I just bought my first TJ; 2001 Sahara with what looks like a 2.5 inch lift, new 32 inch Pathfinder AT's. I replaced the steering stabilizer with an OME and took it down to the garage for lube and alignment. Mechanic says the upper and lower ball joints are okay. The shocks look pretty good but I too have that vibration at 65 mph. Could it be the shocks? Rather than just start throwing money at it doing the remove and replace troubleshooting I would like to go at it methodically with the most common cause and work my way to the "I never thought it would be that" conclusion. Any thoughts, ideas or suggestions?
