2016/2017 Howling noise rear end???????

OK guys, I finally listened after dealing with that irritating noise for the last 16k!! I left the service guys at Yota dealership put in plug for hole for lower A frame or code BD1601 T159 T2 99 for those that may want to have dealer try this! Man after all that freaking irritating howling, whistling noise ive been hearing on my new 2017 37K Truck, i can honestly say that this .30 part was the remedy for my problem!!! Man im feeling pretty stupid now for sure!!!

 

The Lower A Arm Plugs are a different sound compared to the Rear Diff Howling, but glad to hear you got rid of some noise in your truck.

 

Man i thought it would be also but the rear end howling noise went completely away with those plugs installed!

 

I actually bought those plugs beforehand just in case they are not already installed in mine. Was worth spending a few bucks versus going thru service trying to get a TSB.

 

What plugs did you use?

Mine were plugged from the Factory
