? Noise after suspension lift

Hello, newbee here with a ?. I installed a 3 1/2 lift, all leafs, shocks, transfer drop, etc... All went well, but now when I drive I hear a kinda of rubbing, grinding, woosh woosh woosh sound. sorry only way to describe it. I think it's from the rear driveshaft. The leafs had wedges built in them. Do you think my angle is off?? thoughts?

Also I hear it only at above 15 mph and it is louder when I accelerate.

Thanks and Merry Christmas.

merry christmas, and welcome. sounds tough, start with the rear d shaft u joints. if the springs had shims built in, and you did tc drop the angle shouldn't be a prob, but maybe the slightly different angle made a stiff or slightly bad u joint show up better.

if it was low speeds i'd think a backing plate, or something was rubbing. good luck and let us know.

put up some pics of your jeep with the new lift.

nice jeep man. you're right on the border. most people can get away without the sye with your set up, between the drop t case, and the shims you should be fine. sye is a better way to go though.

32" tires coming soon????
