To answer the original question...

...service shocks and forks that see "average" use every 20,000 ks.
If used in anger (competition, hard riding) perform more frequently, same as other maintenance.

WP top bush

Top bush in my WP shock is showing wear, do I have to get it pressed out or can the job be done easily. Thanks

I noticed that if i hold the nitrogen container with my hand I can move it right and left for a cca 3mm, it is not the container that moves, it is the whole shock&spring....that does not seem right to me.
Could it be that the bearing on the lever link is shot? Or do you think it's something else...bushings....?
And, yes, I checked if all the bolts and nuts are tightened.

Makazika: I noticed the same thing when adjusting the rear spring preload. My understanding is that the top mount of the rear shock absorber utilizes some type of ball joint, which brings a certain amount of "flex" or "play" into the shock mounting. However, I am uncertain as to exactly how much "play" should be considered allowable.

Tseta, I might be wrong but this is what i got from a local forum on the topic; it's normal to have some play on the top mount of the shock and they say that the indication of a shot bearing would be increased play of the swingarm (up-down), before it gets into contact with the shock...

Later today I'll measure the play of the shock and the play of the swingarm so we can compare values...

Z-dog , everyone,
Here is the Mongolia shock along with my sprockets which were lubed using a Proiler.
The oil on the shock, AFAIK is from the Proiler, the shock was working fine when removed and was certainly no pogo stick, I ripped through the Austrian Alps after doing Russia Mongolia and the East block, the bike was shipped to Nova Scotia and ridden back to Wisconsin. To start the trip it was ridden to Seattle from Wisconsin and freighted to Russia. My front suspension was a non-issue, I used Z-dogs shim setup and Infinity sub tanks, a Scotts steering stabilizer, the bike was lowered around 4 inches.

It is the best all around travel bike setup money can buy IMHO.
Next week I will be sending the shock to Z-dog for service.
The total mileage was close to 16 K.
Note the original spring and the heavy preload wind necessary for the panniers and luggage I carried.

Here's a picture of the bike in Germany after being ridden across Russia and Mongolia.

My shock turned pogo on me just one week after returning from Morroco !
I think it held out till I got home ........

Its an 06 with 16k and it turns out it was dirt in the seal and not wear and tear

IMO I would rebuild every 5k for the sake of 80 or $

If the shock and forks are unknown then rebuild before any long trip ...

I have had shocks and forks rebuilt only to fail one week later due to me allowing mud to dry on the stanchions and shock shaft and killing the seals ....

Clean them often ....
