I have an almost new Trek Liquid 10 with the Fox Talus rear shock. On every compression stroke of the rear end, there is a "marble in a coffee can" sound, apparently coming from the rear shock. It occurs just as the shock is starting to compress on any hit except an extremely slow hit. I can make it happen by either lifting the rear tire off the ground an inch or two, and dropping it, or by sitting in the seat and pushing down. It happens all the time and is beyond annoying. Trek has never heard of this problem, they say. Is this a problem with this shock or frame, or is this a normal noise. Thanks.

I recently got a Liquid 20 also and while I haven't had any problems myself, in reading the reviews on this site before I got it I might have come across the answer to your problem:

A lot of people mentioned hearing a noise they would swear was coming from the bottom bracket or the shock or something in that area and usually the fix was to take out the seatpost and lube inside there and that would solve the noise problem. Hope that helps, later, LR

Dumper - I'm have the exact same problem here with a brand new Ventana X-5 - a clunking noise coming from the rear shock area. I can make the noise happen doing the exact same things you are doing to your Liquid. From what I've been told, it's a bad upper shock bushing. See this post: http://forums.mtbr.com/showthread.php?t=86448 Let me know what you find out about your issue.

I had the smae issue with my Fuel. It was the main pivot bushing being worn.

You can check wear by grabbing the seat and top of the wheel in the other hand and push and pull opposing directions perpendicular to the direction the bike travels. If there is play you have worn bushings/bearings.

On the good side, a bushing change for me solved all issues.

You guys may be right, but on my bike...

it was actually the Talus shock itself! I swapped the Vanilla off my old Heckler onto the Liquid, and guess what, no noise. I called Fox and they, as usual, claimed they had never heard of this before, but that it might be "valve noise from the travel adjust mechanism." Whatever. I replaced it with a Manitou Swinger 3-way air- no more noise, and a much better riding bike (does not blow thru travel like the Fox).

dumper, I've been thinking of replacing my TALAS rear shock. Mine doesn't make the rattle sound but the upper chamber adjustability doesn't work. I'd like to get it rebuilt while still under warranty and then move it. What sort of deal, if any, did Fox make with you if it was under warranty?

Was considering the Swinger 3-way since the frame was designed to use it in some models. Sounds like you're stoked on it.

one other question ... which eye 2 eye and travel did you specify for the Swinger when you bought it? I've seen the TALAS off the Liquid listed at both 7.875 and 8 3/8.
