There appears to be a few posts on wheel shudder and I can't seem to find what I am experiencing with my Triton.
I have plus 1 wheel diameter increase and when the speedo hits 100km/hr, my steering wheel shakes like a sh!tting dog. I have had wheel balances and alignments for no great success.
I have a DiD auto and I wonder if anyone else has shuddering issues at highway speed.
