Hi,

When I go over 60 mph and then take my foot off the accelerator, the car makes a loud knocking noise. Also when I go left round a bend the car makes the same loud knocking noise.

Any ideas of what it could be?

Thanks

Engine or gearbox mount?

Can be your air intake tube nocking off the metal it seams stupid but my problem had something similar and it was just the air intake tube the bit were it sits on the car
