‘82 GMC “Junkyard JIMMY” {Build bash Rebuild}

That's pretty close to what I was thinking but a little too much.
I'm gonna cut some metal and do a mock up...

It's still slow going at the shop.

I started making the hydro assist ram mount.

That's about it for now.

Still shopping for a welder.

It was inspired by your set up Kellyjohn. :waytogo:

But it will still have my own personal custom touch.
 
High steer hydro assist ram mount

Similar but not the same.


Taking a page from Deulings CAD designs...

I clamped a piece of angle to the old tube notcher and drilled a speed hole

In goes a small piece of tubing.

It will look something like this when done. I'm going to wait until the axle is mounted so I can set the final height and angle.

I "Might as well" Cycle the suspension over and over again and carefully documenting every inch along the way while I'm at it. :deal::pimp:

The goal here is to get the ram as close to parallel as possible to the drag link with the hose connections coming out of the top of the cylinder.


I'm pretty much learning from the best around here and making the best of what I got to work with.:waytogo:

Road noises

I tried to make a video to show the road noise that occurs when decelerating at highway speeds.
This is 10 bolts, Detroit locker,4.56 gears,NP208,700R4,35"tires @ 65mph.

I wonder if the backlash in the rear is off, or if the noise is in the T case because it thinks it's going 100mph?

The new axles are going to be 3.73 gears. Do you think the issue will go away with numerically lower gears?
 
Ok so @ 2k rpm current set up your doing 65. Old setup reads 97. With 4.56's and a .70 over drive your d-shaft is spinning at 2850 Rpms. According to Dana max safe operating rpm for a 1310 shaft that is 52" long is 2650.

3.73s will drop you down to a 2275 rpm at the output shaft

-response from Supermotard750.


I guess 4.56 gears weren't the best choice for running 35's if I plan to drive to the trail.


Shop equipment-

I decided to go with the Hobart 140 welder. I almost went with the Lincoln but the Hobart won in the end.

Northern tool has free shipping and no sales tax. http://m.northerntool.com/mt/www.northerntool.com/shop/tools/product_200471413_200471413

Hopefully I'll order it when I get home from work. Then I can get this thread moving again.
 
Thanks Mike, I have a ways to go before I can even stand in your shadow. It's guys like you that inspire me to learn more and keep at it.

Can you believe I've been hacking on this thing for 7 years and never pwned my own welder?
It's about time!
 
I'm anxious to see how this Hobart performs. I forsee good things in future posts. :laugh:

Don't forget that the CUCV pickups came with 4.56 geared axles and little bitty tires. I think they were 235/65X16.5 or something small like that. And I'm here to tell you, their top speed is only about 60 or 65 if you're lucky. And that's with the diesel revved all the way out to 2,000 rpm or whatever. They came with a TH400 three speed auto though. Your TH700R4 at least has an overdrive. My point is, that may be too low if you're looking to keep your RPM down. My wife's brother in law had a CUCV like what I'm talking about, and he went to 36" tires and he said the RPM was about right for highway driving after that. That's with no overdrive of course. 3.73 seems too high to me for 35s though. It would have a hard time starting out. I think 4.10 is what I have and it does good on the road. Off-road, I would like some lower gears personally.

Lol, it's pretty easy to stand in my shadow nowadays. (Hi, I'm Mike and I'm Tubby) :haha:

On the tools, it's tough dropping the coin on that stuff sometimes. You had the wedding, different jobs, go-pro for the dog and what not to handle. It all comes in time. :thumb:

Just pretty cool that you are able to do it now and start to burn some stuff in. :waytogo:
 
That's the same one I have Paul.


It will do some good welds once you get used to the settings :thumb:

My buddy Wick has the 140/210 model. We welded the boomerang on my diff cover in 140 mode. It laid some nice bead. That's what sold me on this particular model. That and the price.


Your dog has Go Pro? That's awesome! :haha:
Yes sir. It was a wedding gift. We have 2 actually. I mounted one on KERKER and was posting videos. :D
 
I wonder what kind of videos my dogs would shoot. Digging holes and lying in them, chewing on stuff, play fighting, napping, barking. Could be entertaining.

Look who just showed up at my front door! :D:woot::woot:


Now I have to clean the garage. :doah:


Anyone care to have a discussion about shock mounts?

-( on the rear axle)Why are they typically mounted opposite of one another?
You know, one in front of and the other behind the axle, and one leans forward and the other leans back?

Will inboarding the rear shocks change the way it handles?

How exciting.

I think the reason they designed the shocks to work at opposing angles was to combat wheel hop and axle wrap. To my way of thinking, that would be the best setup for going down the road at speed, and having them pointing towards the middle would allow for more wheel travel off road. I would think you would be able to mount a shock with more travel if it were pointing towards the middle.
