Truck started making a nasty sound..

[downforce137]

I was driving about 50mph on a paved road, and it started sounding like I was driving on rumble strips on the shoulder.. I shifted into 4HI and it immediately went away. when I shifted back to 2wd, it came and went.. thoughts?

Vacuum leak for the iwes?

Mine did the same thing, same noise, pulled off the road to see what the hell I was dragging, put it into 4H then back to 2H sound went away, it was the left IWE, replaced that one twice, right side still is original.

mines a 2012 with 82K

Im guessing its the IWE on the right front. It was squealing on and off recently. I drove it all over last night and the noise didnt come back again after driving about 4 miles in 4hi.

its just the noise was such a deep vibrational noise I thought the wheel bearing was gone or something but went away within seconds of turning the knob to 4hi

2012, 76 k here, I would rather have locking hubs, rarely malfunctions and easy to repair.

Thanks for info, I am way behind y'all in miles, but gonna listen up. I agree with you very much, manual locking hubs, I miss um.

one of my wheel bearings failed where the CV axle end rides and tore up the bearings running surface on the axle. I'd sure like to put a new end on my CV axle, rather than replacing the whole shaft.

It was pretty full of dirt and mud inside the hub/iwe area, and I feel this could have easily been prevented by maintenance. Started making a noise like I was driving on rumble strips the other day, and I assumed the IWE failed. Got it apart last night and the small bearing inside the wheel hub had come apart, needle bearings everywhere and galled up the axle shaft. I ordered a new wheel hub, and I'll get the numbers off the inner bearings before I put it back together.
