paralever creaking noise

When I push down on my seat (bike static) or under breaking a creaking noise comes from the wheel end of the paralever/ swing arm. I have pulled away the gaiter and given it a clean (some ingress of dirt). It stopped for 10 miles then the creaking started again. I have also undone the torque arm and then pushed down on the seat. No creaking. Tighten it up again, creaking.

Please has anyone got an idea what it might be.

Thanks
 
Bevel Box Pivot Bearings?

Hi,
Sounds like the taper needle bearings are dry/worn or more likely both. Someboby else had a similar query a couple of weeks ago?. It's fairly common.
These are the bearings mounted on the two pivot pins immediately in front of the gaitor you removed. However I'm not sure why the noise should disappear then return when torque arm is slackened then tightened?, but I do know the creak from the pivot bearings is usually worse when bevel box warm after a run - ie b/box expanded slightly due to heat but s/arm still cool, so pre-load is increased?
Reference torque arm -- please note this should only be tightened when the suspension is loaded to it's normal running height - ie off stand and heavy rider sitting on bike and tighten in this position. The movement in this joint is only provided by "twisting" the rubber in the Metalastic-type joint fitted here so this is important so ensure rubber is twisted slightly in both directions from normal ride-height rather than all in one direction from c/stand height.
If you wanting to change these bearings yourself I think I've got a "layman's" guide (ie no B-W special tools etc) which I got from the Motorad S.A. web site.

Strangely enough I've just noticed this same noise only yesterday!

Is there an easy fix?

What do you use to grease it?:confused:

always happens when ambient temperature rises on mine too. More or less above 15 Celsious. It has to do with metals expanding, don't believe it is something serious, or at least I hope so!
 
Oh yes!
You will find that the short part of the drive shaft (from the rear axle end) has seized into the main driveshaft with something that resembles black glue.Consequently the 2 sections of the driveshaft cannot expand and contract along the splines as the wheel travel alters hence the squeak.Its an absolute bastard off a job to get the 2 sections apart and then to scrape off the loctite or whatever it is between the splines.GOOD LUCK i've done a few.
Grease you need is something called OPTMOLOY paste which is used when there is a spline application,available through dealers.DO NOT USE COPPASLIP!!
 
Creaking paralever

Could anyone please advise where I can lay my hands on the tool for un screwing the rear paralever bush. Looks like a large allen key but it is not.

Thanks

It is an allen - not sure of size as bike at home but you will need the socket type, wrench and heat to loosen the locktite
 
I too have noticed a creaking from my rear end (:eek: oo err missus!) but had put it down to the bush at the bottom of the shock.

Will try and listen again once the wind dies down so I can hear myself think in the garage!
