First off if there is no such thing as a "positive locker" someone should let Calmini know because they are selling a "The LockRight positive locking differential is second to none." Second off, time and time again I will read a fellow Pathfinder owners question and will repeatedly see the reply of "SEARCH" over and over again. I don't care how many times I get asked the same question, I wont forward someone to a response from a similiar question asked who knows how long ago. I have been a Pathfinder owner for 10 years and would be happy to take the time to write a few words down to a fellow owner in hopes of making their experience a little less frustrating. I'm just looking for some input from someone who has had some experience with a posi rear end and if anyone has the time to write a few words on the subject it would be greatly appreciated. The funny thing is my reply to all this "SEARCHING" has given a greater response than the question??? I really don't understand? I have done 4 timing belts, 2 starters, replaced an engine, pulled injectors, repacked bearings, brakes, hubs, electrical issues, resoldered fuel pump terminals, replaced gas tank, radiator, hard wired starter, body lift, suspension lift, wheel alignment, exhaust, stereo and on and on. If anyone has any questions or needs some help I am more than happy to help you. I will not reply "SEARCH", I will reply "here's something that helped me"... So next time someone askes for some infortmation, if you have nothing to add... don't.
