Some of you may have read that I have a clicking issue with the rear of my Trek.

Whenever I lift the bike by the saddle I get a click, when the shock compresses I get a click.

Earlier I let the pressure out of the shock and cycled it up and down, no click.

Put it back to the correct pressure and the clicking started again.
I guess this is bush related.

I am going to kill myself if I don't get this noise sorted as it is annoying the hell out of me.

I have removed the old bushes and they look OK but I will replace them anyway.

Now the dilema, they are 39mm long (gap in frame) but i can only find 37.4 or 40mm kits.
Anyone else fitted new ones if so which size did you use?

sounds like you've removed the mounting kit rather than the bushing.
The bushing sits inside the eye of the shock and the mounting kit then attaches to it with a bolt through to secure it up. The fitting kit is either a "top hat" arrangement or as per the TF Tune heavy duty fitting kit

I'd suggest your bushing need changing, not your fitting kit, as they are the sacrificial part in the equation (unlesss you've already done them).
you need a 1/2" bushing for fox shocks.

Yeah, sorry didn't phrase myself too well.

Fitting kit has been removed and noticed no real damage to the bush.

However, are the replacment bushes slpit bushes(have a cut in them) to allow them to mount as the ones currently fitted have cuts in them.

Sould I buy just the bushes (pack of 4 for £10) or the full fitting kit?

Did you just replace the bush or go for a full kit? If so, what size did you go for 37.4 of the 40mm wide kit as the gap is only 39mm.

[i]Fitting kit has been removed and noticed no real damage to the bush.[/i]
I've never found the damage to be visible to the naked eye, even compare new to old directly. You know it worked because when you fit the new one there no movement..

[i]However, are the replacment bushes slpit bushes(have a cut in them) to allow them to mount as the ones currently fitted have cuts in them.[/i]
depends on the material of the bushing, in the TF link the pcitures have a polymer DU bushing with no split and a metal with platic coating(?) which has the split..

[i]Should I buy just the bushes (pack of 4 for £10) or the full fitting kit? [/i]
I'd suggest just get the bushings, but as they add a P&P charge ontop it might be a good long term move to buy the mounting kit too.. but I'd try just replacing the bushing first even if you do buy the mounting kit.

Are you happy with replacing the bushing, or taking it to a shop to have it done?
The bushing tool make the whole job a breeze (you'll need either a vice or g-clamp too), though it can be done with some sockets and a lot of juggling.
Bushing tool - other makes are avilable :p

Nice one thanks.

I have a large work shop at work with vises and tool sets etc so should be able to drif them in an out.

Will order the bushes later and hopefully will still be alive at the weekend!

40mm, the gaps close up when you remove the shock,loosening the suspension pivot bolts will make it easier when refitting, but you may need to remove the chainset to get to the lower one.

Yep, that's why I suggested loosening the pivot bolts.
