Some diff questions:-
Would my 96 4.2TD's rear diff be LSD ? Front is just a regular diff, right ?
What oil do you guys use in front and rear diffs (brand, viscosity etc). Manual says SAE90 for rear, when LSD, and doesn't make it clear whether either or both have LSD.
Where can I obtain Castrol oil in this country ?? Only found one supplier on the web. Halfords certainly don't stock anything other than Castrol engine oil, and only one litre containers of their own brand of gearbox oil.
I checked the rear diff oil last weekend and it was nice and crystal clear. However, the front diff oil was contaminated with what I presume is steering knuckle grease that's probably entering through a bad axle seal.

Have you got locking diffs? Have you got the rotary diff lock switch on the dash to the left of the steering column? If so, then you don't have an LSD. If no locking diffs, then there should be a tag on the diff to tell you if it's LSD.
Normal diffs use 80W/90, and the transfer 75W/90. I just get mine from the local motaquip factor. You can get a 25 litre drum of motaquip engine oil for £30 as well.
The front diff oil always seems to go black, possibly from the birfield grease. But in theory it would be more likely the diff oil getting into the birfields and then leaking out around the hub, so who knows. I simply change all the fluids every year, including coolant and brake fluid. None of the fluids cost much in real terms, so what the hell. |

It has difflocks with the rotary knob you describe.

I too found my front diff oil 'contaminated' with moly grease from the knuckles.When I unscrewed the filler/level plug I noticed a hissing sound.Not sure if it was air rushing in or built up pressure getting out but when I checked the breather tube it was blocked solid! This could obviously help moly grease get past the seals if the pressure in the diff casing dropped in cold weather.Check those breathers!!
I filled the diffs & trans.. with some 80/90w carlube oil from the local car spares shop.So long as it's manufactured to the required spec you'll not go far wrong.
I agree with you DaveN.I can't see the point in paying £60.00 for 10 litres of the best fully synthetic oil unless you're going 10-12K between oil changes.Extended drain intervals was one of the main design briefs behind the development of fully synthetic oils.I reckon changing fully synth every 4-6k you're just wasting money. _________________ Phil

Where is the breather tube located ?
I heared a hissing noise at the transfer case when the fill plug was removed for checking the oil level. But no hissing noise when removing the diff plugs. I read about this somwhere but can't remember where !!
Here's an article on contaminated diff oil, and there's a link in this link to breather hoses.
