Total noob here trying to familiarize myself with my new 02’ 4Runner SR5 with the auto tranny. I understand the ECT and Center Diff lock feature, but what I can’t seem to find out is if either of the diffs are equipped with limited slips from the factory? I assume the front is open, but is the rear LSD equipped? Haven’t had it on the jack-stands yet otherwised I’d have my answer

All comments appreciated…

 

Anybody?

Another look at the owners manual and the rear diff calls for strait 80w90 gear oil with no LSD additive so that rules out disc-pack style of LSD. Still could be a sealed vicious coupling LSD common on the imports, but I’m beginning to think it’s just an open-diff with the TRAC control preventing wheelspin.

 

Factory LSD's are very rare in the US.

Don't know if the chart is good for up to 2002, but do a search for "diff codes" - there is a link to a site that will decipher the codes on the door jamb
