Maybe its time to change the fluid in your rear diff with some new friction modifier?
If it is your rear brakes dragging a bit, that makes sense to me as well.
Shot in the dark, but did you verify the correct fluid level in the transmission? Almost sounds like your torque converter was slipping or failing to lock up.
Actually now that I’m thinking I did get a “service throttle body” message after a few long cranking periods killed my battery up in the frozen north. Had my fuel freeze up earlier this year on a ski trip. I do not recall the P00AF code being in there though.
If it sounds kind of like crickets chirping then it will most likely be your front brake pad clips. My truck had the same issue and after replacing the pad hardware only (for $8.00 and an hour of my time) the noise went away. You could also try lightly greasing the surface of the clips where...
Agreed in relation to the block heater, as the block heater primarily heats the coolant passage above the oil pan so the oil doesn’t absorb much of the heat until the engine is running and the cooler/heat exchanger in the radiator does its thing. Gotta love a thermally efficient engine!
Seems pretty normal to me. The oil in these trucks warms a bit quicker than its naturally aspirated counterparts. The turbo’s exposure to high temperature exhaust is the main reason for that in my experience.
That being said my trucks oil and coolant are almost always within 5-10°f of each...
Hey all I know this a bit of an older thread but my pinion bearing in the rear diff is starting to make noise and I’m looking to buy an overhaul kit. According to a local Motive Gear distributor they don’t have availability on the kit. However rock auto shows they have it for my truck, Motive...
Check the easiest things first, the battery and its connections. Get the battery load tested, and pull both connections (positive and negative) and clean them/make sure they’re tight. To me this sounds like a bad battery, as these trucks do whacky stuff when the battery gets low. However it...
