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.

No, down hill as in front of truck to back, since the pinion and driveshaft are both pointed uphill using the same reference. I welded it up this weekend so I'll see how it works.

An update for you guys. The front is mostly together. I need to plumb the arb, order and install shocks and driveshaft. Pulled the rear axle and springs out. Shackle flip got installed. Need to put arb in the rear and swap brakes and axles to 8-lug.

I have a shock question. Would 14" travel shocks in the front be overkill? I believe its set up for ~8-9" of droop. Also should shocks be mounted vertically or top angled towards the shackle end of the spring? For the rear should I keep the stock mounting (one shock on front and back of axle angled toward rear or front, repectively) or inboard them?

Front shocks- Depends on the flex you can get out of the front axle. You don't want to use your shocks as a limit strap.

Rear shocks- Front/Back doesn't matter, just get them above the bottom of the axles.

Angle- Doesn't matter in our type of wheeling. Just get them in where they will fit.

Small set back today. Axle shafts from the donor axle are half inch short so I can't get the c-clips on. Started to regear the donor axle and noticed that the pinion bearing races have some pitting from rust, as does the ring gear. Apparently I had been running with some water in the diff which I noticed when draining. Is this a problem and I need to replace them?

If they are Pitted you need to replace them.
Should be standard sizes that you can pick up Bearings and races at Napa.
Good Luck.

The ring gear also has some pitting and had a few heavily rusted spots that i cleaned up. Do you think its still OK to run?
