Hi I have a p38 2.5 DSE manual I am having a problem when I am driving the vehicle If I hit 50 mph the vehicle starts vibrating and swaying about on the road if I slow down it stops and if I speed up it stops. I dont have a clue what it is!!! Can anyone help. Cheers.
Check the tyre pressures and that the tyres are round????? then check all steering joints and have wheel balance and tracking done and check steering damper.
has it got p38 wheels or later l322 wheels? if it has the later are the spigot rings fitted,if it is still vibrating at 50 have them rebalanced again all 4 not just front 2.
