I am currently in the automotive aftermarket parts industry and have had a job offer for a place that deals with HD & MD trucks...If anyone could fill me in a little bit about how things work on HD or MD trucks I'd appriciate it..ie brakes i would assume that suspension and mechanical parts would be similar to those of a passenger car light duty truck...correct me if i'm wrong

....well first and more improtant than anything else is computer skills and then the...vin number off the tractor....nothing can happen without those.... Other day when asked for my phone number-I gave the vin number of my Volvo......the mind is the second organ to go with the onset of old age....geofkaye

that's funny .....i wish more of my customers thought like you....i ask for a vin and they ask me without even batting an eye if i really need it to find thier part....i tell them straight up "if you want the right parts i need the vin, or i can send you the wrong parts and then charge you 20% re-stocking fee"
