I have a 2003 SGS Pro,
When I pull up on the seat or the seat mast there is a little play in the rear linkage....is this a common problem? and how do I fix it?

Sounds like the busings in your shock may need replacing.

its not the shock that moves...i should have been more specific....the movement occurs in the bottom of the shock where the bolt goes through to connect it to the linkage plates

What dave said will fix your problem. The bushings are in the eyelets of the shock. When they get worn out, play develops right where you are describing.

I usually replace the lower bushing twice a season.

That will fix it.

Also check the sleeve that the bolt goes through. I found that after riding with worn bushings on mine, the sleeve had crushed a tiny bit, causing some play even after I changed the bushings.

This is an anoying problem! I have the same thing on my bike. Multiple bushings later and it always comes back. Whats going on is there are two hollow rods that run from both E13 link plates and come together inside the lower eyelet in the shock. The problem is that those two rods are turned down (machined to a smaller diameter) with crappy tolerances. They are definitely a rough cut and not a finishing cut. If you ever compare them to the FOX pieces used to mount up a FOX shock you will see what I am saying, the FOX parts are smooth and polished.

If it's moving relative to the shock axle, it's the DU bushing in the shock.

If it's moving relative to the linkage plates, it's ovalized linkage holes, and you need new linkage plates. This happened with my 03 sgs and it was taken care of, to this date there's no play in there.

yeah, but the DU bushings will continually wear at an elevated rate, mainly because of the poor surface finish and the low tolerances on the hollow rod which allow dirt/mud to speed the process.

No, mainly because the manitou DU bushings that are on many of the SGS bikes such arse, at least as told to me by IH. My experience with the "hollow rod" backs this up though, my fox DHX and Prog 5th element had no bushing issues, but the manitou's seem to be pretty junky in comparission.

From the shock maker.
