The Koni's sometimes only last 70K to 100K mi before the seals begin degrading or leak. Most see 125K or more. If the Koni is old stock, it will fail more quickly because the seals slowly harden from age. STAY AWAY from ebay Koni's unless they are willing to tell you the date code stamped on the housings.canysmc said:Dinan Enthusiast:
What is the mileage "life expendency" of these shocks/struts? 20K miles? 30k miles? more or less?
And can Koni rebuild or revalve like Bilstein?
