Just curious how often everyone is greasing their u-joints on their driveshafts?.... I have almost 25k on my 2015 4x4 CM. I usually grease up drive-line about every 8-10k miles. I noticed when i take my truck to Toyota for oil changes/services they don't grease the ujoints...AT ALL...EVER. My wife has a 2016 4runner, the dealer doesnt do hers either.
