Alright, my boss gave me his "old" truck. It's an 04 duramax 2500hd with allison. Big step up from my old 99 gasser with manual windows, non-functioning a/c/heat/wipers/taillights and the unopening pass. door and non-locking doors. Comfy seats too.
Anyway, had it for about 2 weeks now and I'm filling it up ALOT! I hand calculated the mileage the last time and I'm getting 10.something. This is about 50/50 highway street driving with a rather empty utility bed on the back holding maybe 100 pounds of misc fittings and 2 fiberglass ladders. It's 2wd as well. Oh it's got 43k on it.
Also, it's got a a funky rattle. When letting off the gas and driving at any speed (noticeable below 35) it has this loud rattle like sheetmetal rattling on something. I was thinking maybe something with the exhaust but who knows. If the window is down it sounds like it's coming from directly below the door. Is there a heat shield or anything that commonly rattles that can be tightened? It's pretty bad when people walking down the street lookover to see where the heallacious noise is coming from :mad:
