when i ordered my gears they said i NEEDED that pin so i went ahead and ordered it, started messing around with my newer rearaxle i bought just for the new gears and the crosspin did not fit. So i called 4 wheel parts where i purchased the gear set and i said the pin is WAY to big and i asked if there was another pin and they just sent me the wrong one, they said well thereis another pin in our system, maybe the one you have was labeled wrong, so i sent the one i had back, and they sent me the other one, same size, still didnt fit, Called them again and talked to them and they said that the pin i had was the only one they were showing in their system that i needed so i asked to talk to a tech and we finally figured it out that i either needed to get an explorer rear axle or find a new carrier that will work in my rangers axle to accept the pin i have. Ordered them from 4 wheel parts Parma, and if im not mistaken i believe i ordered them from a guy that worked there who was a member of one the ranger forums, i wanna say RRORC, not 100% tho.
