One of the issues I worried about, needlessly as it turned out, before putting Powr-Lok LSD's in the Oka was potential steering on issues. The difference with the Oka though is that there's 1.5 ton (minimum) on the front axle (Dana 60) which tends to help settle pointing in the right direction issues. Rear axle is Dana 70.
As it turned out no problems at all, one of the best 'set and forget' mods I've done. Progressive take up/release no harsh Detroit Locker type action, none of the pain of air lockers, a minimum of fuss and works a treat.
But I reckon the turning circle has increased, I haven't measured it, it's just a feeling. With the lighter Landy is there a greater tendency to steer on ?
If it sounds like I'm a bit paranoid about 'steering on' it's because I am. Happened to me many years ago in my old SIIA (with open diffs :o) coming down from Aberfeldy to Walhalla (very steep drop off). Fortunately I hit a tree.
Thanks Deano:)
I'm not familiar with the Powr-lok, but a true-track is a torsen diff which won't drive a vehicle straight ahead. The detroit lockers are a ratchet type which definitely can.
When I put a Truetrac in the rear it made absolutely no difference on road.
Infact I wasn't sure it was even working until got off road with my axles crossed up into a position where I would normally lose traction.
When I put the front one it I could feel something different immediately, the steering felt a lot tighter but in a good way, like there is no slop anymore & the steering is a lot more posetive. The steering won't pull straight unless you want to go straight, it just goes where I point it. Even If you change power going around a corner on the road its a little quirky but no big deal , there is no big oversteer / understeer effect.
The truetracs have no effect on the turning circle, I've got my stops screwed all the way in & uturn is unchanged.
But if you don't keep the tyre pressures even on the front you will notice it pull to the side with the leak, which is great, I never noticed I had a low tyre before until it got down to about 20psi , now I know straight away .
And off road it has completely transformed the 110 to another level !!
Power-lok is a Detroit locker, have you driven rovers with detroits or torsen style lsd?Quote:

Who wants to portray an image? I'm to much of a *insert 4 little word of choice* to bother about an image:)
I have a Quaife in the front of my RRC and a Maxi in the back.Quote:

I used to notice a very slight tendency to resist the initial turn on curves, but since my new steering box, this is reduced to virtually nothing. AFAIK there is no increase in turning circle on hard or soft surfaces.
Now with the Maxi engaged things are different.

As far as diffs go I'm not a fan or Nissan or salsbury diffs simply because of thier size,yes they are strong but going from rover diffed series vehicles to a sals defender I found it a PITA.I used to 4wd around Appin and Wedderburn south of Sydney were it's all sandstone and the amount of times my sals got caught were's my mates in series/RRC's etc didn't was supprising,my Tdi sits on 255/85/16 tyres were's my TDCi sits on 235/85/16's and the P38 diff still has 20mm more clearance than the sals even though it's running the smaller tyre.My choice out of them all would be a rover/P38 diff with a hypoid center with a CW&P/axles/CV's made to Ashcroft spec.

Just for clarification the Quaife diff is a Torsen diff ( for Torque Sensing)
the same as a Truetrac
Brands of Truetrac are depending on market Eaton / Detroit / Tractech - NOT to be confused with the Detroit Locker or SoftLocker which are completely different.
A good spiel on the Qualfe here
Differentials - Quaife Engineering
Also be aware Front & Rear diffs are different - you have to specify what you want as the helical spiral gears are opposite cut.
Apparently not with the Quaife as I asked them before I put it in the front ( reverse rotation) and they said it will work fine.Quote:

My question
I have a Quaife differential fitted to a rear differential centre for aRange Rover Classic which I plan to install in my FRONT axle. Can youpease advise whether it will perform properly in this role , as thedifferential will be turning backwards compared to rear axle operation.Regards Philip Armbruster

These will work perfectly well reversed Phillip.Len Kind regardsLen UnwinQuaife Technical Sales
