Looking back through the past posts there seem to be a wide discrepancy as to what you should fill your 5 speed manual box up with. Ford drivers 'manual' states ATF in the diffs with LSD additive in the rear. Actual book spec. for the gbx and tx box is in Ford'eeezz - so don't know what that recommends.

Now the search on here picked up both ATF and EP75/90 gear oil as tx and gbx options. Which is it? ;)

On the same vane I just filled the gbx with EP90 GL5 and despite the oil capacity stating 3.5l I managed to get 5+ in there. Is the tx and gbx oil connected?

Cheers all :smile:
 
Yes my Mav manual says the same but it does quote ATF to a specific ford standard, this must be hypoid gear tolerant, most aren't.

I thunk most people us the Nissan standards as after all nissan made them.

Box and trans GL4
Front diff - GL5
Rear diff - GL5 LS
 
Cheers for that Hummer.

Lubricant that dropped out of the gbx 'smelt' like EP anyway but the quantity seemed far higher than 3.5 litres.

Also forgot to mention this is the later round headlamp model.

If Ford had built it GF would not have bought it LOL :roll:

Early gearboxes held 3.5ltr, the later one holds 5ltr
My old 1993 held 3.5 and the 99 I have now, holds 5ltrs.

Its not the best thing to put GL5 in the transmission the extra EP additive can eat / corrode any bronze components.
 
Cheers Jerry. So a la Series Landrover gearboxes then? White metal bearings etc. It was 50% GL4 and 50% GL5. So I will plan to dump and swap out soon.

Thanks for the volume confirmation. That's one hell of a lot of oil and a good job I had enough to hand?
 
Just picked up 10 litres of GL4 for the tx and gbx. So in keeping with my skinflint attitude I'll be draining the gbx GL5 out and using that in the front diff :wink: If I can get some LSD additive the rest will go in the rear.

Well an update on that. The GL5 dumped from the gbx had turned to foamy treacle in under 20 miles. Looks like there is more water in the box than I thought (car had been in a flood earlier in the year) and it just didn't show up with a cold box. So that is all going for recycling. that was a waste of 5 litres!

Both Tx and gbx filled with 80/90 GL4 and shifting much nicer than before says she who must be obeyed. LOL :twisted: :roll:
 
Next on the servicing list is:-

  • Rear diff - Millers CRX LS 80/90 (on order)
    Front diff - 80/90 GL5
    Remove intercooler and clean with solvent - never been done
    Grease front/rear prop
    New air filter - full of feathers. No pheasants though (on order)
    New fuel filter
Other than that there is:-
  • Drivers side front electric window doesn't work
    Clicking from front axle under heavy full lock load - CV's/front FWH ?
    Clutch biting point very high - original clutch as far as we know. Adjustable?
    Pollen filter - change/clean/remove?
    valve clearances
    Front brake condition check. Poor brakes compared to the Jeep (might be a Mav thing?)
    Original shocks all round - Lot of wander from the front under heavy braking. Could do with a change at this milage?
For a vehicle that was receiving an annual service from a non-franchised gge it's never ending :smile: .....or am I just being picky? :wink:

Look on the bright side, by joining the club and doing the job yourself least you know it's been done properly :wink:
Have a look in the workshop downloads as you'll find quite few items in there that well help.
 
Exactly Rossco ;)

My impression of most garages is that you pay them money; they do half a job and the half they do is done to the level my cat could have managed :lol: So better off doing it yourself 8)

Done a good download trawl and have them all backed up for later jobs. Unfortunately I'm in Singapore at the mo sans Maverick so no chance of getting any of the list x'ed off at present :wink:
 
does back diff need to be lsd oil or additive ???

the book in 2 motorfactors i went 2 listed 80w/90 or ep 90 for everything
 
As far as I know it has to be LSD oil only :smile: If you have a look in a thread I started a while back noisy rear diff the oil others & myself have used is listed their & it cost me £4 a litre :smile:
 
Lsd oil is normal gearbox oil with an additive you can buy it seperately or buy it ready mixed i just prefer it ready mixed you know its right then.
 
Just done my rear Diff today,it is definitely lsd oil..!! now for the front diff and gear box!! :lol:
 
Well the Millers LS oil has arrived at home, apparently so that's a job for next weekend :lol:

Johnson I looked for the additive but had trouble finding it (or LS oil from most auto factors!) so went with the pre-mixed option. Bought it from these guys in a 5l can. Always useful to have a bit of spares and between buying 3l and 5l there was hardly anything in it.

Friction plate type, so they lock up fairly well, you can get a gear type (atb etc) for the front diff but can't really see the point as they don't work when one wheels in the air when you most need them.
 
depends wot make i have a ap racing 1 for a 205 rally car which doesnt do that (thankfully)

there is away too make them lock just left foot brake it'll load the spinning wheel and send torque to the 1 with grip have been told quaife sorted that problem out with thiers (on rally cars atleast) by altering the pre-load.

but anyways just wondering wot to do with oil i bought catalougues definatly said normal 80/90 or ep90 seen in black n white mmmmmmmmmmm!!!!!!!!!!!!

wot u's reckon???? should i get some additive??
 
You're motor factors catalogue is definitely wrong, the Nissan workshop manual states LSD oil. If you can then get some LSD additive, otherwise just get some LSD oil and save what you've already got for a further front diff change. Even Nissan/Ford dealers have been known to be putting the wrong oil in the rear diffs let alone the independents, won't matter to 99% of owners but if you want to us your truck away from the black stuff it will.

I know about the left foot braking trick but that really doesn't cut the mustard off road.

Have to say I wasn't aware that AP did a diff, never heard of it.
