What year, type vehicle, and how many miles.

Check the u-joints on the drive shaft.

Lot's of grease, can never have too much, and get under the truck and spray the hell out of it with white lithium grease. Worked wonders for me and acts as a rust inhibitor. Let us know how you make out.

upper ball joints are hard to reach and are often missed by garage at lube time. My squeak goes away after i add grease to both.

A redundant reply but LOTS OF GREASE. I had a squeak and greased the crap out of my front end and now all is good.
