    e150 metal to metal knock at full extension

    Hey All,

    I did my third 50 hour service yesterday. Pumped the fork and get a metal to metal knock noise at full extension. Checked are pressure (2) and made sure things were tight. Dis and reassemble and it is still there.

    Turning the red rebound knob up and the noise is less pronounced but still there.

    Also noticed the red rebound knob had only about 6 clicks, thought it had about 9?
    Blue compression knob seems fine. Black height adjust is okay too.

    I did a forum search but didn't find my exact problem. I'll keep looking...

    Any ideas?

    Thanks, George

    new problem

    Dis - reassemble one more time and I couldn't see anything wrong.

    I noticed with the air pressure at my normal 90 the fork was stiff so I started to lower the pressure, 80, 70, 60 all had knock-age and too harsh.

    50 pounds, hmm, fork feels good and no knock!
    Action is good and it feels like it should at 90 pounds

    BUT now I have a new problem. I always snug the pinch bolts on the lowers (sliders), just hand tight. This time I hear a new noise! (see attached photos)

    off to the bike shop I go...

    Hi George,

    I would recommend that you have your fork recieve a full service. Your fork's performance will benefit from fresh damping oil, o-rings, shims, oil bath etc. The lower tabs require only a very light torque 35inchlbs, if they are firmly torqued to 90 they will be comprimised.

    I have the same knocking problem and the stansions stay down about a quarter of an inch in the fork legs until I pull them back up.
    I brought my bike to a specialized dealer and they said they would get the fork warrantied.
    Three months later I get a call that my parts are in for the warranty
    So I get the bike back and I still have the same problems ,
    Do I go to another shop or call the same one again,
    Im starting not to trust any of them with this fork

    Thanks Speci-Tech. I really appreciate your help on this forum.

    Did you mean to say "torque to 90"? I would never torque the lower pinch bolts that high.
    I only hand tighten those bolts as if out on the trail changing a flat without a torque wrench.
    Really just hand snugged and never "gorilla-ed".

    I bought the bike in June 2007. Service record goes like this: 50 hour service, 250 hour full service with new 2008 internals (mechanic just got back from training at Morgan Hill) and then 2 more 50 hour services, so I think the fork has been maintained well.

    The original shock went bad and was replaced with a 2008 unit.

    I love the bike and wouldn't trade it for anything but 2010 Enduro!

    Anyway, the bike is now in the hands of Mikes Bikes in San Rafael.

    If you see "Mick" tell him I said hello

    Thanks again,
    George McNamara

    lowers not covered under warranty

    follow up...

    Just informed that the lowers are not being covered under warranty and new lowers will not be available until August

    New cartridges are covered under warranty.

    I'm tempted to ditch the e150 but don't think I can live without that stout front end.
    Sure like that fork when I'm slamming through the rough spots.

    Got an offer from an MTBR forum member to buy a used e150, might go that route.

    Happy Ending part 2

    LBS calls a few days ago to say my bike is done.

    Jaw hit the floor when I picked it up!

    Complete S-Works front end replaces my 2007 forks. No charge.

    Thanks again to Specialized and Justin at Mikes Bikes in San Rafael.
