the tube get some triflow and saturate that bar. Worked for more noise. Hope this helps!
