DeWalt 12 inch miter saw cuts are off.

[ABBEY thomas]

Blade at rest( all the way up) and is set at 90 degrees and as i pull the blade down to the work piece. My angle starts to go off. As i touch the work piece, the blade is off . Reads 89.5 degrees. Replaced pivot pin and the housing that supports the pin, but still off.
Does anyone else have this problem?

[johnny means]

Is it off vertically or horizontally?

Ironically I just watched this video the other day. Link to the point that I think is pertinent.
