Weird single knock noise..

[Hyundai]

When I changed to reverse, When I get going there is a single knock noise?

Then, sometimes, when I slow down a little harshly using engine braking I get the similar knock noise.

Sometimes when I set off into 1st after being in reverse, I get the same knock noise.. Any ideas?

im thinking a engine or gearbox mount may need replacing. check these for visual signs of wear and tear . or it could be a gear linkage bush that is worn.

Ive been having this problem since febuary. I sprayed WD40 all over and it got rid of the problem, for a month or so, then came back.

I've just checked the car, I see no worn out bushes or anything....

When i checked, it sounded like the noise was coming from the exhuast, but i cant confirm this yet.
