Noise when backing up and turning

This has happened twice since I have had my truck. I am backing up going down my drive way. Nothing special about it just average drive way. So once in cleared the drive way I turn the wheel and hear a ping and then the traction light comes on for just a second and goes off . More of a blink. Then once I go forward its back to normal. All is good again. This has happened once going left and once right. Can't take to dealer cause its happen twice since 2016. Anyone else ever had this issue?

 

does this happen when still rolling backward and shifting into forward ?

 

You've kept count of 2 over 2 years, and know which side it came from?

Thank you.

When I show this to my wife, maybe she won't call me 'retentive' for a couple of days.

In the meantime, I'd not be fretting over your issue. It could be any of a dozen things, and until it's consistent, almost impossible to find.

 

Being a an auto mechanic for over 21 years you get this way lol

 

When I start to slowly turn the wheel is when it happens. Happens so rare hard to pin point anything.

 

Rereading the op , I wonder if the ping could be a sticking brake shoe or pad when it breaks free, thus causing the traction light because of one wheel sticking for a split sec.
Edited!

 

Could be just about anything. When I have time gonna crawl down there and see if anything is out of the ordinary

 

Maybe your 4x4 axles stick momentarily.

 

Anything right now is a possibility.
