I recently installed a 4.5 inch lift on a 2001 Cherokee with SYE and CV driveshaft. There was no vibration or humming sound when driving on stock tires after the lift at any speed, but when I put on 32 inch tires an intermittent humming sound appeared when I get up to 45-50 mph that sounds like it is coming from the front. I wouldn't think this would be caused by the driveline angle because there was no noise after the SYE was installed with stock tires. I noticed that one of the rims was bent on the front passenger side. Does anyone have any ideas what could be causing this sound?
