Sounds suspiciously like CV joint, particularly if it occurs under
power, with the wheels turned, pulling away from a kerb, or
going round corners.
Clunks, rather than a repetitive knocking noise, as you apply
or remove power, possible something loose in the suspension,
worn bushes or loose bolts.
I take you have had the hub cap off and it is not loose wheel
bolts, and that the main centre big hub nut is firm and staked
into its notch on the shaft.
Enthusiasts often do DIY jobs, the centre hub nut needs
a lot of torque, and a torque wrench with settings higher than
the DIY market torque wrenches.
