So I replaced my axle shaft on the passenger side of my 1980 3/4 ton. Now the hub wont lock. The only thing that should be incorrect is the cap is on backwards, so lock points at unlock and unlock points at lock. Would that cause it to not engage? The plastic of the cap looked like it was symmetrical and I figured as long as I knew it wasnt a big deal. Or would something else internally cause this? If I have to replace it... Im getting a new one. This is the original locker and I'd rather get a new one if I need to replace parts.
