I have a 48 1.5 ton flat bed, all original with single speed rear axle and 4 speed gearbox, that vibrates/shakes/bucks when driving up towards around 30mph. Along with that there seems to be a bad bearings type sound that I only hear when driving in 4th gear. Any advice on where to start would be great. Thank you.
