Re: CJ handling problems after 4" lift
Hi Tracy,
Nope, I wouldn't put my Jeep up on wobbly stilts, preferring to
radius my tub to fit 36" tires: http://www.----------.com/pismo.htm
http://www.----------.com/jeep68sand2.jpg To keep the center of gravity
low to be able to run side hill.

Yes. Just like you shimmed the rear - you shimmed the rear, right? If not,
this could explain your vibes.

The centerline of the crank, trans, tcase, and so on needs to be parallel to
the pinion. With the lift you have, there is no way in hell you will have
parallel lines with out shims. With the double cardan drive shaft in the
rear, then this rule is modified somewhat.
Your problem is gonna be on the front. You have so much lift from the
shackles that you have lost your caster angle, and the way to get it back
will make your driveline angles on the front even worse, and you could be
getting vibes from there already. To add insult to injury, one of the
corrective actions for the back is to drop the tcase some more, but this
will exaserbate the trouble in the front some more. The saving grace is that
the front drive shaft is so long that the angle differences will be less
significant than for the rear, so the solutions might be workable.

It would likely be better to put in the 1" taller engine mounts and
maybe help the angles better that way than a t-case drop.
