A Couple Of Mechanical Questions

With both front wheels off the ground is this play normal?





And secondly, is the notchy sound I can hear when spinning the wheel just the diff? It's louder the passenger side than it is drivers. Obviously you can also hear the brake rubbing at points too!

first one does look a bit slack try rocking the steering wheel rather than the wheel (help needed) and whilst the wheels off the ground put a big bar underneath and rock up/down

second one sounds to me like a bit of somethings catching the disc guard prob rust on the disc wheel off to check im afraid
 please excuse any grammer/punctuation mistakes,i'm thick,thankyou

Hi,
does look like a lot of play somewhere in the first one, think you need two sets of eyes/arms someone to rock the wheel as you are doing and someone to see where the movement is, but think you have some play in a ball joint or wheel bearing?
Try a bar under the wheel at 6 and hand at 12 and see if same play, sumets worn Shocked

as said ^ brake back plate in the second clip Question

No it’s not good, wheel bearing shot it!- unsafe to use until it is rectified.
 It can when others can't,
It will when others won't,
It goes where others don't.

Thanks for the help chaps.

I should have said both wheels were moving together when I was rocking them. So when I wobbled the one in the video the other side was moving too, and the same when I wobbled the drivers side. All of the play you see isn’t just in that one wheel! If that makes sense?!!

The sound I could hear which isn’t too obvious in the second video is either a bearing or the diff/prop. You can also hear the brakes rubbing somewhere but it’s the other noise I’m referring to!

If both wheels are moving whilst the clunk is going on, then you have an issues with the steering and not the wheel bearings, you will need someone to rock the wheel whilst you take a look see for the suspect.
I would hazard a guess at track rod end or inner track rod joints.

I jacked it up today and removed the track rod ends to see if the tie rods seemed loose. With the track rod end removed I pulled and pushed the tie rod but both felt ok.

I then got someone to turn the steering wheel side to side for me while I looked underneath. The noise sounded like it was coming from the rack itself. When I grabbed the drivers tie rod bar while the steering wheel was still being moved I could then feel play as it was being pushed and pulled against me. I could't feel that half as much on the passenger side though.

The vehicle pulls to the passenger side while driving and the steering wheel wobbles over 70mph. The front passenger tyre also looks like both shoulders are wearing out which is what led me to start investigating!

Should I consider changing the tie rods?

For testing purposes you need the whole lot connected to apply a load to the joints and using a torch to see whats going on get someone to rock the steering wheel a couple of inches either way, but as you can feel play with no load, I would say new inner tie rods and new track rod joints job done for the rest of the time you own the car.
