[Closed] Stuck down shock Help!

Had a lovely ride this morning on my just rebuilt Enduro. Right up to the moment the rear shock stuck down.

Its my own fault (probably) for not having it serviced after two years of no use at all.

So the question is, is there anything I can do to fix it? I am confident doing air can service etc. Or should i just post it to mojo or tf tuned and deal with the bill.

Or plan 3 buy a new shock with all the new advances in damping etc.

Current shock is float r with the itch switch (04 enduro)

Send it to loco tuning , a mate had it happen to him a few years ago , tried to do it himself and got a nasty hole in his hand .

Usually down to a leaking seal, DO NOT ADD MORE AIR!. Can be done at home, but much safer to leave it in the hands of a specialist, they can let go with a hell of a bang sometimes.

Thanks. I thought it had leaked and pumped it up again. B*****r.

Sounds like a job for the pros then. Although mystified by how you hole your hand I dont want to find out first hand!

Universal advice seems to be that stuck down shocks have a fair bit of pressure in them and taking them apart if you are an amateur, however gifted, may not be a brilliant idea. I had this problem last year and Mojo sorted it out by return - mind you that was in warranty so no issues with cost and as a warranty claim I wasn't going to fiddle with it myself anyway.

Fox does have some advice on their website, but basically say if it is stuck down then send it in. There are easy to find procedures for checking and dismantaling but all seem to stress the possibility, and need to avoid, turning the air can into a projectile. Loco contributes to the forum and may be able to offer more advice and I have found both Mojo and TFTuned extremely helpful on the phone in the past.

I had this happen (at very low temperatures) out on a long ride once. I had to open and reset it in order to get home. I found that leaving it attached to the frame and wrapping it in a jacket while I unscrewed it did the trick. Still bloody loud when it popped off though.

Check your pivots that none are sticking, my shock stuck down and it was due to this as it puts the shock through un-natural forces so it bonds to itself internally somehow.

I've had a stuck down shock (low temps 4 years ago). Take it off the bike, rag fed through the bottom eyelet so that when the air can lets go it doesn't fly across the room (the rag stops it).
Then do an aircan service and replace the aircan and body seals.

Too much air has gotten into the negative side of the shock, this is what's trapped in and cannot be released. So you basically have a little bomb on your hands. Like bigyinn has stated if you gingerly remove the air sleave with a rag in the eyelet wearing earmuffs and goggles you then can do a air can services once it pops off. If this idea scares you get someone else to do it. I did such a services in a open plan workshop and it made everybody jump in the shop when it let go.

n't think he knows much about what he's on about but the advice on how to split the shock is sound enough....[/url]
It's a simple enough job
