Wobbly steering defender 90

[Cassillis]

Recently changed all the suspension on my 1996 defender and polybushed it whilst i was at it. Now the steering has developed a rather noticeable wobble at 40-45 it will cease when pushed through this speed. Is it because

               A) i have been a clumsy git and managed to knock all the balance weights off the wheels or
               B) is it more likely to be the steering damper :?:

It could be one of many things and only showing now because the suspension has been done.

Steering damper is one to look at but also check:

Track rod ball joints
Tyre balance
Tyre pressures
Wheel bearings
Swivel housing pre-load
Steering box backlash
