I Hate My Lift! Can I Lose the Shackles?
I bought this 1990 YJ a few months ago. It was already lifted, converted to a 350sbc/TH350/NP231. I don't really know what springs were installed on it. The shackles look homemade, 7.5" Center of Bolt to Center of Bolt. I would like to lose these shackles and go back to a stock size, or just a 3/4" shackle lift. My worry is the change it is going to make in the rear drive line. No existing SYE has been installed. There is a TC drop of 1 1/2" and the engine is probably as high as it can go. I have already shaved down the air cleaner lid to keep it from rubbing the hood. The rear drive shaft angle looks pretty good right now. The rear axle has been shimmed. Please take a look at these pictures and let me know if I'm ok just putting in shorter shackles, without having to make a drive line change. I am already in turmoil about the drive shaft. It's going to need u-joints and I have no idea what size these are! I have a very mild vibration from the drive train, and I believe it is either the u-joint at the TC end of the shaft or the bit of side play in the TC output cone. I will be rebuilding the TC case very soon. Thank you for your help!
