2021 tacoma differential gear

Do/ should I change my differential gear fluid on my 2021 tacoma trd off road 4x4? I am almost at the 1000 mile mark.

i looked on the forums but cannot find any answers.

thanks all!

 

What does the maintenance section of your manual recommend?
Seem way too early to me.

 

You should change it every 500 miles.

 

I just changed mine for the first time and I have 85000 miles on my truck. It’s recommended very 15k miles or so to at least inspect but you don’t need to change it quite yet. For me my rear was fine but my front was contaminated. Probably got some water in it at some point.

Here’s a helpful thread:

lol nope.

 

The factory gears are forged rather than cut/machined, so don’t have the same initial break-in as aftermarket gears, where you gotta change the diff oil after 500 miles. No need to change factory fluid fill with factory gears so soon in the trucks life. Just follow what’s in the manual.

 

I just hit 1,000 miles in my 2021, it is a TRD Off-Road 6MT. I am going to be doing a road trip soon and I did a lot of hills, dirt roads, and used four-wheel drive during the break in, so I thought I'd go ahead and change all the fluids. I did this on my 2016 at about 5,000 miles. It was a mess and took way longer than anticipated, but I am really glad I did this, my notes are: engine oil had a fair amount of metal shavings and light brown tint; front differential fluid was clearly contaminated with a milky brown color and strong odor, substantial metal shavings on drain plug and in fluid; rear differential fluid was slightly contaminated with dark brown milky color, substantial metal shavings on plug and in fluid; transfer case fluid had medium brown tint and noticeable metal shavings; manual transmission fluid had a light brown tint and noticeable metal shavings. I am quite concerned about the way the front and rear differential fluid looked and how it was contaminated after only 1,000 miles. In comparison, my 2016 had no contamination but similar condition to the above. I replaced with the following: Pennzoil Ultra Platinum Full Synthetic 0W-20 and
