was searching for my vehicle, it is a 2017 Land Cruiser with a 5.7 L engine and found these products all on one page:

https://www.searchforparts.com/oil-c...er-5.7l-3ur-fe

the oil I am not concerned about, I saw on this page the other products, like differential fluid? The front and/or the rear? after seeing this I started to research and now I am confused. too much info out there, tons of videos, so do I really need to mess with it? My Land Cruiser has 51,000 miles or so on it and I have no idea where the owner's manual is.

Also, after browsing this forum I feel that I can get a better answer here and not by doing searches. Thanks!

 

Try Helm, Inc in Michigan......great customer phone service. They did all the toyota shop manuals in 90s etc, so maybe still do....i bought 92 pickup books from them in 2019...about $100 for 2books delivered. 5star deal....
Factory books are awesome...chilton are almost worthless/ inaccurate!!
