Start with your bike on a stand with the subframe and shock absorber removed. I removed the rear wheel for video purposes, but you do not need to.
Remove the lower chain roller to make room for the frame side connecting bolt.
Remove the side collars and seals, followed by the inner bearing races. The inner races should slide out, but they won’t, so find a socket that fits over the inner race only and drive it out.Remove the old needles.
Removing the outer bearing race requires a blind bearing puller. If you don’t have one, don’t bother buying one because they won’t budge anyway if they are contaminated. That’s why I went straight to the heat and beat method to remove them.
The outer bearing race consists of two separate races mounted on each side of the bore, with a gap in the middle. This means you need to heat and drive one side in slightly to break it free, then drive the other side into the bore, to drive both bearings out the same direction.
You may need to get creative with your sockets and clamps.
On the 1997 model year, the link bearings are mounted in the frame, and the 1998-2001 models have bearings mounted in the link, which makes more sense. If you have a 1997 model, you will need to take extra care when you heat and beat the frame bearings because the angle of attack is not square.Clean & Inspect:
Clean your linkage parts as thoroughly as you can and inspect for damage.If the link is damaged, it will need to be replaced. If the bearing bores are damaged, do what you can to smooth the surface. Due to the bearings used in the linkage, you should be fine unless the bores are cracked or broken.
For this service, I am using an All Balls complete bearing kit.
These bearings are designed with a very thin outer race, so if you try to drive them with a hammer and socket, the chance of damage is very high.
These bearings need to be pressed in using a hydraulic press or a bolt and nut press. You can buy a proper bearing press kit for $150, or you can make one for $20 out of grade 8 bolts and washers.
Before you install the outer bearing race, remove the bearing needles, and set them aside.
I like to insert a small socket inside the bearing race to help with alignment, but some aggressive adjustment is usually necessary. The thin outer race is very forgiving, so hammer adjustments won’t hurt it, just don’t go crazy.
The bearings in the swingarm bore, in the frame on 97s, and the shock link on 98 to 02s need to be driven into the bore 4 to 7 mm.
Press the shock link bearing into the bore 6 to 7 mm.
Press the outer race in like the others, then carefully drive or press the race to the center, measuring as you go.
Carefully install the needles in the bearing race. They should be coated in a light layer of grease from the factory, so they stick together in the bore. If your needles aren’t sticky enough, some white lithium grease will do the trick. Your needles should sit evenly with no gaps.
With one side done, install the inner pivot collar to keep them in place as you do the opposite side.
With both sides assembled and the pivot collar in place, secure the assembly with a zip tie.
Apply a thick layer of moly based grease to the bearings.
Remember, there is a gap between the bearings, so get as much grease as you can between them. Work the grease around the bearing into the needles, but be very careful. If you pull away from the bearing like this, the needles will stick to the grease and come out. So work your finger around the needles, then slowly slide your finger out of the bore while keeping pressure on the needles. Grease each side, then install the seals with another coating of grease, followed by the pivot collar.
On the widest bore, install the two large washers, followed by the seal and pivot collar.
When installing the linkage assembly, make sure the shock arm is oriented correctly, with the small end facing forward.With the link attached to the frame and the arm attached to the link, swing them around to make sure everything is rotating smoothly.
If everything feels smooth, attach the shock arm to the swingarm.
