I have a new Triton GLX auto and am experiencing a shuddering through the car when travelling at a steady speed. The suspension has had an upgrade but it is still present. Any ideas on the cause?
When you say the suspension has been upgraded, did that, by any chance, involve raising the ride height? Problems centring around shuddering and vibrations, vague steering and the vehicle generally having a mind of its own are very common among owners who have paid good money to have the suspension hiked by anything from two to six inches.
Aside from the legal and insurance implications of this, raising these vehicles can throw the wheel-alignment settings (particularly the caster angle) out of whack and lead to the problems you’re experiencing. There are fixes including eccentric suspension bushes to return the angles back to normal, but it’s a specialist job.
Beyond that, a vibration at a particular speed can often be traced back to wheel balancing. The wheel and tyre combination on these vehicles is quite heavy, so making sure all the balance-weights are where they should be is critical.
