Default Front N/S thump sound

Im getting a subtle but noticeable thump thump thump sound, sounds exactly like a flat tire from front NS.

Checked the tyres they were all in order. PSI all correct, lug nuts all tight.

Swapped front to back and made no difference.

So something in that nearside. Now would a wheel bearing not cause a whirr whiney sound and not a flat tire thumpy sound ?

All plastics are screwed on and everything looks normal under there..

As I hate people who don't update their threads....it was the wheel bearing.

many bearings make a whiny sound but wheel bearings are usually a low-toned grumbling sound

Bad wheel bearing can make all sorts of sounds...
