Kowen117 No light bar. Put wheel bearings on today and drove it 19 miles including about 10 miles on the interstate. So far no noise. I am going to take about a 150 mile trip one way towing the boat this weekend so I will update again after the trip.

William Sheeler Do u have a light bar? I have a light bar and I found that the vibration from the truck while moving caused the aluminum fins of the light bar to vibrate so fast they would make a whine noise

armorer1 I had that same noise a while back. Drove me nuts and it had no effect on anything else. Finally found the source. It was only the cap on the degas bottle failing.....A new cap solved the mystery.

1AAuto.com Hi there! We offer a limited lifetime warranty on Timken wheel bearing/hub assemblies for manufacturer defects--not normal wear-and-tear situations. Let us know if you have any questions!

SparkyF250 If it's a whine after working on it. Don't tell you wife how much you spent, then she won't whine.

jokester00 Check with @1AAuto.com for new Timken wheel bearing/hub assemblies. Most places are only 3yr warranty for Timken, but I think 1AAUTO extends them for a lifetime warranty - at least, they used to!

Kowen117 Yes it is 4x4 tried locking the hubs manually and it still made the noise. Jacked up the front end and the passenger side wheel bearing has quite a bit of play. I thought the noise is coming more from the drivers side but it is hard to tell. I think I’m going to replace both front hub assy and recheck. The passenger one is definitely in need of replacement anyway so no harm in doing them both.

You missed that part, I think

This statement also rules out anything engine related

I assumed, that the truck is 4x4, that is why I mentioned the hub needle bearing - or just dried out grease
locking in manually stops the internal rotation on the axle shaft
A "dry" hub can cause the axle shaft to rotate, and depending if you have the ESOF, the big seal can be worn and may chatter
Yeah, I totally missed that part...my bad.

Has it ever done it sitting idle in park, or just while underway? Next time you get it to start acting up, stop the truck and put in park to see if it will do it then. If so, check the fuel pump..
