'''Caution:''' There are better/safer ways to do this than shown here. Use EXTREME CAUTION when supporting the bike in this manner, or serious injury could result. Ideally, someone to steady the bike would have been helpful but 'cheap labor' was not available for this article.

'''Please note''': This service should be done at the same time that the [[Servicing the swingarm|swingarm lubrication]] is performed, but the trained monkey was asleep at the wheel when his swingarm service was performed, so 7000 miles later here we are. If you are going to do one or the other, do the unitrak first; it sees much more of the elements than the swingarm, as the pictures below seem to show.

11) The Service Manual shows an outer sleeve (bushing) around the inner sleeves you just removed, but it seems unnecessary to remove these for 'normal' service. Even with as bad as these were (you'll see) the bushing cleaned up nice and smooth, so they were left in place.

12) Once the sleeves and seals are out, it's time to start cleaning. Here is where the supply of towels and kerosene come in handy.

23) Once the bike is on the centerstand fully, remove the floor jack.

24) Tighten all of the linkage nuts you can get to to ~~33ft~~ lbs torque. You may need to put a wrench on the bolt head to hold it. One of the nuts, and maybe more, will be blocked by the centerstand. For these, put the bike on the sidestand to finish torquing.

25) Reinstall the mufflers and passenger footpegs.
