I'm stationed at ft wainwright Alaska and just got back from 2 weeks in the field training, while I was gone temps hit as low as 25 below. I left my trucks engine block heater And other winterized peices urged in and left it in 4x4 HI. I got back yesterday and let it run for 30 mins before driving and when I'm in 4x4 HI AND LET OF THE GAS IT MAKES A NOISE THAT SOUNDS LIKE TIRES RBING ON THE BUMPER, any ideas what it could be? It only happens in 4x4 HI

 

rubbing on the bumper* sorry for the misspelled words and caps.

 

Nobody has any ideas? Im going to take it to the dealership on friday. Does it sound like i did something wrong by leaving it in 4 wheel drive while i was gone for 2 weeks?

 

What about ice build up around the wheels or axles.

 

I would think more of the front drive shaft cause that wouldn't turn if your in 2wd

 

ok thanks ill look into it tomorrow, today i realized it only happens right around 20 mphs, idk if that changes anything but im just trying to narrow down wha it could be
