The slow return to centre is caused by the factory stabilizer, other factors in the setup may be contributing but the stabilizer is the primary cause. I swapped out my stabilizer early on for an Ironman 4x4 unit (that is used primarily on landcruisers) and it returns to centre like any other vehicle I have ever driven, live axle or independent suspension. I daily drive in a heavily urban area, one hand on the wheel all the way wax-on wax-off style, many tight turns, over six sets of tram tracks and a 180 degree P turn with no issues. On the 180 degree turn I essentially let go of the wheel half way and slow down the return to centre using my thumb and index finger and it returns fully the whole way by itself with no assistance. No experience of death wobble, also have had wheel alignment done three times (twice at dealer during software update then first service and once when getting new tyres fitted). I will probably get a wheel alignment done every time it is serviced.
