I just finished putting front and rear Wagoneer springs on my zuke. I took 1the smallest leaf out of all springs. Had to extend bumpers 4" to mount springs. The front is quite a bit stiffer than the longer rears.
The rear axle was moved back about 1". Still am working on driveshafts z-link and shocks.
Used 4" shackles front and rear. 33x12.5x15 tires. No body trimming. Looks like I'll have a whopping 26-28" articulation.
How much negative arch can I have before I start breaking springs?
How much of an angle can I have on my front Dif. before I have castor problems?
I am told to aim the rear Dif. twards the output shaft on the transfer case?
It appears that my rear driveshaft moves forward about 1" as the rear wheel closest to the third member goes from full droop to full compression.
The splines on the driveshaft are about three and a half to 4 inches in leingth.
How much of the spline do I want meshed?
Thanks for any and all input,
Dale
