Weird clucking/knocking rear left

[Timmsy]

So not sure if this has been happening a while but Ibe recently had the rear seats out of the to move some stuff so can probably hear it more.

When turning right or going round a roundabout it seems to have a clunking knocking noise when it's loaded up.

Also seems to do it when braking lightly at low speed.
I'm going to hazard a guess at rear wheel bearing but any other input would be useful

Thanks
