Is limited slip differential from 2002+ tundra actually an LSD?

Hello all,

this is my first post here because I couldn’t find any information on this topic on the web. I have a 2000 tundra that I’m looking to upgrade to a limited slip rear diff. The 2002 and up model years came with a limited slip option, but I’ve also read that this includes an ABS braking system that helps the slipping wheel gain more traction. Is this all there is to the LSD system, or is the pumpkin truly an LSD?

I ask because I recently came across a used diff from a 2002 tundra AC for parts that’s less than half the price of what I can find for used ones on eBay, etc., with less mileage too (~150k). They claim it’s the limited slip variant, but is this compatible with a 2000 model year without the wiring for the ABS limited slip stuff?

thanks so much and have a good one.

 

Yes, they used clutches. They’re most likely worn out by now

 

Not only that, but be aware the LSD on the 1st gen Tundras are finicky as shit with fluids. And that's probably a big part of the reason they're worn out: Owners don't know what chatter feels like, and either use wrong fluid, or allow wrong fluid to be used by shops.

If you happen to get an LSD, be aware axle housing width is different on the double cabs, and if you stick with Lucas 80w90, you should be golden.

 

I'm not sure how these all interrelate, but since I think that's part of your question, I'll make a statement, and the real experts can tell us whether I'm right or wrong.

The ABS has nothing to do with the LSD. The LSD is contained inside the pumpkin. The ABS is wired to the knuckles, and doesn't communicate with the LSD. So if it's just the used differential you're looking at, not an entire axle, you should be good. If it was the entire axle, you'd just need to plug the ABS hole somehow if your truck doesn't have those wires.

Eh?
