Angry Broke the frame of 1/2 ton Chevy

I thought the frame was flexing too much....had the bed removed & found the frame broken in 2 parts & holding by the Airbag brackets
Both sides cleanly broken as if I had sawed them to extend the truck to make a limo....
Those y2k 1/2 Ton Silverados have waffer thin frames...DO NOT OVERLOAD them...I hauled a 2000lbs slide in camper & I think it didn't help
I hope the frame shop will be able to reconnect the front & rear of my truck & reinforce it too!
Good thing I was not towing the Safari the chains would have been no help

I would have to think,that when you air up those shocks,that you are transfering enough shock load to a small area on the frame,via the upper mount,that your creating a pivot point of regidity in the frame. You may want to toss those shocks,and if need be,use air bags. Good luck with the repairs on the frame.

In fact I reworded my post , as I have Firestone Airbags over the bump stop. I however think they are what caused the frame to brake for the reasons you stated.
The strange thing is that they broke from bottom to top...as if you would hold the front & cab down and lift the rear untill it broke
just the opposite of what one would expect with overloading.

Broke the frame

Were these add-on airbags? If so, welded on or bolted?

Airbags don't increase the capacity of the frame, axles, or tires. All they do is hide the fact you need more truck.

from your earlier posts i recall you don't use a weight distributing hitch.

do you think you are going to reconsider your hitch setup?

Mark,
Bolted, & placed under the frame rail

Moe,
The hitchweight of a 71 Safari is not a hazard for this kind of truck, but a loaded heavy slide-in over bad roads is .
So no more heavy loads & no WD.
YOUR WDH hides the fact YOU need more truck for YOUR behemoth AS

Panhead John,
The "old glory" beautiful pic seems to indicate that YOUR WDH is not enough to keep your truck leveled , rear of the truck is low.

Hart

hey hart,

the trailer in old glory is not mine, it is rickstreams.

when we went to iowa to pick it up we used my hitch as rick had not purchased one yet (or the identical silverado as mine).

it was not perfectly setup. there was a small incline on that part of the street we parked on.

it towed home very nicely!

john

Huh? So engineer Hart believes that ALL WD hitches are a sign of a weak tow vehicle?

You have the proof setting right there in front of you, how can you argue against that?

LOL! Not hardly! I'm not the one with the broken frame, and doubtfully will ever be, since Ford uses the same frame (and brakes) on the F250 through F350 dually models.

A WD hitch mainly keeps your rear axle from having to carry, in addition to the tongue weight, all the weight that was leveraged off the front axle, by putting it back on the front axle. The important thing is that it maintains the weight on your front tires to give them grip when turning, especially on wet pavement.

Don't get all defensive... I didn't say you didn't have enough truck for the trailer. You obviously didn't have near enough for a 2,000 lb camper (that was the DRY weight, right?) and the airbags hid that.
