Diff/Gearbox oil change

Thanks guys, just confused me as the comma site only suggesting the gl4 oil for the transfer box and no suggestions for the gearbox at all!

Don't worry about using fully synthetic GL4/5 oil in the gearbox, although only GL4 is specified.
I went into this in detail with the technical dept. at Morris's. Because their 4/5 is fully synthetic, it is blended with different additives to bring it up to spec.
No damaging sulphur is used in F/S, it is the sulphur which provides to the extreme pressure element in GL5 gear oil, but if this grade is used in a D22 box the sulphur will corrode the yellow metals in the box eventually wrecking it.
So using F/S GL4/5 oil will give the best of both worlds, proper oil with superior load capabilities.
I see from your other post a query about LSD diff oil, the sticker says it all, use only LSD oil in the rear diff, Comma make a very good one, most of us here us it, in fact my local Stealership use it.

I've just done some oil changes today, does it matter if I put LSD oil in the front diff, its the right grade, the additives shouldn't matter should they?

Courtesy of Wozizname....

Engine oil and filter replace every 6,000 miles (every 12 months if you don’t cover the mileage). Engine oil, 10-40W semi-synthetic.
Grease all prop-shaft joints every 6,000 miles where fitted (every year if you don’t cover the mileage). Normal LM grease.
Air filter, change every 18,000 miles (3 years if you don’t cover the mileage).
Fuel filter, change every 18,000 miles (3 years if you don’t cover the mileage).
Brake fluid change every 36,000 miles or 3 years if you don’t cover the mileage. DOT 3 or 4 rating.
Rear LSD oil change every 36,000 or 3 years BUT if towing or used off-road quite a lot then every 18,000 miles. Use only LSD specific Hypoid oil. 1.3 ltrs.
Gearbox oil replace every 54,000 miles. SAE 75-85W GL-4. 5 ltrs.
Transfer box oil replace every 54,000 miles. Dexron ll or lll. 2.2 ltrs.
Front axel replace oil every 54,000 miles. Standard SAE 90W GL-5. 1.3 ltrs
Inlet and Exhaust ‘rocker’ valve clearance adjustment every 18,000 miles. With engine warm adjust to, Inlet and Exhaust 0.30-0.40mm (0.012-0.016in).

LSD in front maybe to thin an no good,but I'd bow to greater knowledge of Chris and some of the others

AFAIK
Front diff has a SAE of 90W rateing
Rear diff LSD has a SAE of 140W rateing
Both are GL-5 do not use a GL-4 in either of them at any time :!:

Well put in LSD oil as per handbook at 80w90? Front and rear diff

trooper · Nov 20, 2012

Thanks for all the help on the oil specs etc for the D22, but i'm trying to do the gear oils at the mo but where can you get the right grades? LSD oil no probs got that but can any of you guys recommend a supplier for all the rest is it shop around and 1 from here, 1 from there? also do any of you peeps know how Nissan themselves stack up price wise cause i'm considering just going to the dealer.
Any help would be good as i'm having a mare of a time trying to find all the right oils.

If look back one page Chris Vince posted about Morris Lubricants.
They have online sales and a list of stockists.

As listed in Spirit's posting

"Rear LSD oil change every 36,000 or 3 years BUT if towing or used off-road quite a lot then every 18,000 miles. Use only LSD specific Hypoid oil. 1.3 ltrs.
Gearbox oil replace every 54,000 miles. SAE 75-85W GL-4. 5 ltrs.
Transfer box oil replace every 54,000 miles. Dexron ll or lll. 2.2 ltrs.
Front axel replace oil every 54,000 miles. Standard SAE 90W GL-5. 1.3 ltrs"

Or look at this 'lifted' page from the workshop manual
[attachment=0:2hpi1ifi]D22 Lubricant chart.png[/attachment:2hpi1ifi]
Where it says about 10% friction modifier I'd say :adminfinger and get a LSD specific oil designed to do the job correctly :awesomework

I own a 2WD Frontier D22 with a TD27 engine. The correct grade of oil Nissan recommends is in the owners manual I believe it's 80W90. I am located in the Caribbean region not sure if the same grade is recommended for other regions in the world.

