My wishbone bushes were ok.
BUT
The following needed doing instead.
Front Wheel bearings
front shocker mounts
rear axle bushes
and for good measure i told garage to change the thermostat.
car did improve, however the knocking and jolt movement were still occurring.
So i dropped of to garage yesterday, i told him to double check front bushes, its turned out it was the anti-roll bar bushes.... not driven it yet as im still at work..
but my bro picked it up for me and text me saying "its a gud drive 4 its age"
sooo il take it for a spin tonight and feedback the final verdict...
