Outer Limits 4x4 Board

Recently hit a bank hard at bout 80kmh out bush in nissan GU patrol. At impact it actually spun the steering wheel bout half way round on spline of box. On way home could not drive over 50 kmh without nearly running of road from death wobbles. I replaced panhard rod bushes, cheked wheel alignment and all good. Front tie rod seems not to be bent as well. ANYONE GOT ANY SUGGESTIONS ON WHAT ELSE COULD BE CAUSING THIS. IT IS ACTUALLY UNDRIVABLE AT MOMENT IT IS THAT BAD!!!!!!!

Have you checked the front wheels are not buckled or badly out of balance? Also have you checked out the swivel bearings and wheel bearings?

HAD 36 SIMEX ON WHEN HIT BANK. NOW GOT OTHER 35 TYRES ON OTHER RIMS SO NOT THAT. POSSIBLE SWIVEL BEARINGS. WHEEL BEARINGS ARE GOOD. WILL CHECK PRE-LOAD ON SWIVEL HUBS TODAY. CHEERS

damaged sector shaft in steering box, steering damper internally damaged,
