I have a 87 Landcruiser Traytop 6cyl Manual and have what sounds like exactly the same problem. Started as an occaisionally vibration if I hit bumps on the road. Had shock absorbers, wheel bearings and hub bearings checked and OK. Drives fine offroad which is where it spends most of its time.
This morning I hit corrigagtions on tarmac with only the right hand side at about 60mph. This setoff a vibration which became much worse under braking to the point where I thought the front wheel was going to fall off (<- past experience).
I have the vehicle booked in for an inspection and will try to post what the result is back here when I find out.
And just to add, I have had this Toyota nearly 20 yrs. It spends most of its life working off-road and except for burning out the clutch once it has never caused me a problem.
