Rear end question

What kind of rear end does my 2010 Prerunner SR5 have? Is it limited slip
or what they call an "open" rear end? I asked this question on the 2nd generation site and no one must have known. I have the towing package, 16" wheels, and automatic tranny.

 

If you still have your window sticker it should say on that. I know that my 08 Sport says LSD on the rear axle. You could probably look there also.

 

Thanks for the answer, whippersnapper. So is what I have the same as what used to be called positraction? I live in Oklahoma and often have to go
through water holes to get to my fishing spots. The soil is sandy so there's
always a firm bottom, but it can be a couple of feet down. My old '78 GMC
short bed non-positrac would plow right through, but I had some pretty aggressive mudgrips. I skeptical of the stock Dunlops on my Tacoma and am wondering if the rear end setup I have will be of any help.
