Jounce Stop Bumper ?
LOL, like an elephant sitting on the trunk?
HEY I've almost had an elephant sitting on it..:D back when I had no money and was a LOT younger I had a 1985 1/2 ton dodge pickup. I took both roof's shingles off of my house (1st and second story due to leaks) and just old as dirt. since it would cost 50 bucks to drop off the stuff at the dump and I needed all my money for shingles I decided to load it up, I put in stakes on the bed side holes and added 1/2 ply wood to give me more height to really load it and snatch strapped it to keep from bowing out. Needless to say I overloaded the truck something fierce. It was on the bump stop about 1/3 way to full and when I got it all in the front wheels were almost off the ground I could lift it up about 4 inches. hmmmm what to do. I know I have some old broken concrete that can be loaded on the front bumper and winch area to bring the wheels back down. It worked! ummm sort of. if I took of easy enough (/6 4 on the floor) I could keep the nose down and steer it. if I was moving at anything over 15MPH I had to hit the brakes to get it to go back down and steer. let me tell ya that was the LONGEST and hardest 10 miles I have ever drove. I would never do that now. just thinking about it scares me to death. It was just stupid!
the truck's title said the weight was 3845 lbs and when I went across the scales the operator shook his head at the weight and had me get off again to check out his scales.
He re-calibrated it using a known weight on a trolley and had me come back on. the truck weight in at 12,892 LBS! so I was slightly overweight. I checked the truck over and it didn't look bent or anything but it never rode as rough as it used to, I might have sprung my springs a little. and it didn't break or bend the axles! but it dod take the rear tires almost down to the rims it looked like a 1 inch side wall and that was an E series tire! I kept that truck for years after than and still abused it(never that bad again) but the darn truck never broke on me. the cab's roof rusted away on me and I sold it to a 18 YO kid who put another cab on it and drove it for another 4 years, then I lost track of him and the truck.
I loved that truck. 23mpg and tough as nails and ugly as sin!
