X3 on the loose suspension parts, I wheel hard and the DW always ends up finding me, but once I go thought everything I can always find the bad parts and once replaced it drives great!
PS, a steering stabilizer is not a cure for DW, it only masks it! I do not have a stabilizer, but after a hard day of wheeling I could not go any faster than 35 - 40 MPH without getting DW. we stopped and took off a stabilizer from a trailered rig and bolted it on and it solved the DW good enought for me to go over 60MPH. when I got home I found a bad ball joint and a failiing unit bearing!
