While doing my front wheel bearing after I have taken it apart I notice that the new bearing what for the car sit on a lip on the knuckle with the bearing in between.

There is a retaining clip that holds the bearing in the knuckle. It is the lip you see. The ring gets removed, then you can remove the bearing.

I've seen the clip but it's looks like a bit of the knuckle there seems to be a lip before the bearing where the drive shaft sits on it but the size of the bearing on many web sites that's for the car

Normally the bearing will be in the middle. There will be either one or two clips that secure the bearing in the knuckle, then a seal on the rear that runs on the outside of the outer CV joint and a seal on the front side that rides on the hub.

If you only have one clip, it is removed and the bearing gets pressed out that direction. I cannot find anything that actually shows that assembly, even the OEM book doesn't show the bearing replacement or I would post the diagram for it.

You have to press the drive hub out of the bearing, remove the seal and retainer clip and press the bearing out of the hub, the bearing sits on a shoulder and exits past the removed retainer clip, there are special tools required to do this, with out them you can damage the bearing

Does the bearing fit underneath when drive hub is out as the bearing I've been sold sits on the lip at the top so has the knuckle got a stop lip on it and I've got the the bearing press

The hub (inner red dots) has to be pressed out of the bearing (yellow dashes) first. Don't be surprised if the outer bearing race stays stuck to the hub and a bunch of the ball bearings fall out. If it doesn't come out (99% of the time it does) remove the outer seal that was under the hub.
Clean up the bearing bore and remove the circlip from the bore. Apply some lubricant.
Now set the hub in the press just like in the picture, the bearing will press out and leave a large lip on the back side of the green dashed area. The recess on the green dashed area is where the seal for the axle side goes. It is also the stop when you press in the new bearing from the other side. Re-install the clip (should use a new one but I have just cleaned the old ones as well.
Install the outer hub seal and set up the hub so you can press in the hub.

Make 100% sure you support the bearing race (yellow dashes) on the inside while doing this or you will destroy the bearing.

Once you have the hub pressed in and you install the inner seal at the axle side you can re-install the knuckle and axle shaft.

Now install the axle nut and torque it to the specified torque. DO NOT SET THE VEHICLE DOWN UNTIL THIS IS DONE! If you put weight on the bearing before the axle nut is torqued down you will not set the bearing preload in the hub and it will destroy the bearing in a very few miles.
