Diff Lubrication For The T

[Johnny G]

There's been a couple of threads that visited the DIFF OIL issue - but not many.

So - with all the combined experiences that we now have - I want to throw up the following 2 questions....

A - How many K's should a T do before a Diff Oil Change??

B - What replacement oil goes in?? Standard?? Change to something like Redline 80W140 or similar??

What are you using?? and DOES IT WORK???

Tx for the interest in the oft neglected "back end of the beast".

I done mine at 20000km dont know if it needed it or not but did it anyway, used castrol saf-xa 80w 140 with the sturaco additive from ford. Done nearly 12000km since oil change and didnt notice any change from before (not any noisier etc)

any of the recomended oils will be fine-your manual tells u whichj ones. I use teh castrol saf-xa aswell. One thing I should note-in my manual, there is a typo making the say saf-fa or something like that. is a full synthetive oil & quite expensive I think we retail it at around 28 dollars a litre & trade is around 18 bucks a litre. The additive is also a little hard to buy through ford as most spares departments dont stock it, and service buy it in specially. Penrite sell a ford diff additive called limslip which is the same stuff, I think the spec is 72980 or something like that, again it says this in the manual.

and also in the manual it says to replace your diff oil every 7,500km for frequent highway driving. I replaced mine cos of the common diff whine at 90-95 kmh & found the oil had a fair bit or metal filings in it and replaceing the oil made no difference. Have not bothered going to ford cos by the sounds of it, a replacement diff might be worse!

Hey guys,

If you using the Castrol SAF-XA 80W-140 and not the old 75W-140 you don't need to add the friction modifier. It's already added to the new 80W-140 oil.

When I first changed it, I was told that the current batch of oil available at the time didnt have the additive added but castrol were in the process of doing it to future batches, it was about 7 months ago. The additive wasnt that cheap either so its a bonus now, thanks for posting up the doc

Great Info Adamxrt.....well done

[Adam]

No worries!

That's what this sites all about.

[Johnny G]

Ditto - great work Adam. Doing a flush and change next week..... figure the cost of the Castrol outweighs a couple of well known others - as it'll be about four changes of it to one of theirs.

Specs for the new formula SAF-XA look spot on.

[Johnny G]

WELL.

that's been an interesting afternoon

The lubricable contents of my diff - at 34,000ks would be best described as .

Whatever our dear friends at Ford put in it originally had completely served it's time - it was burnt, stinking, rotten and black.

In went the couple of litres of new SAF-XA, and the whiney repercussions from the rear end have gone. Exit stage left.

Recommendation? 20,000k's max, and change it.

I changed mine at 22,000. Mine wasnt really that dirty, never had any diff whine through mine. I used some penrite 10/10th's oil with the ford friction modifier. Didnt notice any differnce, still got the dreaded diff clunks and clinks! Glad is doesnt whine!!
