Ah I didnt expect that, that means it is not a solid axle in the back but independed suspension?
Yeah, I’m confused, the pictures I found of the Supra differentials look nothing like the truck. It’s definitely a solid rear axle and not Independent. Front is IFS
Looked up the part diagrams and a LSD option is listed:
Still don’t know how to tell which differential I have though, I guess I could jack the truck up and give the wheels a spin? If they spin in the same direction that means it’s lsd correct?
Also found the part number for the LSD differential assembly, it cross-references with the following North American Land Cruisers equipped with LSD differentials:
01/1990-12/2006 TOYOTA LAND CRUISER FJ,FZJ,HDJ,HJ,HZJ,KZJ,LJ,PZJ,RJ7*
Really curious now.
Edit: Going down a rabbit hole of internet searching now. Strangely enough it sounds like the Toyota Supra differentials are one some way the same or very similar as used by some Toyota trucks. Someone posted this:
“Here is some info I got on Supra Torsens:
The Torsen diff is a standard fitment to all 6 speed MKIV's, a lot of the Auto twin turbos and you'll even occasionally find it on a naturally aspirated Supra. You can tell if your Supra has a Torsen diff by reading the Trans/Axle code on the Engine Tag which is situated under your hood. The last letter of the 4 character code (eg. B03B) denotes the diff type which is "A" for a std diff and "B" for a Torsen diff.
The Torsen (TORque SENsing) LSD (Limited Slip Diff) works quite differently to the TRD LSD. The Torsen is a Torque Multipling type of diff with a multiplication ratio of around 5:1. What this means is that whatever torque can be sent to the wheel with the least traction, it can send up to 5 times that torque to the wheel with the most traction. Its biggest advantage is that it can do this extremely quickly and doesn't ever lockup the ratio, but is continuously "sensing" and adjusting the torque between the two wheels.”
