[DeTomaso] Techno question: Koni shock bump stops

[Frank Lisi]

Thanks Doug,

Unfortunately I purchased my shocks from Pantera East (Marino Perna) and I believe his Pantera business is no longer active.  

If anybody knows that this is not true please let me know.  Also if you can provide contact information that would be helpful.

Thanks

    Chuck and Frank,

    AFIK, KONI shocks are lifetime guaranteed for the original purchaser.  If you're fortunate enough to have kept your receipt, you can send the shock(s) to them and they'll not only replace the bump stop but also rebuild the shock to "like new".  I had that done to one of mine that had failed but it was 15, or so, years ago.

    Hi Chuck,

    What a coincidence, I just started attempting to resolve my Konis'  deteriorated crumbling bump stops.  I found the replacement part on Amazon, (of all places) sold by a third party seller called Performance Guarantee (I believe they only sell through Amazon I could not find their direct web site)

    The part number is Koni 71 34 42 000 0, two bump stops for $25.63. That said I am not sure this is the exact replacement part as my existing stops are deteriorated and any number indications are long gone.  Once I receive the parts I will let you know.  

    BTW the thought of needing to disassemble and reassemble all four shocks does not excite me.  I am willing to send them to a service to have the replacements installed, however I have not begun that search.   

    The Koni web site is https://www.koni-na.com/en-US/NorthAmerica/Products/Accessories/BumpRubbers/

    Let me know what you find.

    All the Best

    Frank Lisi

           Dear Forum,


                     During a long sporty drive this week there was a new
           squeaky/squealy noise from the right corner only during  left turns at
           more than 35 mph or so.  I thought that the high positive caster had
           resulted in the tire contacting the fender lip.  I had solved that
           problem over twenty years ago and I did not understand why it would
           return.


                      Inspection showed no obvious fender contact on the tire nor
           of tire contact on the fender.  I removed the wheels and did not see
           evidence for a leaky, failing Koni shock.


                      I did find that the bump stops, both right and left, look
           they are well into crumbling deterioration.  I think that the smaller
           effective bump stop permitted more suspension travel which did allow
           some tire-fender lip contact for brief periods.


                     It obviously happens, but I have not heard of failing bump
           stops.  I presume that this mundane failing part will require shock
           removal to replace the bump stop?    Has anyone else been down this
           proverbial road?


                                    Warmest regards, Chuck Engles
