Jack it up and check for play push wheel up and down while a mate looks to see if say a wheel bearing is worn or need adjusting this can also show worn kingpin bearings also left to right will show up movement in tierod ends some wheel bearing movement if you can feel it clunking/moiving but can't see what is worn get a shop to check out the front end
