Just got back from Poughkeepsie Ny, so i get to attempt to locate the grinding noise that started in Moab. Thought it was in the from the front end, but the noise got worse as i got closer to home, and the hubs were not locked. I then suspected the rear pinion because it got louder on deceleration, but as i got close to home it sounded like it was coming from the middle of the truck... I REALY don't want to pull the Marlin apart!
The great thing about a Toyota is it got me back home instead of stranding me in Moab!!! Gotta love that !
