j.vocaty, you will hear some noise while in 4wd, if it excessive and it makes you feel uncomfortable or unsafe, have it checked out, better to be safe than sorry.
Like Shaun said, it's a normal noise noticed it in the F150 too.
Please remember, all, during this snowey season 4 WD does not mean 4 W Stop. It does nothing as most of you know for stopping. It only gives you a little better grip/traction, when driving on snow packed roads.
So please be careful and don't think you can own the road in 4 w d and stay away from those slushy edges of the road. I have now seen 3 vehicles on our road that went too fast for the conditions that have spun out off the road because of this. So be careful where ever you live and and have to drive in snow/ice and slush.
I feel very lucky that after having not driven in snow or icy roads in 10 yrs the experience is still in tact and I've made it to work (having to be at work at midnight and then home the next morning) YEA ME! MY 2 W D does great! Even if it is a white out and can't see 3 ft past the front of my truck.
I did drive Ford guys 4 W D F150 and sure did notice a big difference in handling while driving on the stuff.
xxxxx However, I am still going to keep my fingers crossed for the rest of this winter :lol:
