Chuck,
I bought my set from Hall and KONI accepted my Hall receipt - are you saying you don't have your Pantera East receipt?
If not, then as Julian said, KONI’s fees for the service are not unreasonable.

I'm pretty sure Marino is still active, but even if not, you are sending the shocks direct to Koni, not back to the point of purchase. Koni offer a rebuild service for a nominal amount even if you don't have the original receipt.

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Unfortunately I purchased my shocks from Pantera East (Marino Perna) and I believe his Pantera business is no longer active.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

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
