I didn’t have to look at the reverse bow on the rear springs of this Isuzu to know ti was way overloaded. This moist soil mix is not light, and he’s got quite a few yards of it there, about twice what a truck like that and that bed are rated for. That dump bed lift is going to have a workout. I once got stopped by the Weight Police (yes, there is such a thing) in a rental truck, with a similar low-side dump body, for carrying more gravel than I should have, pushing the GVWR on the truck above its obvious rating. I talked my way out of a ticket and into a warning, because I told him it was a rental truck, and there was nothing posted on it as to its maximum gross weight.
Of course, I’m not pointing fingers, since I do this with my old Ford truck all the time.
Here’s the springs on that Isuzu. The main springs are bowed up, and overloader springs are pretty well flattened out.
Here’s my version, a load of moist, fresh sod. That was heavier than I expected, and the fork lift driver could not push the pallet any further into the bed, the friction from the rusty bed being too great. Not ideal.
Here’s my poor little 1200 lb rated springs, utterly useless now, as the axle is sitting firmly on the rubber stops. Rubber was used for the original Mini’s springs, but these are a bit firmer. It makes for a pretty stiff ride. Never mind the way the poor truck feels at speed (no more than 45): on second thought, never mind indeed. It’s not really appropriate…let’s just say that the I keep my distance from anyone ahead of me, and hope my tires hold up. Actually, I replaced these obviously rotted ones shortly after this picture was taken. When I took this shot, it made me realize how bad they were.
