Hi Folks - long time, no post!

If the rain stops, I'm going to change the gearbox and diff oil on my wife's '02 2.0 NRG. I've got the GL5 spec oil for the box and diff, but I was wondering if the RAV had LSDs??? All I know for certain is that it's permanent 4wd, but I don't know about the diffs. Also, is the front diff integral with the gearbox on this model? I see from the Toyota Tech site that some models have a separate front diff.

Thanks folks.

wotdya mean IF the rain stops? Its bucketing down in Lanarkshire so it must be wet in Ayrshire! Thats what supermarket carrier bags are for - rain-wear!

No limited slip diff's! The transfer box is attached to the front diff permanently in such a way that between the rear axle diff and the front diff they do away with the need for a third diff and transmission wind up between the two axles is eliminated.

Keep in mind that you need to change the rear diff oil - plugs shown here;





The gearbox oil (which includes the front diff');





..........and the transfer oil;





Here are the specs for the oil (ignore the auto box).



Good luck.

Thanks anchorman. I've got 80/90W for the back diff and 75/90W for the box/front diff (both GL5). I didn't know about the transfer oil and the links haven't shown up. Can I be a pest and ask what the grade is and what capacity it is???

No probs

It is 0.9 litre of GL5 straight 90 but it shows 80W/90 for low temp operation. If you have that it will be OK.

If you pm me with your email I will send you the service data sheet.

Cheers

Cheers guys, but I'm still a bit confused. I've got the 2 page pdf of the service data sheet, but I'm still wondering about the transfer oil. In the second bottom pic of the service sheet it seems to indicate that it doesn't apply to manual boxes (but that auto's get 0.9 litres) as there is just a line next to the manual box symbol.

Looking at the gearbox capacities I see that the 4wd box takes 1.5 litres more than the 2wd box. I was putting this down to the transfer oil being integral with the box oil???

The pics are very handy (they didn't show up at work, but are fine at home). A very clever person once told me to loosen off the fill plugs before draining any fluids as there's nothing worse that draining oild and not being able to fill it back up again!

Thanks for the link. However, I think this is for the 4.3 and anyone reading this should not be tempted to use 75W/90 in the gearbox or selecting gears from low ambient temperatures will be almost impossible.

You are right about the data sheet but as far as I know all with 4WD have a seperate transfer box and I have crawled under both petrol and diesel variants and changed the oils. I can only think that in error they have shown the spec' for FWD only models???

It is easy to check. The transfer box is just about under where your feet go when driving - stick your head under and look!!!

Ok, I'm definately being a pest now anchroman. In a previous post (a reply to jospom?) you state that 75W/90 SHOULDN'T be used in the gearbox. That's what I've bought as I'm sure that's what the spec sheet said. Do I need to take this back to swap it for 90W??? Fortunately, I'm friendly with the guy on the counter...

No mate, you are OK with 75W/90 for your 4.2 - that is correct.

The info that jospom kindly supplied suggests from the capacities of 5.9 litres for the engine and 2.1 litres for the gearbox are for the 4.3 with a 2.2 D4D and a 6 speed box. In this case straight 75W should only be used in the box or gear selection problems will result in cold weather. The best supplier for this oil is Kingo.

Thanks anchorman. I think I've also sussed out the confusion with the data sheet pdf. Forgive me, but I've not got it in front of me;

Gear box and front diff are 75W/90 and it takes 3.4 litres
Transfer box is 80W/90 or straight 90 and it takes 0.9 litres. I think the pdf is supposed to show that it's the same capacity and grade for both manual and auto boxes - but it is confusing!
Rear diff is 80W/90 or straight 90 and it also takes 0.9 litres

Pheeeew.

It is confusing. To me it looks like the transfer box is not applicable to the manual box but I don't know why???

[rpaterson]

I always thought that the Toyota Production System was supposed to fix problems!

Ah well, I'll drop the fluids next month and see what the score is...

[rpaterson]

Wow, did the jobs yesterday. Nightmare. I'm definately buying some form of fluid pump before I change any other fluids!!!

They were all a doddle to drain. Obviously the engine was a easy to fill, the gearbox wasn't too bad, the diff was 'OK' but the transfer box was horrific. Why don't they give you enough space to tilt a 1 litre bottle easily??? I resorted to using the actual fill plug on the transfer box along with a length of garden hose cable-tied to the strut brace!

Never mind, four years (I think) before it needs done again!

ps, don't even think about trying to push gear oil through windscreen washer tubing using a big syringe when the outside temp is 2 degrees C.
