This is a new very high quality and very correct spindle nut tool. This is the correct way to remove/install your spindle nuts. Don’t use a hammer and chisel. That ruins the nuts. This socket will fit the Front and rear spindles on the MB and GPW. It will also fit the front axle on the CJ2A, CJ3A, CJ3B, M38, M38A1, M170, and CJ5. This will work with a 1/2 inch ratchet driver or a long screw driver through the holes. This is a great item to have around if you have vintage jeeps. This fits a 2″ to 2 1/8 inch spindle nut.
