Tx...the wife says it sounds like rocks in the right front tire, but if it were so it would continue to make noise at higher speeds and it quits at 1 mph! By the way, whats your serial number if you don't mind sharing ( look at Muleskinner's posts on his
M7040 for wiring issues) and does it light the dash up to show the glow plug symbol before you turn the key on over to start? There is a big difference in wiring harnesses between the early to later serial numbers. My S/N is 50587, M9540DTH, eng 5Y0654.
