84 CJ7 Rear Driveshaft
I have an 84 CJ7 with about a ~4 1/2" lift, dana 300 tcase, and AMC20 rear.
Currently i have the stock drive shaft and maybe about a 1/2" tcase drop.
Offroad i dont seem to have much trouble, but on road there is a pretty noticeable vibration. I didnt have time to fix it in the past, but now i do and would like to get it working better.
I want to swap to a double cardan shaft but had a few questions.
To change my rear axle input angle to point up towards the tcase output, shoudl i go with angle shims, or weld on new perches? I think im leaning towards welding on new perches.
On the tcase end with the doubel cardan shaft can i use the stock tcase output yoke? Looking at the tom woods website for CJ's it looks like they reccomend a flanged connection rather than the stock type yoke, why is this?
I understand i coudl use an XJ front shaft and tcase output. Anyone done this? The tcase output matches up with the Dana 300 tcase correctly i assume and i just ahve to shorten the shaft? When i shorten is do i make it so that the shaft is in the middle of its stroke at normal ride height?
When i rotate my rear axle to work with the double cardan shaft is it ok to run with the stock driveshaft until i get my new shaft installed?
Any help would be appreciated
