    SL freehub sticking?

    Hi All
    This may have been done before and if so apologies.....

    I have the Dt swiss 420 sl rear hub on my 08 enduro sl, the problem i have is that the freewheel seems to stick intermitently. For instance, if i hit the power hard then freewheel the chain tends to such up - but not everytime, If i freewheel normally ( like without the jerky application of power to the cranks) this doesn't seem to happen. I have tried the lubing methods recommended by Zinn with no great improvment, so it looks like I'll have to resort to the lbs due to lack of tools. (this prospect does not inspire confidence)

    Has any one had this problem? did it need a replacment? ( i suspect thats what the lbs will say regardless) or was it a strip down and relube?

    One other thing what are your views on the "Load it up with degreaser" approach - Zinn reckons this is counter productive and ruins bearings - so i'm hesitiant to try it.....

    Any experiecnes will be helpful before i give up my wheel for a week to the lbs

    Cheers

    Most freehubs can be serviced: disassemble, clean and thoroughly degrease then regrease..... presto smooth action again.

    Degreasing the chain and cassette, then relubricating the chain will help smooth up the action as well.

    It does require special tools to remove the cassette and familiarty on how to service the freehub helps as well. Your LBS should be able to perform this service.

    Thanks Speci-tech,

    I'm generally pretty good at routine maintence and degrease and relube the chain / deraileur etc each ride,. I currently have the cassette removed and cleaned etc.

    Does the free hub strip down require any specialist tools? anyone donehtis on this hub??

    The only reason i am a little less than eager to go to the lbs is the previous history. eg two weeks after giving them my bike to change out a bottom bracket they "couldn't find" the right one - it took me 5 mins to order it online- it was delivered in to the lbs by myself the next afternoon and they still wanted €60 for the fix.....I have my own tool kit now and im not afraid to use it!

    Last word

    Big thanks!! this forum is a gold mine and getting solid advice from people who really know their stuff adds to teh fun of owning the SL.

    Which hub is it? You might want to go to the Shimano or DT Swiss web sites for more information and scematics of the hub. Those Shimano hubs are easy to take apart, but are truly a pain to get them back together with just enough tension on those cup and cone bearings to get them to spin freely with out binding or loosness. Besides suspension components, the only thing harder than rebuilding a Shimano LX, XT or Deore hub is building wheels.
