Used this for 2 years without any issue before totalling my 97 4runner, my baby from day one!!!!, two weeks ago. The rack was worth every penny.....my $0.02...
BAD NEWS...............it was totalled on the 20th, rolled twice and she saved my life.....crushed a vertebrae in my lower back 50%....tons of pain right now. I will miss my trusty steed!
Flip the damn jiggle valve to the 6pm position and be done with it.......minimal work and time to ensure the correct engine temps........it's that simple really. Put on an incline and burp it............
Gonna jump in here and say the absolute best stuff I've used, and I've used MT-90 (it's very good), is the Amsoil GL5 75w110 Severe Gear lub in all my transfer cases and the manual tranny of the T4R. I will never use anything else period, just my personal experience and $0.02.
Best, most efficient solution?
