Default SAS for my Chevy and more

By now I think everyone knows I killed the IFS front axle at Derrik's send-off

I literally broke it in half

So I'm putting a Dana 44 with all the goodies under it


The progress:

One of the piles of brackets from the old lift

Cleaned off the frame rails of useless bracketry. Also mocked up the new spring hangers only to realize I needed to pull the exhaust to move the cat back. The stock front cross-member will probably get cut out after the front spring hanger is welded in.

and plated it with 3/16ths

I also tapped the steering box, now to rebuild it. I hope to figure out spring placement this weekend. I'm pretty sure the brackets will get reworked some to fit the 52" springs and to keep the lift at about what i was before.

No Jack Stands!

Hopefully it settles in a bit more once the winch and bumper get back on.

Perches and rear hangers are just tacked in place. Got this for the shackle angle. I think it looks good, though I think the pinion needs to go up. The t-case output is just above and behind the x-member in the upper right. Not sure what this will do to the caster or highsteer.


And I need some welding advice. Is my Hobart 180 suitable for welding the spring perch to the cast pumpkin? I've read some say a nickel rod in a stick welder and some have just gone at it with a mig.

I found this page on Lincoln's site.

I'm going to try the no pre-heat method for the perch.

Back to the caster and pinion angle. Caster is about +4 degrees and the pinion is pointed up 6 degrees. The driveshaft would be at 20 degrees. Also the t-case is 4 degrees downhill. So, what are the thoughts on running it like this?

I say weld it up and give it a try on the road.

Here's a good article that covers Caster, Camber and toe.

when you say the t-case is "4 deg downhill" you mean it's pointing down 4deg to the front?? I would think that's unusual. I thought most set ups have the engine tilted down to the rear, which would make the rest of the drivetrain also tilted the same way.

Anyway, if the t-case is 4 deg down at the front and the front axle is 6 deg up at the rear then they are only about 2 deg off from being parallel. You might even be able to get away without a double cardan driveshaft.

Like Dion said weld it up and run it.
