The steering on my 87' JDM BJ70 is causing me some concern after being parked all winter. Yesterday turning a tight highway corner at 90 km/h I was moving the steering wheel but the vehicle was not turning? Afterwards the steering wheel position returned correctly to center. Normal steering afterwards. Last fall driving on an unserviced road (goat trail) the drivers side tire fell through the road into a 4 ft deep crevice, the shackle flipped and put some pressure on the arm from the steering box, the weight of the truck was on the driver's side leaf leaf spring. I'm not sure if this has anything to do with it or not? The steering box is adjusted all the way to remove steering play. Has anyone experienced this before? steering box?
