Review on Spicer 50491 Axle Shaft Seal by Joe Murphy

perfect fit! However, you absolutely need the tool used to tighten this guy. Anyone can do it using this part. I crashed my first one and had to order a second replacement because I didn't buy a tool. Please buy a tool and save yourself the headache.
