hi just bought my first ute (cheers all round) but the slimey sales man told me the hydratrak diff is mean't to be locked all the time, is this correct or am I going to have to replace the diff as it shudders constantly when turning corners. p.s. It's the Longreach Outback 96 model

try changing the oil first that the most common prob in lsd diffs when the oil gets a little old. and no it's not ment to be locked all the time

The Hydro Trak Diff is basically a Viscous fluid diff, not a locker.

Oil change will not affect hydratrac operation, as they are a sealed unit. You could be up for a new coupling.

Thanks any idea how much I might be up for and is it a major job? P.S. Can you explain to me what a coupling is and how it works (if you don't mind) as I like to know how things work.
Thank you, Utegirl.

Basically the viscous fluid gets thicker as it moves, so as there is movement between the axles (differential action) the fluid resists different rotation speeds. When turning a corner the difference in speed is small so there is not much resistance, but if one wheel spins the difference is greater and the resistance builds.

my g/f put one of these diffs in her EF GLi (it is the 3.45 GT Hydrotrak) and we drained it before installing it and refilled it with oil that Ford recommended but unfortunately i can't remember what it was called!! all i know was it was about $50 for a litre!...i think it was Castrol SAFXA or something like that....

WTB, what sort of price do you guys sell hydratracks for?

WBT56

The couplings are easy to obtain, I think about $600 or so. The biggest problem is that one of the axles is a custom job (dual spline) to drive the coupling, and I am unsure as to the availability of these. Ben.
