Dark94XE Posted July 14, 2007 Share Posted July 14, 2007 Exactly how tight should the factory LSD be? I had mine on jack stands, in park, and with a 2' breaker bar, I couldn't get the wheels to spin opposite directions. I mean, I was picking myself up off the ground, and no movement at all! I'm wondering if somebody welded the spiders. It doesn't bark around corners or in parking lots. Any insight? Link to comment Share on other sites More sharing options...
88pathoffroad Posted July 14, 2007 Share Posted July 14, 2007 If it was in park, doesn't that stop the driveshaft from spinning anyway? Link to comment Share on other sites More sharing options...

Dark94XE Posted July 15, 2007 Author Share Posted July 15, 2007 If the tranny is in neutral, you can spin both rear wheels in the same direction. In park, if you spin one wheel, the other is forced to spin in the opposite direction. My question is, how much resistance is normal in a stock Nissan LSD? I find it strange that I just can't get them to spin in opposite directions. I'm starting to wonder if the previous owner welded the spiders. I'm used to working on high horsepower vehicles (750hp Procharged Nova) that is using a clutch type LSD, and as you could imagine is pretty tight, but you can still force the wheels to spin opposite.

88pathoffroad Posted July 15, 2007 Share Posted July 15, 2007 The stock WD21 LSD has a breakaway force of around 280 lbs IIRC. I may be off, but the newer ones are REAL loose, like at 160 lbs? If it still drives fine around corners and doesn't make any wierd noises it should be OK. Link to comment Share on other sites More sharing options...
Dark94XE Posted July 15, 2007 Author Share Posted July 15, 2007 Thank you. That's the info I was looking for. The breakaway force is pretty high for a OEM LSD. Good to know. Link to comment Share on other sites More sharing options...
