Tires round like new?
Tire/wheel balance?
Idler arm replaced?
Pitman arm slop?
Shocks good?
Try rotating front wheels to the rear & bring rear wheels to opposite front sides (helps prevent tire cupping)
Maybe a shop will give you a written guarantee of perfection & 100% satisfaction of their work OR you get a full refund $? Without time limits...

Others here have experience, hope they will post advice... Best of Luck
