I haven’t made a post like this since last year so I figured that I was due for another one of these. I have had two oil changes with different brands just to see how the engine oil analysis results would come out, had some of the Automatic Transmission Fluid (ATF) changed out, swapped out the u-joints on the front driveshaft, and had to have corrective maintenance performed for the first time ever when the passenger side rear wheel bearing started to go out. My heart just sank when I saw gear oil smeared on the brake backing plate. I can’t complain too much since nothing else has actually required repair or replacement on a 2008 model year truck. Anyway, here are the reports from men smarter than myself and associated photos.
Valvoline 0W/20 Oil Analysis:
Castrol Edge 0/W20 Oil Analysis:
Toyota World Standard ATF oil analysis:
The bearing seal just sort of disappeared off of one of the bearing caps on the front driveshaft forward u-joint so I had both replaced.
I was curious about how fat the truck had gotten over time so I went to a weigh station:
Lastly, here’s the part that makes me sad. $1200 later I had the wheel bearing replaced at Toyota of El Cajon.
