Torson diff lock

[Ranger Dolly]

How can I identify the torson diff lock on a 2009 ranger fx4 with a r8 axle

A Torsen differential doesn't lock, it's a limited slip unit- as I understand it, it's the best one for street use and probably off road but not for drag racing. The tech library may have more info. If you question whether it's a Torsen, pull the cover, if you see clutches it ain't.

Thanks for info and after reading many posts I think this is correct and the r8 axle is a very good off road set up. Just spent a couple days driving on snow and ice and my Canadian rig has very good traction.

The Torsen rear axle in Rangers is the large bearing, so the flanges on the ends of the tubes are larger than on all the other Ranger axles (which are small bearing), so there is no need to pull stuff apart. The only way a Ranger got a factory large bearing axle is with the Torsen diff.

Thanks and I am very pleased to learn my new to me Ranger has this robust set up

until 2010 and 2011 came along. they have big bearing, big disc brakes, 28 spline open diff rear axles. but no provision for the tone ring & it's sensor.

Just a tech note, 2010-2011 diff will accept older carriers. Stuffed a 1994 LSD carrier in my 2011 because I'm too poor for a torsen. Fit just fine when I swapped ring gear and took the tone ring off.

From a 28 spline axle?

I had a 2010 2wd that would get stuck on a wet leaf

Yep. 2010-11 is same spline, just different bearings, tubes, and brakes.

Good to know, I've never actually taken a good look at a 10 or 11 Ranger...

The one I have is an 09 fx4

The axle is just different enough that you have to be careful what you get for it. The differential itself is pretty much same same with any other 28 spline axle aside from the bearings.

The brakes are pretty much unique to the Ranger from what I’ve seen. The Explorer Sport is close but the rotors are non vented. I haven’t seen the brakes on a regular Explorer to say if they are the same or not. It’s possible they have the same rear disc brakes.

the 10-11 also have the boss for the watts link pivot. It wasn't threaded on the one I regretfully purchased.

Torsen is 31 spline
