I leveled my u225 torsalistic suspension today. very easy with my harbor freight electric impact wrench. I just had to buy a 5 inch long deep well 7/8 socket on ebay ($24) had the shims removed in 30 minuted and raised ride height in back 1". she is riding level now. I attached pics of the items to help others. Just loosened bolts about an inch with hydraulic jacks...
