    ’05 Yukon / OEM audio - bluetooth phone volume?

    Never heard of a Yukon with Bluetooth before 09. No Yukon owners manual shows any Bluetooth information until 09. Maybe there’s an aftermarket device in there.

    Lost Oil Pressure

    Boy’s 03 Denali 6.0 lost oil pressure at 235,000 miles. We tried the overfill the crankcase trick and that didn’t work. We found another engine with about 135,000. We resealed it buying all the special little tools and swapped it out. Runs like a top. We’re going to tear the other one down and...

    I’ve had fuel tank pressure sensors go bad on aftermarket replacement pumps. Put one in an 05 Malibu and 3 months later the sensor was misreading.

    ABS RF wheel activation

Wasn’t rust jacked. There’s a turn cv boot so I have to pull the axle. I’ll clean up the tone ring and go...
