Hi, I have the limited slip diff on my Pathfinder I'm pretty sure as its a 94 with the alloys, 31's and the factory adjustable shocks (comfort & sport). I am coming up to 200,000 km's - 125K miles. Anyways I'm sure that my LSD isn't working or isn't working that well as I can spin pretty good with one tire. 1. How often should I change my fluid? 2. What fluids should I use ( I pretty sure you need a special additive for the LSD to work)? 3. If the previous owner didn't put the special additive in does that mean the clutches are toast? 4. How much is it approx to put in new clutches into the LSD? TIA

I know that this is an issue with Pathfinder power locks - I read about it in the faqs but there wasn't that much detail. Can some one point me to instructions on what to do to fix my locks? Here's what happens: They are fine in the summer. Come winter they will auto lock on me - when I shut one door all the locks will go down. I also have problems unlocking the door - I unlock it and when the lock gets to the top it powers down - I usually have to hold the lock up with the key while I open the door. I apologize as I realize this has probably been posted before I just can't find it. Thanks
