[Closed] play in rear suspension

[#2284714]

hi guys,

ive just finished cleaning my trusty top fuel 8.
and whilst doing so i noticed that its developed play in the rear suspension.

its not much, only a few mil maybe 5. when you pick the bike up by the saddle/seat post, the bike lifts up and the back wheel stays on the ground and the bike lifts up.

does that make sense? i dont remember it doing it when i 1st got the bike.

do i need to replace the bushings/bearings? or is this nothing to worry about?

thanks in advance.

joe

get it sorted - as above - probably shock bushes but get it done before anything else gets damaged by the wear.

what year is it? I have a 06 fuel and have had no end of main pivot bearings working themselves loose. I believe I made it worse by not fixing mine straight away. If you have the slip fit bearings I have on my 06 be sure to use loctite 638 or something similar when you fit new bearings

If you let all the air out of the shock you may find it easier to move the back wheel about and find what's waggling.

As 'Bagpuss' & 'wwaswas' - it'll be the shock bushings/eyelets...

i have the same issue with my 2011 blur ltc, but the play doesn't seem to be coming from the bushings but the shock itself......

As others have said, if its a little loose up and down but nothing side to side, It's most likely the shock eye bush. Wrap your fingers around it and lift the saddle. You'll feel it then.

You could try putting your hand in different places and giving the back end a shake, try not to get it pinched or jammed anywhere. If it's just the inner eyelete bushes I have some DP4 compound ones I can chuck in the post to you for free!

You could also remove your rear shock and check how tight the bushes are by twisting them with your fingers, I would get it sorted right away.

good luck!

Maybe but probably not.

Onzadog has given you the correct and simple advice to check the bushings, no need to remove the shock.

I recently traced play to the actual shock, (old Manitou Swinger), the actual shock appears to have about 2mm play, worse when air pressure is lower.

When everything is tight there is a slight clunk when I lift the saddle, having spent ages pulling this and that (and getting independent help) I can 'feel' (vibration etc) in the shock when I hold the shock and lift the bike - it's like 2mm of travel is 'free' and it just clunks hwne the slack is taken up.

Maybe try pumping it up to a lot and seeing if there is a difference.
Can you mount the shock at one end and try for play.

Neil853 is it a HV can??? Had no end of set up issues with mine and in the end sent it to TF for a PUSH tune to suit my riding and weight.

HV? It's a 2011 boost valve RP23. Having said that I've just fiddled around with mine and it Looks like the bottom shock bush has play, after 2 months!!!!! This can't be normal? A dozen rides and now the shock bushing's need replacing?!

neil853 - Glad you got sorted out. HV = High Volume air can. Sounds like it's the same as I have but I just couldn't get the feel right on it hence sending it to TF. It's like a completley different shock now.

Also had a heavy duty shock mount kit fitted (15 quid or so)

hi guys,

got another update!

its not the bushes. the play is in the bearings on the pivots that the rocker link and swing arm are bolted to.

unfortunatley the bearings wont be in until after christmas!

thanks again,
joe

When you had the shock off your frame, did you pull at the different suspension parts in opposing directions?

Always a good way to check the bearings, too much stability with the shock on.

Ridefree! mate!!! ๐Ÿ˜€
