2015 SR5 (4.0) 4x4 cross post

Recently had a bit o' weirdness with my truck. Check engine light and Trac Off lights came on simultaneously with a trouble code of A2441. The A2441 comes back as a bolt on the intake just needs tightening, but, I'm wondering about why the Trac Off light came on too? Anyone experience this?

Also, separately, I have had a constant rhythmic "wumm, wumm" sound and vibration coming from the front during operation. It happens whether I'm in 2x4 or 4x4. I noticed a torn CV boot on the drivers side CV Axle and replaced it. Sound and vib still occur. I'm really hoping it's not the front diff. Any clues on this as well would be greatly appreciated. I hope everyone has an awesome day.

 

Sounds like you may have a problem with a wheel bearing and ABS sensor reading

jack it up and play with the wheels, but you will get noise before movement usually

how many miles?

 

118k miles

 

Trac light comes on any time the MIL illuminates, standard Toyota check engine response.
