I've heard about doors drooping over time on the aluminum bodied trucks. Guessing big 'ol farm boys using the door to climb in!
front and rearsHoly crap Tom, both rears rotted?
Yes rotors. But they did pads and calipers as well.I think he meant rotors/
That's good to hear. That has been my biggest fear, LOLI was stuck in a bad hailstorm a couple of weeks ago. My F150 was pelted with quarter sized hail and when I got home, there were no dings whatsoever!
Oh, ya!Bet that was a nervous ride home.![]()
What is going to happen when these trucks crash and burn?Fiber beds too, in Denali and Toyota has it in the Tundra (new for 22) and Tacoma.
But the problem with the aluminum bodies was if the truck got hit. Get hit in the left rear, it would flex the compartment body and pop welds in the right front. We saw that especially with the ambulance bodies when they moved away from steel frames. Have a major impact and you had to pull the skin off all 4 sides to check for frame damage.Fire apparatus was notorious for rusting out in the 60's and 70's so one builder started using all aluminum bodies and aerial ladders in the mid 1970s. Basically it changed the entire industry so within a few years no one used steel bodies. So, at least in that industry, aluminum bodies have been used successfully for close to 50 years now.
The early versions did have a problem with corrosion popping up under the paint, but I believe that was mostly due to poor preparation before painting. Where I worked we had a fleet of over 100 vehicles and as best I can recall none of the rigs produced from the early 80's on exhibited the paint popping and the problem of body corrosion disappeared.
They were also quite a bit lighter which made the braking on the big stuff much better. We had on group of five pumpers that were delivered with steel bodies and you basically had one good stop in them before the brakes faded. We had them re-bodied with aluminum bodies after they rusted out and braking was not issue with those rigs from then on.
