If you have any play at all, it's the bearings. And yes, as stated you will have to replace the whole thing. And yes they are pricing for 4WD vehicles.
And to answer you questions about the Timken being way more, I think they are just known as a very high quality bearing, so probably more expensive.
another way is to leave the truck on the ground, put your foot at the top of the tire, and push on the side of it really hard, if u feel a bangn your wheel bearings are going bard, also see how much play there is before the UCA starts to move
