06 Taco Prerunner Locking diff what fluid

Been searching the internet for this info but its hard to find info on a locking rear diff taco but I am going to be changing my rear diff fluid soon and it has a locking rear diff what type of fluid do I need for it and do I need any sort of additive for it?

 

$30 Mobil 1 75W90 Mobil 1 104361 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

Mobil 1 75W90 Full Synthetic

 

any additive needed as with the limited slip?

 

right on thanks. Taco just hit 70K and I am going on a long road trip in October. Its getting some loving soon. Luckily I am a technician at a Ford dealer and I have access to all the tools I need to do the job my self just needed to know the fluid type, Fords dont have cool things like locking rear diffs

 

You said Locking Rear? If its a Limited slip youll need a conventional 80W90 oil with additive,synthetics dont work well in Limited Slips only in Locking Rears(TRD Offroad Package)no additive needed

 

Yes I have the TRD Offroad Package with the locking rear diff

I am at 70K miles I am going to be doing Spark Plugs, Rear Diff, cleaning my K&N air filter, oil change, and 4 tires within the next month. Cant think of any thing else it needs at the moment probably a throttle body service and fuel injector flush as well, I have access to all the BG flush equipment just gotta buy the chemicals

 

Mobil1 75W90 Full Synthetic, get 2 new washers from the dealership too you can only use the washers once,24MM socket and ratchet,torque should be 36 ft./pds.

 

this

 

didn't know it had one but would probably explain why my airflow is less than it originally was. added to the list

 

Drain and refill Auto/Manual tranny while you got the drain pan out,clean the throttle body yourself with spray and rags,forget Fuel injector flush drop in some Fuel injector cleaner once in a while and good to go.

 

Was gonna save the trans for 100k. I have throttle body cleaner and every oil change I run a bottle of cheveron with techron through it

 

Here is what my 70K mile cabin air filter looked like. And dont worry I took out the blower motor and cleaned out the AC case and put a new filter in

 

Toyota wanted 40 bucks for a Cabin air filter pepboys was 25
