Ive searched pages and pages to try and find an existing post. Sorry if this is a re-post. 06 PSD 4dr long box with 71k. Over the last few days, I've noticed a slight squeak when turning left. At first I thought it could be the breaks but they don't squeak or grind when breaking and I replaced them about a year ago and only put maybe 5k on them. I've heard the possibility of being my whelk bearing. Well today I noticed not only does it make noise when turning left, but also going over small bumps. Any ideas?

 

Wheel bearings, axle shaft u-joints, and ball joints could all do it.
