Have I got a Hydrotrack Diff...?
Discussion
When my car was on the ramps the other day, I noticed a big sticker on my diff which said "HYRDROTRACK" (and some other stuff...)
I thought this was an option (and a relatively undesirable one at that..)??
I deffinately didnt spec one when I bought the car...
Anybody got any ideas..?!

Also very intrested, as my Tamora had to go back to the factory for various bits and pieces to be corrected. One of them was a leaking axle, the axle had a Hydrotrak sticker when it went into the factory but this appears to have gone and the axle casing is very different.
Mine was a 2004 Tamora but i did not specify a Hydrotrack?, are they really that benificial.

Whilst I understood the basics of a Limited Slip Diff, your post had me wanting to know more.
It appears the Hydratrak LSD is built and supplied by Dana Corp. They inherited the technology when they bought out BTR Engineering of Australia.
The following is extracted from an Ausie website
The Hydratrak limited-slip diff transfers torque in direct proportion to how fast the slipping wheel on the axle is spinning, rather than merely multiplying the torque on the slipping wheel. It applies the torque as a counter force to the wheel that has traction.
This improves cornering performance, especially in adverse conditions, and can result in a quarter-second improvement in a vehicle's 0-60 mph acceleration.
The Hydratrak design is similar to a conventional open differential, but with a cartridge-type fluid
coupling replacing the right-hand gearing. The left-hand axle shaft is connected to the internal hub of the Hydratrak coupling and left-hand side gear. A series of slots are machined into the hub, with each slot containing a single vane. The right-hand axle shaft is connected to the outer body of the coupling, which consists of the side gear teeth and internal cam profile.
Speed differences between the left and right drive wheels cause the hub to rotate, which, in turn, moves the vanes and transfers the viscous fluid within the coupling. This creates hydraulic resistance to transfer the torque between wheels, which is increased as wheel slip increases.
There you go....an its gotta be true its on the web...!
