I have an '04 2500 Silverado. When making a slow turn to the right there is a loud groan coming from the left front suspension. Any ideas what this might be? Truck drives OK.

 

Hub bearing?

 

good chance its a wheel bearing/hub assembly jack the front up and grab the tire at 12 and 6 o clock and see if you can rock it

 

cleavland ir right jack up truck and shake the tire you shouldnt get but 1/2 in play and more then that find whats lose cvjoint hub shock tierod there's a few things can have this affect and sound travels too so look on both sides

 

Bingo, we have a winner!

 

One thing if you have replaced tires lately especially with larger tires you might check that the left front tire is not rubbing on the inner fender well.. Just a thought as it happened to my 2500HD
