Long time reader, first time poster. My 97 F150 steering is all over the place. Have recently replaced ball joints upper/lower, front coils and shocks. When driving down the road there is a lot of play in wheel and it feels loose, ie: when you turn the wheel it doesn't immediately respond. There is no center return and it wanders from side to side. I have had an alignment done, but it doesn't help. Any ideas/advice would be great. Thanks in advance...
