This is the DIY for Front suspension overhaul. So just pay attention to steps that get you to bearing, if you get to Step#10, then once the steering knuckle is dropped down a bit from the Strut Tube, then the 4 bolts holding the wheel bearing are right there. They require a lot of force to remove, so get a 2-foot section of iron pipe (the one used for natural gas piping at hardware store) or impact gun:

Here is another good DIY:

PS: If you have not done any Front suspension work, time to do a front suspension overhaul and change the bearings at the same time.

At 150K miles, your bearing remaining life is limited, so it is not a bad idea to change them now, it is a common failure even at 90K. Then after changing the bearings, if the noise still persists then address the tire issues. Or you can reverse the order: address the tire issues first, either approach is fine: your choice.
