Fixed my creaking swingarm with new pivot bearings now there appears to be vertical play when you lift on the seat and it knocks on small hits. Any ideas, new bushings or mount kit etc ?

Certainly a new set of bushes from …….. used to be Mojo for Fox? (been a few yeas now since I had a Prophet)
You might getr away with just replacing the bottom one and save the other one for later.

Er could of course be that your seat is loose?

If it's not been doing it long you'll get away with just a new bush.

Shock bushings for sure. Just feel around the bushings for play when you lift the seat. It will hardly move but the smallest amount of play will cause the symptoms that you have.

definately not the seat, how easy are the bushes to change its a van r shock.

Very easy if you buy the tool (something like this: http://www.tftunedshox.com/Miscellaneous/Mount-Kits-and-Bushings/Eyelet-Bushings or this http://forums.mtbr.com/showthread.php?p=4262621#post4262621)

I found it a PITA trying to get keep sockets positioned in the exact spot to knock the old ones out, but it can be done (if you're more patient than I!)
