Steering Problems? My solution

I have a 1998 p38 4.6 hse and for four years I chased a solution to various steering problems from pulling to the nearside, violent shudder and shake at 50 mph, steering wheel vibration and vague and wandering steering. I changed various components trying to sort the problem and in a nutshell there is a solution but as has been said in many posts on here all parts of the steering have to be correct. I changed the shocks the air bags the wheel bearings track rod ends drag link steering damper swivel joints centred and adjusted the steering box and did the tracking result my rangie drives like a dream. I have 19 in sport wheels on -drives like a dream change them to hurricanes with nearly bald wranglers - drives like a dream so it seems if everything is set up correctly it doesnt matter which wheels and tyres. How long this steering heaven will last I dont know but will keep all updated. Hope this helps and if anyone needs any info please ask and thanks to everyone who helped me
