The OEM LSD in my XRunner lasted less that 30,000 miles.
I believe the same diff is in my 05 Tundra with a URD Supercharger on it and that truck has 115,000 miles and I think the LSD is just starting to give up now.
How many licks does it take to get to the center of a Tootsie Pop? I think it varies greatly.....
Well is that due to the pressure placed against the clutch packs due to the spring and shim. In which case adding more pressure to them would get a little more life out of them. I don't mind purchasing a whole new carrier that holds the clutch pack assembly and installing a brand new one if any of these super wizards with a parts fische can actually figure out what the part number is to buy that actually had the LSD. I don't particularly want a whole 3rd member. I asked the parts dept at two different dealerships and you can't buy just the clutch packs. My local driveline shop couldn't get them either. So, replacing the center carrier in the diff that holds the LSD is my current standing. It's cheap. $350 from what all the parts fische show but which one is the right one. I hate to buy it and end up with an open diff like whats in a base model 2wd truck.
