Do I have Limited Slip Rear Differential?

The dealer could not tell me if my truck has LSD. One guy was trying to tell me they never made Tacoma with the Yamaha package

One of the mechanics told me they never add LSD additive...they only put synthetic...

They told me Toyota doesn't have a LSD additive...anybody know the part number?

Needless to say I won't bring my truck there for the frame inspection...actually not sure which dealer in Ottawa, ON to bring it too....(open to suggestion)

 

I used 'Mobil 1' gear oil (75-130 in the back dif and 75-90 in the front) and it is rated for LSD difs too (ie. has the modifier included)

 

I have done that and they told me wrong . In fact I call 3 different dealers here in town gave them my vin # and they all told me that I had it. But When I did the jack the truck up and turned the rear wheels and one went one way and the other went the opposite direction then I new that I didn't. just my 0.02 cents.
