    I am buying a LockRite tomorrow and am going to be replacing my Auburn LSD in the rear. As far as what is needed? I'm buying a new pin but do I need new thrust washers for the sides? I have an idea how it goes in but I haven't read the instructions. Do I need a feeler guage for tolerances? A friend is going to bring his dial when I install it to make the sure the depth and back lash are correct.
    I'm going to help Blublaz57 install his too, does the carrier need to come out or can it stay in the housing? Any info you guys can give me is greatly appreciated. Toss this dumb dog a bone!!!

    You need an open carier, so you need to take out your Auburn and replace it will the factory one, or a new open carier. I didnt use an feeler gauges, but I put mine in a carier that had less than 500 miles on it (the front one).

    I got an open carrier from JEKBROWN today in the mail. My friend told me I wasnt able to swap the Auburn into the front and the front open carrier into the back. Turns out you can, but he was under the impression I had a dana 44 in the front. Oh well, now I have an extra open carrier when I decide to lock the front.

    once you get the new open carrier installed, it should take about 20 minutes to install. just slide the left axle out a little, and install the gears, using the old thrust washers (just follow the diagrams, really well explained), then bump the left axle back in, and install the c-clip. then do the same for the right side, except the right you have to install teh c -clip into the gear set before finishing the assembly (it will be cleared when you read the instructions). also you will need a 6" long piece of coat hanger wire to use as a "tool" for holding a part in the right place during assembly (this to is in the instructions). it takes longer to read teh instruction, and pump the gear oil in than it did to install the lockrite. JUST FOLLOW THE INSTRUCTION WORD FOR WORD, and everything will go real smoooth.
    good luck, and you wont belive the difference in traction. also remmeber to ease into a sharp corner whenever possible, to allow the gears to open up, and slip.

    You will need an open diff to start with. You have to use the thrust washers that are used with the factory side gears. If you have the correct thrust washers that are in good condition, you don't need to buy new ones. You don't need a feeler guage for tolerances. The manual explains how to check for correct installation. When I installed mine, I left the carrier in the housing, but I removed one bearing cap so it was easier to drive out the roll pin that held in the cross pin. If you have a thin ring gear, the Lock Right can be installed without removing the diff, but if you have a thick ring gear, the diff has to be removed along with the ring gear to facilitate removal of the cross pin. Hope this helps.

    Are there two washers? I only got one in the package. I'm buying a new pin so I'll just grab new washers I guess. How difficult is it to install the pins and springs? And do you run "posilube" with yours?

    Every little bit helps! The hardest thing will be my lack of patience. I'm chomping at the bit but I cant do a damned thing til I get to the savings tomorrow! So I'm sitting, staring at an empty open carrier and laffing to myself!!!!

    there are 2 washers, one on each side, and mine were real thin, so is it is possible that you have 2 and they are just stuck together. the pins and springs are real easy, if you just use a small scrwe driver, and you use grease to hold them together like the instructions say, and yes i use posilube, and i also use heavier weight oil, since it never really gets cold around here, i figured the heavy oil would help it run a little quieter. once you read teh instructions, you wont belive teh amount of time you spent asking all these questions. they really are excellent step by step with pictures. [​IMG] i was a little apprehensive about trying this myself, and now since i did it i cant believe i even considered paying to have it done. it really is just that easy. [​IMG] "JUST FOLLOW THE INSTRUCTIONS". they tell you everything you need. i had never even changed teh oil in a rearend before doing this. i also heard that was teh last place an inexperienced person should mess with. since then i have ordered new yukon axles and bearings, and they came in the mail today, and will get installed tomorrow. so this means i have to remove and reinstall my lockrite

    Waitin for usps to deliver my new full on detroit to Toybox becuase i've been thru not 1 but 2 lockrites in my 12 bolt. They will not stand up to 35 inch tires and 4.10's....lol. Make sure you use the new hardend pin...2 new side gear washers....i believe they mic at .030....and take that final measurement and make sure you are at or under the .170 spec! Use normal 80/90...no LS addative needed.

    Sinan, send me your # on a pm. Im more concerned about installing the open carrier. My friend pretty much guaranteed me that as long as I keep the shims in order and put them back where they came from I shouldn't need to check the depth and lash. Ill throw a dab of paint on the gears and see how much washes out before I call him over!
