2018 Pete 567 Eaton 18speed manual.
Only 2way locking diff, interaxle and front axle. multiple drivers.
So 2 drivers complaint of hearing clunking sounds at rear of truck. It spins out easy when starting up empty or full. No traction control light comes one and it does not engage traction control.
I took truck for a with empty and full load, 63,000kg gross. It does spin out easy starting up, but I pulled some pretty big hills, crawling up a 30kph.
But something still doesn't feel right.
Anything I could check with this info.
