I appreciate the long bar thoughts. I dont think I have the extra ground clearance to run those under the truck....


I will likely work on smaller issues and save up a little money, or spread out my purchases

 

She's back up on jack stands, started ordering some parts already, and i'll be ordering more parts this week






I'm still fighting my "time out" no start conditions, was able to pull fault codes during one no start event. I've got a whole list of things I need to check and verify after thumbing through the diagram books again... Of course the fault code calls it "input b" but that isn't labelled anywhere in the diagram like that......

And I am honestly not sure if that is actually the problem or a symptom of a different problem

 

Noticed in your UPDATE 16 video your concern with "axle wrap"
It may be the angle of the video but your rear pinion angle sure looks HIGH...even not torqued up? I have not looked at a 2 wheel rear suspension but would assume it is LEAF OVER AXLE? moot i saw the pic..... did you swap the front leaf hangars to lower it. Typical rear pinion angles are set -1 ->-3 deg DOWN on leaf spring vehicles. With such a short rear drive shaft and your pinion looking like 10 UP....thats gotta be death on that rear joint not to mention terrible vibration. Unless you just WANT to go 4 link an average fix for most hot rods would be pinion wedges first then a set of cal-tracs to prevent spring wrap. I don't think you have enough real estate under there to add a pinion snubber (plus they limit suspension too = BAD FOR TRUCK)
btw cool job on the truck

 

Its actually set -2 compared to the engine/trans angles

the second shaft "goes up hill" to the pinion so it looks pretty goofy. The pinion is climbing 10ish degrees based off my estimates.


I'm also getting a small growl from the driveshaft during higher speed coasting, so I can't shim the axle any further down


Bottom line is my axle is rotating a ton up and down, I've got additional footage from shifting from R to D and back in my driveway and even just the torque off idle its moving ~5ish degrees

I don't think I have room under the truck to run traction bars. Can't sacrifice 2.5 to 3" of ground clearance when I am currently sitting at 4 to 5" of total ground clearance

 

exactly my reference. pinion angle should be set to -2 degree DOWN relative to the DRIVESHAFT....not engine/tranny yoke. With your shaft running UP hill to the diff you need a whole lot of wedge to get that pinion down. Pinion should "climb" into a straight line with driveshaft. That would be standard idea.

Given you have an "intermediate shaft" that would be considered the same as your transmission as it is 100% stationary.

I think you will find most 4 link system will sacrifice that clearance also as the diff mounts must extend downwards around 3-4 inches (depends on manufacturer) unless you do like a triangulated 4 link. Another option might be caltrac SPLIT springs where the front spring is quite SOLID relying on the rear spring to be more "flexible".

 

I can assure you my driveline and ujoint angles are setup correctly



I've ordered watts link, and started to eyeball how that might get fabricated....

 

Hey Pat, I was reading your post and remembered a set up that may help the axle wrap problem. It's usually for a ranger but
thought it may work in your scenario. It' just a thought...hell ya never know it may be the answer....LOL I was thinking with your fab
skills this might idea might help.

 

Yah I had thought about that in my head too, havent ever seen a picture of that actually in use

 

Some parts are starting to trickle in. I've got about half of the axle parts I ordered, ordered basically one of everything on the axle. Oh and my watts link is here too. That's gonna require some fabrication......

Still need to order the 4 link kit and coil overs

 

You driving this thing around yet?

 

I have about 400 miles on it. She's back up on stands and addressing axle and rear suspension now



A few of my Yukon parts under the truck, removed bedcover to start prepping for bed removal



Drained the axle to prep for axle parts

 

All my axle parts are here.

4 link kit is in route to my house

Time to get busy!

 

Tore the axle down last night.






4 link kit showed up today, and I still have a few more misc parts in route to my house.

I need to pick up some more metal for fabrication still

Gonna build the axle and start to mock up the 4 link this weekend. Stay tuned for more updates very soon

 

Didnt have much time to work tonight, just leveled the truck frame, disconnected the shackles, and moved the axle up to "ride height" so I can start mocking up the 4 link and then take measurements for the coilovers

 

Got all the rear end goodies laid out, gonna start building the differential tomorrow




Set the cover and Watts bracket on the axle, so I can start to visualize the fabrication needed for the watts link