I use Amsoil Synthetic Severe gear oil 75W90
2 Quarts for the gearbox
1.5 Quarts for the Differential.

Hope this is helpful.

2big2race · Apr 20, 2013

Hi guys... Many thanks for the replies. That page from the workshop manual was most helpful.
I must make time and get that manual...

GazNav D22 · Apr 21, 2013

Reccomend getting the manual mate, but its the experts here that helped me understand what it all meant. Anyway I changed the front and rear diff oils yesterday with the correct oils (used comma brand), which my motor factors stock but nothing come up on their computer for our trucks, so as far as buying them, make a shopping list from this thread!

Just had that minor setback yesterday of discovering the sump plug washer from the engine in my bowl of waste oil as I was clearing up afterwards..a few choice words and a hot swap later and its all good!

That oil in the diffs smells nasty, and has some additives that can cause allergic reactions so wear gloves and be careful

Hi Bounce
Done exactly this job last weekend so have the info :clappy:
Front axle SAE 140W API GL-5 (2 1/4 pints req'd). I couldn't get a straight 140W grade but put in SAE 85W/140 grade.
Transmission SAE 75W/85 API GL-4 (8 5/8 pints req'd).
Transfer box DEXRON ATF III automatic transmission fluid API GL-4 (2 quarts).
Rear axle Hypoid LSD oil API GL-5 (2 1/4 pints).

DO NOT USE GL-4 in GL-5 and visa-versa where recommended as this will damage these units :!:
I found the front axle, gearbox and transfer box oils in good condition after 70K miles but the rear LSD oil was VERY black and burnt. This LSD oil should be changed every 36K miles BTW :shock: Also do not use any of these so called 'oil modifiers' to change gear oils into LSD oil as they're a load of ***** IMO, get the right oil for the job :thumbright:

My motor factors supplied me with GL-4 semi synth 75w 90 for my transfer (54 plate), no mention of dexron ar ATF on the bottle? Is that ok as its the same thing that comes up on the comma site?

I used the same grade in my transfer box, I tow a 4 wheel trailer a lot, and went for the extra heavy duty protection of a proper gear oil rather than an ATF based lubricant.
The workshop manual states either type can be used.
My thinking was that there are no gears as such that require changing so a thicker oil won't affect driveability.
I used GL4/5 fully synthetic in the gearbox, made it much smoother and slicker on the changes.

All done mate, I also opted for semi synthetic 75w90 GL-4 in both the gearbox and the transfer box, and all changes are smooth, and I like the idea of the heavy duty protection as you said

Good, good :thumbleft: You can forget about doing them again for another 60,000 miles :thumbright:
Keep yer eye on the rear LSD though Gaz if yer towing/off roading because the oil gets knackered before the 32,000 mile recommended replacement period :wink:
Done mine again at 25,000 because I popped out the filler plug, stuck my finger in the oil and it was black as a hat :shock: I reckon it's down to towing and other heavy loads.

GazNav D22 · May 9, 2013

Mine was as black as a witches tit too mate, it's too easy to do to leave it more than 20k for the sake of about £8 of oil, so will be keeping an eye on it

diggerdale · Jul 7, 2013

All done ! the oil was a bit more expensive from my local dealers but available . I found that using an old 5ltr garden sprayer without the lance was the easiest way to pump the oil in the gearbox and the front diff the others were ok with the bottles .

a drill pump works great for this, you can pick them up for around 10£

hi i'm a bit confused just got back from the motor factors,
and on there system (comma oil) it states 75W90 GL5, for front diff and main gearbox,
so they gave me Comma SX75W90 GL-5 (semi synthetic)
But this is not right is it?

chris vince · Mar 28, 2014

Personally and from experience, I would swop it for fully synthetic in the gearbox, the changes will be as sweet as a nut.
