Hey guys, not sure about this one. I installed a R.E 3.5 super flex lift a month ago. After the install I noticed some noise from the transfer case during decel so I installed a t-case drop, problem solved! I was running 75-80 mph with no noise or vibes. I just had my new wheels and tires mounted and when I reach about 53 mph and everything gets shaky. I took them back to the tire store to have them check the balance and 2 tires where a little off. I left the shop hoping all was good but again vibes at 55mph or so. My question is can this be something else? The u-joints seemed tight but I will need to shim the rear a little I noticed.
