Hi my Toyotanation friends 
My father's 1MZ-FE 1994 200.000 km (124.000 miles) has a steering wobble (in a way, too responsive and soft) ONLY at speeds higher than 120km/h (74.5 miles/h). It doesn't feel safe at all driving above that speed.
But at 110Km/h (68 MPH), it feels almost as normal. The car has no other braking, steering or suspension problem otherwise.
What is your opinion about what would be the most likely cause, so I can start shopping around for parts:
1) worn out ball joints (I think I can do this when the weather allows).
2) worn control arm bushing
3) worn steering rack bushing (I wonder if I can do-it-yourself this yet. I have much more confidence after I installed the front struts 4 times now).
4) loose steering rack (what bolts can I tighten or I have to let the garage do the repair + parts ? )
5) worn discs (can this be possible even if the brakes are not pressed).
Have you had similar problem and what can be done at home or at the garage ?
