50-60 wobble is thrust arms typically.
Have you had the car in the air and have a friend push/pull the tires to locate any play? I had play in the steering linkage from the box to the wheel that tightened it up quite nicely on my car.
I replaced my thrust arms a year ago but I have the 50-60 wobble especially when I hit the brakes so its time to do the thrusters again. I know what im doing now so it will be easier.
Part of maintenance I guess.
