Truck's sittin' a little crooked - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Cruisin' Oklahoma · 07-11-2010, 11:15 PM

So, I've noticed when my truck is sitting on flat that it seems to sit up a little high at the back of the cab. The gap between the bed and the cab is smaller at bottom than at top by a little bit...I'm going to post one pic now and will post another tomorrow to get a better pic. I just can't exactly figure out the best way to fix a problem like this...Not a big deal, just gets on my nerves. I think it could be a body mount issue on it, what do you guys think?

I never would have noticed if you hadn't mentioned it, but I can def see what your talking about. My guess would be the cab mounts, but idk maybe someone dropped a heavy load on the back of the bed.

If the cab mounts are fine, I would just add spacers (big flat washers) between the frame and bed at the back if it really bothers you that much

I don't think the bed is bent. I think maybe it needs a little shimming down @ the front/ up @ the back and while your there, check the cab mounts maybe po used the wrong size @ the back? anyway my stepper bed sits on the frame and has no shims at all. you will figure this one out just take your time and be as systematic as you can& look at the big picture cheers, Pat

Or the whole frame is bent. I tweaked my truck by running one tire up on an angled retaining wall to see how much the suspension would flex. The bed rubs on the back of the cab all the time now.

after 40years its not unusual for a work truck to have a bit of a tweak in it// i'd do as suggested and just shim the rear of the bed a bit
