Changing out a Wheel bearing! (How to)

Ok, I am putting this thread together cause I've looked everywhere on how to change out a wheel bearing. So I decided to put one together and after hours and days of learning how to do so and running into problems. I am finally done with the finish product. (I used my 1995 Tacoma to change out the bearings, but I am sure that this could be a guidance for the 2nd Gen's.)
So after taking off the tire I started on the brakes.
I tied up the breakpads to keep stress off the line and keep it out of the way
I have Manual locking hubs, make sure its in the free position. If you don't have manual locking just make sure you're out of 4wheel drive, and there will be a cap after you take off the cover.
Next comes this, The Red arrows are where you may have to bang the hell out of those screws with a brass hammer or a brass pin. This was the second hardest thing to do. once you bang it loose the cone shape washers will pop out.(The next pic I will show)
The Yellow arrow is where you need to unscrew the bolt out before you can take it down further.
Now the next part after taking off the silver star piece (I am horrible with technical names)
you'll come to exposing the axle spindle
This was the hardest for me. That retaining pin was a bitch.
If you haven't taken of the disc brakes yet then go ahead and do so.
Now the next step is to take of the whole knuckle. You'll need to unscrew 4 screws on the bottom where it connects to the lower control arms. Then disconnect the upper control arm.
Now you'll have the Whole knuckle out
After much searching for a special socket, I found one From MatCo Tools. This socket fits in these holes
Also The Yellow Outline is where a seal was, You'll have to get one of those for the front and back of the wheel bearings.
I put the knuckle in my wheel to brace it better when unscrewed it.
Now the final step is to Press out the old bearings and put in the new ones.
I had to go to a machine shop and get it pressed out and the new ones pressed in.
Then just backtrack everything and put it back together. Hope this helps out
Note: use a torque wrench to tighten in the wheel bearing socket nut at 203 ft lbs.
I re-packed the grease in the bearings, Only was able to get one side of the bearings off to re-grease it.
Be easy on the bolts and screws, I sheared off one.
