Rear DS opinions

This one? BEYOND PRECISE I wonder if the ford Chevy is the same on the back? Flip it? I'm leaning towards the NWF one atm.

Do your angles match? The extra mount on the 205 just helps with the gravity load of the t-case, and helps control rotation of the case due to torque loading. Neither one will have an effect on the rear driveline angles.

Agreed, first thing I'd check.

The angle of the output on the transfer case and the angle of the pinion yoke on the rear axle?

Yea I need it I think. I've been lucky to wheel it like it was built and not messed up the rear of the AW4 I think. I guess the side mount I put on from the start helped there.

Yes.You went from a CV style driveshaft to a non-CV style driveshaft. The two are designed to operate at different pinion angles. See below. Ignore the numerical values of the angles as yours will vary but note how they relate to one another.

That is what I thought they were referring to. I know mine is set up like the CV shaft.

You'll need to rotate your pinion down then. You can do so by shims (machined not cast please) or by welding on new perches.

Yea bout that.... remember when we were discussing track bars? Ugh.....
 
So this is what it looks like.




I'm thinking that NWF support is my best bet. That way they are on two supports. Should have done this when I built it but I always thought I'd wait until I 4 linked it.
 
Ok spent last week in Harlan from the 4th - 9th with NAXJA @ the Crawl. Thanks for building a beefy driveshaft. Now I have to deiced what to do about the fact that I have my pinion turned up for a DC shaft.... Thanks @Oliver's

If it is solely a trail rig and sees no road time, I wouldn't sweat it too much. By having the pinion up a little bit, it'll help keep the yoke out of the rocks. Obviously, we're not talking about a pinion that is turned up and absurd amount or anything.

Right now that is my attitude. It gets a little shaky when I let off after moving a little faster than I should with this thing but it's all holding together so far.
