My 2003 had a vibration at anything above 60mph. I removed the wheels inspected the suspension no issues visible. Has the wheels balanced slight improvement. Rebuilt the front prop shaft, slight improvement. Today I swapped the wheels/tires between the 2000 and 2003. Vibration is gone. Either the 03 wheels are bent or the tires are coming apart from the inside. My last Disco I swapped on Range Rover 20” with centric rings so I’m now wheel shopping.
