You only get around 5000 miles out of a new set of rubbers they become compressed then start to break up, the excess movement allows the rubber to twist & this causes them to break up, the sprocket carrier then has lots of free play, which makes the bike surge & feel snatchy at low speeds. Once they have become compressed they don't really shrink much more, so the free play needs to be taken up.

My fix is very simple, I have never needed to replace the dampening rubbers on any of my XT's even with my last XT doing over 20K miles.

If the rubbers are in tacked & not breaking up you can take up the free play using a inner tube rubber strips. By cutting 4 strips & laying them over the dampener rubbers then push the sprocket carrier into the wheel hub, this will fold the rubber strips in half & rap them around the sprocket holder & between the rubbers. You cut each rubber strips to size so they can rap over the sprocket carrier to size. You can use different thickness rubber tubes or double them up to take up the free play, go to a bike shop & get an old inner tube from them. You want the rubber strips tight, you need to apply alot of pressure to get the sprocket holder to into the wheel hub, using both hands push like hell on the sprocket from side to side & the rubbers will fold in half & slip between the rubbers & go together. Do not use any lube to get it together, the lube will damage the rubbers.

I would recommend one to do it around 3500 miles so the rubbers are still in good condition & you will never need to replace them & you will always have a tight sprocket Holder.

Yep I can confirm this works a treat, mine were shagged by 2500miles iirc.Now done 8500 and no play.

I've experimented with various packing materials but cut up inner tube woks best.

I'm swapping tyres often so I repack now and then with fresh strips of tube as the hub carrier comes adrift and rubbers tend to all fall out during tyre changing.

Cush drive rubber

When I recently removed back wheel ready for tyre change the cush drive just fell out in 8 bits. But I just put them back in the right place packed out with old inner tube. Nice n tight now. Wow what a difference! So much smoother around town. :blob1:

11500miles and I've ordered new rubbers...�29.35 ouch.

On the plus side my aftermarket chain fitted at 6000miles hasn't been adjusted once so the cush drive is worth something.

The original chain was very ****e quality imo.

Maybe a stupid question, but what is a cush drive?
I tried to translate it to dutch (interglot.com) but it doesn't seem to work.

Hope someone has a picture of the part fitted.

here's the proper translation:
de rubbers waarmee je achterste tandwiel wordt vastgehouden in je achterwiel.

;)

Mine were replaced at 10.000km, with the service under warranty. Now, at 24.000km's, the rubbers are still okay; kinda strange, 14.000km's compared to 10.000km, maybe the original rubbers are of lesser quality as the replacements? It also could be that the chain and sprockets were replaced at 18.000km, that the rubbers are still doin' fine? Anyway, I'll do the Kev mod with the innertubes, sounds good to me.
Thanx, Hans.

My original chain and cush rubbers were replaced at 11.5k miles. Apparently there was virtually nothing left of my cush rubbers and my chain had a really tight spot...combined I had pretty much stopped filtering as the bike was not smooth enough to be confident doing it. Low speed handling was getting pretty apalling.

I'm now at 19.5k miles and had my cush rubbers changed with a new tyre but I almost need not have bothered as they still seemed in fairly good nick. Chain still looks like new and has not needed any adjusting (DID X-ring chain and scottoiler fitted since bike was new)

I used talcum powder - seemed to make everything glide together. :whisper:
