I have a 94 Runner. I have installed a huge subwoofer box in the rear of the vehicle. Now my truck has a squat! These trucks always have a slight squat to them in the rear anyway. Is there anything I can do about this on a reasonable budget??? Leveling springs, air shocks, load springs, ect........ Keep in mind, I have all the wrenches and screwdrivers in the world but do not have a welder, so bolt in applications are prefered! Thanks
