The inside blade washer was warped causing the blade to vibrate. I put a new one in and now it runs good and smooth.

1. Typed in blade wobble for a DW706 miter saw in U-Tube and found a video that showed me everything to do. Everything in on U-Tube.
2. Replaced the two main bearings and the two needle baring assemblies.
3. Replaced the spindle gear, but probably didn't need to.
4. Put saw back together and still had blade wobble. Took off the blade and noticed the washer that fits inside the blade was worn pretty badly. Ordered a replacement, which cost about $3.50 and put the new washer on and all is well:)

Found several YouTube videos on potential issues regarding the wobble. The weakest link was the washer behind the blade that rides on the bearing. The next step would have been replacing arbiter bushings which would have been far more complex and costly. Replacing the $6 washer cured the issue!

Removed bolt that holds blade. Removed washer plate that holds blade. Removed washer that blade sits on. Removed (I guess it's called a bushing) inside what resembles the washer that holds the blade in place. It somehow became untrue. Put on bushing and runs like new.

Just replaced the bushing and it was all good to go. I replaced the other parts in the stack as well, just to be sure. Super easy.
