New to the CJ7 world and trying to end the "white knuckle" steering quality of my new-to-me '86. I know that it has been lifted 2.5" by spring and .5" from a 4" shackle. I want to replace the 4" shackles with stock 3" (greasable type?) to return the front castor and to level the rear pinion which is pointing slightly "up". Does this sound plausible? I've also looked into shimming as well. The jeep does have 33" tires. Been studying all the forums here with much satisfaction and have learned ALOT in a short time. Thanks to you All.
