Then you wouldn't get any vibes from it ever. Unless you get going over 45 mph in 4wd, and on smooth enough road that you could tell the difference.

You should lock up your disco and try to drive down the highway. I bet your jeep jumps off the road. Or better yet, don't do that.

Is it hard to get the Cs on square to the end of the tube, so I don't get bad camber?

No, just use one of those magnetic welding squares, and measure measure measure!!

Now, if I were to do this all again, I would have gotten a Dodge input shaft, added a 1" spacer between the tranny and chevy bell housing, stuck with the Chevy output shaft and tail housing, gotten a 32 spline input gear for the TC, drilled the tail housing for the flipped Jeep TC bolt pattern, and possibly still gotten a clocking ring. This would have given me almost 3" more front driveshaft length, as well as a slightly lower front TC yoke. It might even have let me clock the TC down a couple more degrees. And it would have put the TC in the right spot in my tunnel and I wouldn't have had to use the hammer.

It probably would have cost about the same at the time, but would add up to almost a thousand dollars now. The better solution in the long term will be to get a crawl box, which will gain me the same 3-4".

But in the mean time, I have a spare Dana 30 that I can hopefully easily twist and drop in.

Order a set of adjustable uppers and set your caster angle to 6-8 degrees.

At your ride height, caster is far more important than pinion angle.

How much do you charge for a pair of adjustable upper short arms?
