1st front and rear diff change

Well the time has come that the odometer is about to roll to 60k. I’ve pretty much done everything by the owners manual since owning the 2016 Tacoma Sport at 20k. I haven’t off tossed a whole lot or put it in 4x4 expect once a month to keep her lubed up. My question is should I take it to the dealer for the rear differential due to the TSB (https://static.nhtsa.gov/odi/rcl/2017/RCMN-17V285-0727.pdf). I’ve never noticed it leak but what if it’s done leaking because there isn’t any more oil? Also would like to see if they could do the TSB for delayed Park, Drive and Reverse.

What’s the great TW think?

 

take to the dealer for the TSB and have them check the fluid in the rear then change the fluids yourself, i did the front/rear and transfer case all in under 1.5 hours taking my time, not a big deal....plus the dealer will charge alot for it..

 

Can they measure it without taking dumping it?

 

I wouldn't even consider letting them touch my truck for that nonsense. Put a torque wrench on the 3rd member bolts then change your fluids and sleep well knowing it's done properly.

 

Take the fill plug out and stick your finger in there. Fluid level check done.

 

Yes, this is about the only way.

If you want to be exact.

The oil level should be within 5 mm (0 to 0.20 in.) of the bottom of the filler plug opening.
