The hardened synthetic buckskin should certainly be replaced. There 
are step by step procedures in the PTJournal and on the web.
How's the jack pinning? Wippen and hammer flange pinning? Is the jack 
spring doing its job?
Last but not least, how's the key weigh-off? Newton has posted 
ideal/acceptable gram specs for uprights, which I don't remember off 
the top of my head.
A small key lead properly placed might be just what's needed, if the 
other specs are within normal tolerances.
