Yes, the mechanism is definitely replaceable, and you can expect to pay appx. $ 100 for one plus shipping. Sounds like you have worn out the bushings. Its bolt-in, bolt-out but does take some time to do it, if you're handy its a good afternoon project, if you're not, then a local upholsterer should be able to do if for two hours of labor or so. H&M may sell this to you direct, if they won't then I can get it for you. Call Customer Service at 828-495-8235 and ask for Debbie, who does most the parts.
