Looking forward to seeing it finished !
It still smells a bit. Had lots of air fresheners in the shop and doors open as much as possible for the first while. The smell soaks into the metal even, but almost all the offending metal is gone.
It is getting 'bodydropped' Its kind of hard to explain since it doesnt really have a consistent lower body line- but the front fenders, front bumper and steps (will fuel tanks immediately above) will lay right at at the same time as the frame.

The 4 link on my s10 had metal bushing in all of the joint when I got it from the previous owner. Only reason I replaced them with urethane was for the look...never had a problem with them in the first place, other than the original design of the 4 link was horrible, and didnt work with the rear axle at all...and I mean at all. Some kid threw together a back half in a weekend so he could drag and that was it. Keep up the good work man, this thing is going to be ridiculous when its finished...my hat is off to you brother

Awesome

This thread and the Northstar threads contain so much @!#$ win, it is unbeliveable
I love what you do to these vehicles
This truck is going to be titties

Ah, if only "cornering" were the only concern. That can be controlled easily enough...what's potentially troubling is the presumption that road surfaces wherever it goes will be smooth as glass and dead level. Potholes, aprons, you name it...this is why vehicles use flexible bushings, to allow the rear axle assembly sufficient latitude to twist relative to the chassis. Not to mention the utter lack of absorption afforded by solid bushings, which transfer 100% of the shock to the mounting bolts and brackets.
Bill, Why are more people, NOT, understanding this?
I totally understand and I agree. The first time there is any weight on the back and you hit a pot hole at speed something is either going to break or bend.
Hmm, you guys must live near some really big potholes. It gets 4" of travel per side on the rear axle weight alone- so there is no unnecasary stress yet then for sure. Of course this doesnt take into account that it would be shared between front and rear suspension and the (minute) frame flex that is inevitible. I'm curious who else here has played with bushings and suspension setups like this hands on, and who is going on theory alone.
As much as i may be a novice builder, I am very confident in my brothers work and designing to the point that i have no worries. He is exceptionally good at what he does.
I realize we've splintered off into a different discussion with this, and please understand that I mean no disrespect to you or your crew. However, the nature of this Net Forum is to encourage open dialogue, and as such, when you post here you may have to endure some good-natured point-making.
Additionally, as an automotive engineer with 30-plus years experience, you can be sure I am not working purely off "theory".
That being said, here's the potential problem:
In the center drawing, we see a depiction of uneven road surface, pothole, concrete block on the road...you name it. In this instance, the rear axle is at a considerable angle to the chassis. As you've mentioned, it could conceivably be pushed up 4" higher on one side than the other. Under these angled conditions, a lack of flexible bushings will transfer that twist directly into your control arms. There is ZERO angularity allowable with your solid setup. Put another way, any angularity that would occur (and it will!) can only come from literally twisting the control arms along their length. Not only can this undesirable flexing cause fatigue and break the arms over time, the forces placed on the bolts and brackets will be significantly more than if flexible (or pivoting, such as spherical rod end) bushings were used. Additionally, the suspension movement will bind as a result of these terrific forces...smooth movement will be impeded at anything other than dead flat level, and this can lead to unusual handling issues.
Even pure drag racing cars, which may live in the most flat, hospitable environment possible, use spherical rod ends to allow this necessary independent movement and eliminate suspension binding.
So, I offer this information up not to prove myself "right", but to hopefully help you and others see that this may not be the best way to go, especially on a truck that is going to see the additional loads of trailer hauling. With a trailer on, a suspension failure, fully loaded at 60 MPH as you careen across a pothole you could not avoid, could prove to be catastrophic. Some of the worst "hits" I've taken in my decades of Interstate highway trailering are at the transitions onto bridge decks...these uneven surfaces can put a tremendous "bang" into the rear suspension with the additional weight of a trailer. I've cringed to think of the forces involved.
You good folks may have been getting away with it on other vehicles, but that's not a reversal of the above engineering information. I'd at least put some real rod ends on it for peace of mind.
Here's an example of a well-engineered system. Note the use of rod ends, both bushing-type and spherical-type:
And with that, I'll cease pirating your thread. Good luck with a cool truck!

Chopping the roof and laying the windshield back is not in the plans- it would just take away from the awkward size and shape i so much love about this truck
The above pictured car (for suspension) is real close to what i would love to build some day- old school, lightweight car with excessive cummins power

Rad, intercooler and trans cooler installed- dont want to take any chance on any overheating issues. Firewall removed and smooth one welded in. Brake booster set up.
Starting the floor, the rst of the floor and firewall are removed too- just not shown in these pics.

tight as hell! what do you have in mind for the paint scheme? cant wait to see more!!
nothing surpises me with you guys I am just speechless everytime you come up with an idea, couple of things though, will it get a HUGE chrome grill? how will this be to get alligned? and will you be suiciding the doors cause I think that would look tits!!
I must say...it is a very cool project. Thanks for sharing it!

Very cool bro.
You guys do amazing work.

There is a big polished grill for it ( the size of the opening in the front) Doors are being suicided- thats going to be interesting in parking lots with the big mirors too
Alignment will be the samme way as our other projects- i will do it on a holiday and spend as much time as needed since they dont tend to be 2 straight forward.
As for paint scheme- old school and simple.

Damn sexy heart she has there.
i just love how big and awkward the truck looks.. and its even better on the ground
is that snow on the ground off in the distance AND clothes drying on the line?!! CLASSIC!
this is one of the best build threads on JBO!
thats 1 sick truck man. keep it up . do some wild color with some heavy metal flake

I hope nothing ever goes wrong with the 5th wheel Or king pin on the trailer or else you will be headless
man thats sick. i think a flat bed would have looked better, with an optional 5th wheel.
i know its a toy but you get the idea.
