After the 'U' bolts have been removed they need pushing away from each other. Hence my design. 1. Jack up the car, and place on axle stands. 2. Take 2 wood blocks 1"x 1/4" x3" and insert it in the space between the rack and chassis both sides. 3. Take 2 wood blocks 3"x3"x1/2" with one rounded face on each side longer on one side than the other. __________ ___________ |__________\ /___________| 4. Insert the two square edges of the two large blocks onto the two small blocks, rounded face up. 5. Place your jack under the junction of the two pieces of wood. 6. Raise the jack as much as is needed to separate the rack from the chassis. You don't need much. Should form something like this: bush bush =[]===========[]= rack []-____ ____-[] _big block -small block ***** ___ ***** chassis ***** ^ ***** jack
