I've had an annoying squeak which transfered across to my new frame with the transplanted kit. I can't pin it down but I did switch out my Shimano MX-30 pedals for some Wellgos and the squeak went. I decided I prefered the Shimanos, replace them and the squeak returned; it could be coincidence but I suspect that one of the pedals is squeaking.

Someone on here suggested that 'squeaks' are generally dry threads. There's a large lock bolt (labeled 2 in Shimano's [url= http://techdocs.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/PD/EV-PD-MX30-1840C_v1_m56577569830608621.pdf ]tech. document[/url] for the MX-30s. Would it make sense to grease the threads (I was thinking copper grease as it's a static contact) or is something else more likely to be the cause? There doesn't appear to be any play or roughness in the bearings.

Me!

Pedal is nice and tight in crank yes? Makes sense to grease/tighten the collar, but the weight is borne by the barrel the bearings are in, so grease that as well.

The pedals are nice and tight it the cranks, yes; I made a point of checking that. I've never dismantled pedals before (and can be a bit of a numpty) but the exploded diagram does make it pretty clear where everything goes, so I might give it a go if things persit.

Wind the axle assembly out. try it both ways as one is a LH thread (I think...). Clean it as you go as you don't want any crap to fall in there. Half fill the body with grease and re-assemble it, spinning the axle as you wind the assembly back in. Wipe off all the gunk that has been extruded.

As in the axle into the crank arm (tightens towards the down tube - the opposite of bottom brackets) or do you mean that the lock bolts have opposite threads too?

I mean the collar that screws the axle assembly into the pedal with a 19 or 20mm spanner

Glad to help!... Sorry, got caught up in making dinner.
Chuck some grease in them once or twice a year and they'll last for ever.
