You all have been nice enough to supply me with information regarding axles and ring gears. I have even benefited from the on line spell check. Now I would like to know if anyone knows the stock gear ratio and what kind of locking diffs. are available for the stock axles in a 95 Discovery.
Thanks

Detroit and ARB
Don't run lockers w/ the stock axles |

this should be a long one
in my opinion with a controlled well chosen line lockers will protect weak stock axles because you are able to use less power to negotiate tough terrain.
open differentials promote tire spin . Tire spin stores energy that very often when released suddenly such as one spinning tire gaining traction will overload that portion of the driveline causing a failure. |

There are several options for lockers in Rovers. McNamara is slowly becoming more popular. Truetrac makes a nice LSD (not the Stanley Owsley variation). Another option that is occasionally seen is the Toyota lockers. Surprisingly, the Toyota differentials are fairly easily put into Rover housings. The Toyotas, depending upon year and model are either cable or electric actuated thus negating the need for OBA. The McNamaras require far less air volume and pressure for actuation.
While stock axles can be used with lockers, it is not really suggested as when the axle breaks, sometimes, it wipes out the locker. If you wish to retain the stock axles, you are probably better off with a Detroit or Truetrac.
Perrone Ford has a Detroit in his Rangie with stock axles, perhaps he will weigh in on this and give us the benefit of his unceasing research.
Now, for my disclaimer. Why do you need the locker? I have yet to find myself in a situation where I needed one, and have ascended slopes with open diffs that those with lockers were unable to summit.
Peace,

Yeah Paul, I have been putting off locking my truck up for a while and Im sure I will do it some day but for now it is damn cool doing stuff open that I previously had to lock up for. |

lockers=control
its that simple
the breakage part shows up when guys start doing things they wouldent try with open diffs
these trucks have plenty of gear reduction to crawl why they did not have a factory selectable option is beyond me.
one you own a selectable locker you will never go back.
well thats not really true...you will go back and forth locked and unlocked |

Thom, it is true, but...
consider the gazillion of load/unload cycles placed on the axleshafts with an automatic locker - the axles will work harden and become brittle.
to me it's open, TrueTrac, or selectable.
Paul, TracTech makes Detroit and TrueTrac (and some others.
by the way, i was really surprised to see the TracLoc (don't know who makes it) in the D44 to be surprisingly tight. Maybe, whoever put it in forgot to put any oil in the diff (will find out soon)

peter,
I agree an automatic locker such as a detroit will put more stress on a daily basis. and I am not a big fan of them just for that reason.
now combine that with the negative of there less then perfect winter driving characteristics and I think full time/automatic lockers are not a good idea for a daily driver.
I am very excited about the new electrac from Trac-Tech having a mechanical LSD with the option of 100% locked is very apealing.

Ya, I like that one to Tom. Only issues is that it would be a really hard install into a Rover since the electic locking ring in installed onto the diff cover (which I believe is supplied as part of the locker) and our Diff covers are welded on. So you would have to drill, line every thing up just right. It would really hard to do. I was looking at that one for my Disco but, once I got a look at how it needed to be set up I went with the ARB. Now if ARB would make one just like it that would be pretty sweet. |

eric,
word is that ARB is currently in developement of a LSD air locker combination. so your wish may soon lock on command

Paul, Are you saying that you've never got yourself cross-axled? On flat terrain, I can understand your position, but I can't tell you how many times that if I had at least a rear locker I would have been able to cross that obstacle. |

selectable ARB, control offroad, no quirks onroad
LSD selectable ARB in the front would be nice indeed... |

I run a detroit out the back and a true trac gear driven LSD up the front stock axles 31.5" cooper AT all round.
My rig is supercharged and goes like the powers of piss. Did i mention the old man emu 2" lift and poly bags in the rear springs.
Point is that my rig will go allmost anywhere off road in a controlled fashion with my good self not having to worry about airlines compresser and hiting the switch that activates my locking ability.
Point 2 98% of all airlockers fitted will need to have annual maintenance as inveriably the little rubber o ring inside lets go or perishes cost $1 for o ring $300 labour to replace.
Point 3 I am only a simple australian on our tracks it can be quite common to encounter branches and or foliage that on a reguluar basis have been known to rip out your locker especialy when your going thruogh a bog hole and cant see the bastard.
POINT 4 When i drive i like to enjoy the scenery not my dash and or switch pannel that engages my lockers.
POINT 5 Detroit lockers are cheaper and stonger than the ARB product
POint 6 yo get the drift and it is kind of ironic as the ARB product is proudly Australian as i am and the Detroit option is American see you boys do get some things wright pardon the pun |

Blue,
LSD is illegal to use in every state in the US. I 'm not sure why you would use drugs to aid in you off-road prowess anyway! |

You have some good points Colin but a MAJOR downfall of the detroit is it's performance in ice and snow, which I doubt you get much of in Australia. I've gotten away with a detroit in the past down here in the south but the one time I encountered snow w/ it the experience was very scary. |
