New tires and a wrench

I ordered some new wheels for my 1/8 and a wrench so I could get the on easier (adjustable wrench doesn’t work that well). the new wheels looks really good with possible more grip then the old ones, but sadly when I got home and wanted to try them out I found out that there where something wrong with the car. I think both my diffs are missing some teeth. So need to open them up and take a look.
