2005 Jeep Wrangler X - getting a "rubbing or grinding" vibration at 45-50 MPH. see additional info below...

Stock suspension with 2 inch spacer lift and 32 inch tires, steering stabilizer. The rubbing or grinding vibrates the floorboard at 45-50 MPH (continues at higher speeds), and does it regardless of RPM or gear (tried 4th, 5th, 6th). I am stumped here..tires have clearance, shocks and coils appear ok...help???

    Does the noise change with the RPM, or just the speed?

    I'd agree with the previous answer of check the u-joints, and also say to make sure your drive shaft isn't about to come apart.

    Have you checked your transfer case fluid level?

    Have you checked all u joints? If a u joint is bad that would cause a decent amount of noise and vibration.
