Freightliner Coronado Frame Rail Change....

[mwilson]

Car crossed the center line. This was a hard hit for sure.

Trying to get pictures of the front of the frame rail but having trouble. Bent bad enough that the oil pan will not come off of the engine.

On the rear those bends are just ahead of where the fifth wheel mounting angles are so the loaded trailer was pushing sideways at some point during the accident....

Tried to get better pictures.....

Frame rail right behind the steering box...

Why wouldn't you glider kit that truck then?

Why wouldn't you glider kit that truck then?

Couple things come to mind quickly..

(1) Cab is untouched, no damage.

(2) Appears to be a really low mileage and very new tractor

(3) There is a reduction in value once you kit a truck. Even if that Tractor is a 2016 and you kit it into a 2017 glider it’s value is diminished in the eyes of future buyers and the insurance company.

Sounds good I was just curious thinking it would be cheaper to swap components out to a kit.

Looks bad but not really. Pair of frame rails, new hood and some other trinkets and it will be back on the road.
It didn’t go on it’s side or anything, oil pan still full of oil, etc..

I've not really studied the framework of a lighter duty tractor. Looks built like a 80's GM car frame almost. Definetly not like a vocational/ heavy truck or a Mack.
Double frames were mentioned here or in the other thread. We have in a Sterling that's double frame. Photo.

That looks a HENDRICKSON Pri-Maxx air ride. Those did not do well up here...

Mike, I'd have to check on that. It's not our spec- unconventional for us. We do more interagency work nowadays.

Double frames have a nasty habit of dying an early and slow death from salt around here. With no way to clean between them, rust and scale expands until the fasteners break or the rails buckle.

Looks like that's already happening in the photos Wayne posted.

My bet is smoke wrench.

The rear suspension is Hendrickson, but I don't know model.

Our spreaders are double chassis, live in salty enviro year round. We've never had a failure related to rust jacking between the rails. Not saying it isn't an issue though. We keep em min 8 years.

I wish the assembly line at Dodge would have built my first gen spring mounts with huck fasteners instead of soft rivets......rivets are cheaper, I know!

WOW, I worked for Freightliner Truck Manufacturing for 14 years. This brings back some memories. We were putting out over 200 a day.

We torched ours off.

18-12 years is next to new in the private sector when it comes to a vocational chassis.
