To check if its the wheel or swivel A(king) bearings.

Jack the front up - one side at a time.

Grab the tyre at 12 & 6 o'clock - push backwards & forwards - if there is any movement - most likely swivel bearings

Grab the tyre at 3 & 9 o'clock - push backwards & forwards - if there is any movement - most likely wheel bearings

Personally if either is loose - I would replace the lot - I just done mine - paid around $200 for a complete kit for both sides off evil bay (including a hub tool) - bursons wanted $400. Plus 3 tubs of grease.
