if you feel it threw your seat it's from the rear, through the steering then the front somewhere.

[jack460]

definetly from the rear and most predominant at 86 kays

loose flex plate maybe?

[sam_rigger]

are they the original rims/tyres?

Try different rims/tyres.

I had a shake in my FG ute, turned out the tyres were all out of round, for sitting in the sale yard too long. I was stunned that it solved my problem, I was sure it was something more complicated.

Iam with the above poster, I guarantee its wheel related. Try a different set and if it fixes it put your original ones back on one by one until you find the problem. Once you go above 90 does it seem to get better.

Try front to back first!

[jack460]

yes above 90 its fine and the tyres are not original
