Hello guys, i thought i might get some help around here
since lots of you know most about MTB and suspension.

I have a swinger 3way AIR. Just serviced it and now
it feels alot better overall. But the thing is that the
Rebound damping only works during the first 2/3 of stroke.

At the end of the stroke the rebound is nothing and
the shock is topping out with a top out clunk.

I tried now 4 times to bleed it as my idea was that
it was air trapped in the shock making the rebound
damping work only part of the stroke.

I put the damping part of shock togheter SUBMERGED
in oil as servicemanual says. And i stroke it a few times
to remove airbubles, and tap it too.

It is lubed with slick honey and filled with 5wt oil acc
to spec.

PLEASE POST YOUR IDEAS! i really like to get this thing
togheter now.

PS. service manual says "failure of negative spring, replace
aircanister and seals"

But this problem occurs in the damping assembly only, it
is clearly noticable even without mounting the air canister
and pumping the air spring.

HI kebarb,

it´s a strange problem indeed...
wouldn´t you mean bottom out noise instead of topping out?

but wouldn´t it go away if you assembled the air can, as it has the air making it extend?
did it extended fully without the air can, before servicing?
the damper shaft may not extend fully when the air can is used...so that you dont hear the noise when mounted...
have you checked for parts like orings that you forgot to mount?
has the spv side enough pressure?
i´m a bit sleepy so i´ll have a read at this later, so i can think about it clearer...

if no one else replys, why don´t you ask at mtbr forums(shocks forum)... ?

Check your IFP pressure. Without enough pressure the SPV will hang open and provide no damping. Only after the shock has compressed and the pressure risen enough will it close. Old pumps are sometimes the culprit of this.

^^ thats most probably your problem. if you pressure is alright then you got a sticky control valve.
