Bubbley11 Posted November 1, 2013 Share Posted November 1, 2013 (edited) How can I and what is the difficulty? I really would like one but if its better, I can just throw a ratcheting locker back there. But that eats rubber right?

Hamz Posted November 1, 2013 Share Posted November 1, 2013 Just find a lsd diff head with same gear ratio. And swap them over Link to comment Share on other sites More sharing options...
silverton Posted November 1, 2013 Share Posted November 1, 2013 You're better off with a locker over the Pathfinder paperweight of an LSD. Link to comment Share on other sites More sharing options...
Kyle94 Posted November 1, 2013 Share Posted November 1, 2013 if you get a lock-rite or something of the same idea, it will only lock up when one tire begins to spin I.E. off road, or when cornering hard on the gas on pavement. other than that they're pretty tame from what i understand.

AndyC Posted November 1, 2013 Share Posted November 1, 2013 You'll know it's there around town, especially parking lots. How much rubber it eats is up to you. My KM2's have 30k on them and should last through next summer with proper rotation. Link to comment Share on other sites More sharing options...
Nefarious Posted November 1, 2013 Share Posted November 1, 2013 wd21 factory lsd is actually really capable. its somewhere around 270ft lbs breakaway torque. factory r50 lsd is pretty weak though at around 90 ft lbs breakaway. i just swapped over the whole rear axle from an SE model so I got the lsd and the rear disc brakes at the same time. easiest way to do it, really. if you can get a good deal on an axle anyways. mine only cost me 40$ for the whole assembly.

Bubbley11 Posted November 2, 2013 Author Share Posted November 2, 2013 I was just wondering if I run to the JY and grab on out of another path, that I could just swap it out for my open diff. It should be a drop in right? I could probably get the diff for 20-30 bucks at PaP, if im lucky. Link to comment Share on other sites More sharing options...

Towncivilian Posted November 2, 2013 Share Posted November 2, 2013 As far as I know, it would be a drop-in replacement. Make sure you get the same axle code (HG43 or HG46) though, I don't think you can upgrade to an HG46 if you have a HG43 axle - maybe on a 2WD Pathfinder, but then your speedometer would be off by a small amount I think.

Hamz Posted November 2, 2013 Share Posted November 2, 2013 hg46 will work if you have a hg43, just means your front diff will have 4.3:1 ratio and rear will be 4.6:1 ratio. will damage your transfercase if you 4 wheel on anything hard Link to comment Share on other sites More sharing options...
Nefarious Posted November 4, 2013 Share Posted November 4, 2013 Stick with the same gear ratio....u don't want that much difference between the front and rear... Link to comment Share on other sites More sharing options...
92Path_68CJ Posted November 4, 2013 Share Posted November 4, 2013 WD21 LSD is incredibly capable, don't let anyone tell you otherwise. It's all about tire placement and knowing your rig. Make sure it's for the correct gear ratio and you'll be good. Link to comment Share on other sites More sharing options...
Bubbley11 Posted November 4, 2013 Author Share Posted November 4, 2013 I am pretty sure I wont mess up the gear ratio, as I would always pull one out of a manual(hg43) like mine is. If all else comes to fail, I know how to swap the gears. Link to comment Share on other sites More sharing options...
Nefarious Posted November 4, 2013 Share Posted November 4, 2013 inside the door jam there is a sticker that lists the gear ratio. best way to tell Link to comment Share on other sites More sharing options...

fearkobe Posted November 10, 2013 Share Posted November 10, 2013 (edited) i have a question when i have my wheel turned when moving i hear off and on rumbling sound and you can hear the rear tire grabbing. is this normal been going this since i got it in 09? im assuming this is the lsd Edited November 10, 2013 by fearkobe Link to comment Share on other sites More sharing options...
92Path_68CJ Posted November 10, 2013 Share Posted November 10, 2013 On and off rumbling isn't normal IMO. Are you using LSD additive? LSD compatible oil is not the same. Link to comment Share on other sites More sharing options...
fearkobe Posted November 10, 2013 Share Posted November 10, 2013 yes i added it when i changed the fluid on the diff a few yrs ago. the old fluid was watery. Link to comment Share on other sites More sharing options...

fearkobe Posted November 10, 2013 Share Posted November 10, 2013 Hmmmm.... thats what i said. i need to check it again its been a few yrs. the on and off rumbling stopped after i changed the fluid but5 came back. Link to comment Share on other sites More sharing options...
Towncivilian Posted November 10, 2013 Share Posted November 10, 2013 (edited) What fluid & additive were used? How long was the prior fill in service? Is the fluid level correct in the diff right now? How many miles on the unit total? Edited November 10, 2013 by Towncivilian Link to comment Share on other sites More sharing options...
fearkobe Posted November 10, 2013 Share Posted November 10, 2013 i put lucas gear oil with the additive. i dont know on the miles im guessing around 180k miles it has 231k now. Link to comment Share on other sites More sharing options...
Towncivilian Posted November 10, 2013 Share Posted November 10, 2013 (edited) With ~51k on the fluid it's probably time to change. Lucas also isn't the greatest gear lube in the first place; it ranked the worst in Amsoil's independent gear lube tests; see page 19 of this whitepaper. Try finding some Mobil 1 75W-90 or Valvoline Synpower 75W-90; either one should have enough LS additive in them already. Change the front diff's fluid too and maybe the transfer case as well (usually it takes ATF but you can put 75W-90 in the transfer case, just don't mix the two; if you stick with ATF, use a synthetic fluid which claims to meet Dexron III specifications).
