Important

Mac, my 95 XJ did the same thing when it was cold out. It has cleared up now that it is warmer; acts like a TPS honestly. Maybe swap out the TPS again or grab a Mopar one from the JY to try.
 
There's a TPS on the twin at the junk yard...maybe just grab that and the dizzy...

I will trade you an 01 Sebring for the zj. Once I get it running of course. Haha Need me a Jeep again.
 
They are either cut or formed (rolled), formed is stronger but if you are talking 35 spline axles it doesn't matter. Most stock axles are rolled.

I've seen splines made two ways... Cutting, and roll forming, I believe roll forming is far superior because you have all the metal you started with.

At least watch the rolling machine. They are awesome.

Rolling them is very similar to how we roll threads in our screw machines, just a little larger scale.

When axles are resplined are they machined (milled maybe?) or broached on??? Hobag knows I bet!

Like everyone said, they are cut, ground, or roll formed. Cut is the weakest, it forms sharp edges and cuts through the grain structure of the metal. Ground is better, it doesn't affect the hardening as much. Roll formed is best, it hardens/cold-works the metal a bit, doesn't cut the grain structure at all, and doesn't leave sharp inside corners that form stress risers.

Almost no one I am aware of rolls splines on axles except dana spicer and other oem shops. It is simply too expensive to do for small custom shops.

Inside splines are typically broached or EDMed.
