I want to change the front differential fluid to Synthetic. I need to know what size and type of tool is required to remove the fill plug on my front differential..

Any 3/8" socket wrench. (no socket, just the wrench).

That's what I thought also Mike, I knew the rear diff uses a 3/8 drive but I'm at work so I couldn't be sure about the front.
A 3/8 breaker bar might give a little more leverage.

Given what MikeZ says, prob. similar to http://www.titantalk.com/forums/show...0&postcount=20


Service Manual states front/rear routine maint. much the same, except has this statement re rear:

If using the vehicle for towing, the rear final drive oil must be replaced every 3000 miles or every 3 months, whichever comes first.

1. Remove the filler plug.
2. Remove the drain plug and the final drive oil.
3. Apply sealant to the drain plug threads.
__Use High Performance Thread Sealant or equivalent.
__Nissan North America Part No. (USA): 999MP-AM002P
__Aftermarket Cross-reference Part No.: Permatex 56521
4. Install the drain plug and tighten to specification.
5. Refill the rear/front final drive with new specified oil.
6. Check the oil level.
7. Install the filler plug and tighten to specifiction.

Final drive fill/drain plug torque:
27 N·m
2.8 kg-m
20 ft-lb

Front final drive fluid volume, per service manual:
1.6 liter
3 3/8 US pint

But, would fill to bottom of fill opening.

Alright, extreme noob question (forgive me for asking this). I'm going to change my front differential fluid here shortly and I'm wondering where exactly the front differential plug is located in reference to the engine oil plug. Is it more towards the front of the truck (ahead of the engine oil plug), or is it more towards the middle of the truck (behind the engine oil plug)?

I know you're thinking this is crazy for me to be asking this, but this is going to be my first time changing front differential oil. Hey, we all have to start somewhere right? I've changed every other fluid in vehicles, just never a front diff, so cut me some slack...


BTW, I'm replacing it with AMSOIL Severe Gear 75W-90 (only the best )

If you happen to have a picture of the location of the plug, that would greatly help out. Thanks fellas.

Bump back to the top. C'mon people, I know those of you who changed your own can tell me.

It's on the axle. The axle is the cylinder that the wheels are connected to, follow it from the wheels to the middle of the truck...you will see it get big in the middle...that is the differential. The plug is in the bottom. This plug will just have a square hole in it...not a standard hex hole, or bolt.

To remove, use your socket wrench without a socket.

Actually, it's 'pop' back in western PA where I come from too!!!


And while the technical name for it might be a socket wrench, I've never in my lifetime heard anyone say "Hey, would ya hand me that socket wrench", but I have heard "I need an extension for this 3/8" rachet", etc.

Sorry, guess it struck me as 'odd' being called a socket wrench.

We use pop here too...
