I have a '96 2500 4x4 with 104,000 miles. I just refilled the front diff due to a leak, although that probably has nothing with my newest noise. I am getting a "squeaking" noise from the front end when turning. It sounds like it's at wheel speed, so I'm looking at anything that turns. I'm getting ready for a "turn and burn" trip between 600 and 700 miles tomorrow. The truck drives fine, but the noise causes me some concern. Any ideas?

 

front axle end u joint, grease er up and go

 

Trip ended up being around 750 miles. No issues with the truck except that the mileage was not as high as I expected. I averaged almost 20mpg.

 

not bad mpg for winter blend diesel
