i have drive line vibes at about 60mph now with the i6 and a 3.25 suspension lift.. and 33's. I am swapping a sbc 350 this week what will that change or will it be the same solutions as the 4.0l
It will likely all depend on your new driveline angles. Once you get your new drivelines and u-joints in...you may have to make adjustments if you have vibes. I would imagine having adjustable control arms might be a good idea.
