Whenever I sit on my bike (2000 m900) I hear an increasingly loud creaking coming from the rear shock. It's annoying, and it happens every time I shift my weight while sitting on the bike. I can tell it's the shock or something near it because the creaking causes a tangible vibration I can feel with my finger by touching the shock when it happens.
I've tried lubing all the connections and joints, but nothing seems to help.
I'm guessing other people have seen this. What should I do?
The shock bushings could be dry as well as the heim joints on the suspension hoop. The squeak may also be from the swing arm bushings. Best way to tell where the noise is coming from is to have a buddy compress the suspension while you listen. A mechanic's stethoscope or a long screwdriver held against the suspect part can help. The only way to successfully lube the shock or swing arm bushings is to disassemble and reassemble. The heim joints have grease fittings, but good luck getting a gun to fit, they are not your usual Zerk fittings and probably won't work anyway.
Many times the shock linkage rocker will rub on the seat pan causing a squeak/creak.

They all work the same.
My favorites are the Dualco's cause you can use what ever grease you want...

No they dont.
Depends. my fittings are stuck, so no grease gets in.
Howie, that type of grease gun is commonly used to grease air tools. Any reputable place that sells air tools should sell that grease gun.
If you have something wrong with your fittings IE they're clogged or frozen, then that has nothing to do with the design and is ONLY due to faulty maintenance.
Maybe you should take your bike to a reputable mechanic, I'm sure they can fix it for you. Then those grease guns will work for you too. [thumbsup]
jeezus you people LOVE to argue too damn much
