Q: Will it work for a 2007 Tundra 2wd rear dif?

I tried this is my 2007 Tacoma Prerunner with the mechanical limited slip diff and the clutches just wouldn't properly slip no matter how much friction modifier I added. I ended up throwing out some good money worth of oil and put cheap Castrol LSD gear oil in it and it worked fine. I don't think this is a bad product, Toyota differentials just do not like synthetic oil in some cases.

Q: Will this work for toyota rav4 awd 2016?

Refer to your owners manual. IF the application (transmission/transfer case) states lubricant per GL5 then yes, it will work great. If GL4 then look at Red Line ATF. NOTE: API GL classifications do not go up and down like motor oils (API SN may be used in SL spec engine). GL5 is totally different from GL4 and will damage synchronizer surfaces and or limited slip clutches if not applied correctly.

Q: Will this viscosity provide adequate protection for a 1971 C10 daily driver?

I noticed a difference when I changed mine out to this. I just used their mt90 for my manual transmission and it made a huge difference

Q: Lexus gs 350awd says 1.4qt 75w85 for rear and .7qt 80w90 for front diff. can i use this for both? have a bit of 80w90, can just buy 2 bottles.

I would recommend staying with the fluid recommended by Lexus. If it were me, I would buy one of each fluid required.
