Last week I noticed oil slung around under my truck. The seal on the driver side output shaft of the front differential had started to leak. I replaced it with a new one. The maker part of this is the seal press made on the laser cutter versus the roughly $100 seal press from GM. It worked great, except I smashed the shit out of my thumb twice holding it. Next time I’ll add a handle.
The surface was beat up pretty bad but the cheap plywood did the trick. If you find yourself needing to press a bearing or seal in give this a shot!
