I just bought my first Max IV and am loving driving it all over my 14 acres in VA. It does make some occasional weird clunking noises that sound related to the chains/sprockets/bearings. The transmission doesn't make any noise that I can tell. I've greased all the outboard zerk fittings and lubed the chains which are new. Being a machine from the late 90's I'd like to go through all the bearings and replace them. Partly for peace of mind, and partly because I don't know how rough of a life it's had. Does anyone sell a complete kit with all the bearings and flanges I would need to complete the job??
