i know that this is a dodge forum but i've posted this on the jeep forum and no help so here go's. i also have a 08 liberty 4x4 with 36,000, there's a popping sound coming from the front drivers side wheel sometimes when i turn. i think there must be a bolt loose somewhere but everything seams tight. any suggestion? thanks.

 

This same exact thing happened in my last 4x4 whenever I would turn realllllly sharply. I never found out what it was, though, and I just recently got rid of the truck for a new one. Sorry I am useless, but I wanted you to know that you were not alone in this problem! lol

 

had the same problem with a durango i had and it turned out the tirod was loose, but i checked that and it's fine.

 

Have you looked up TSB's for the vehicle? May be something there.

 

When I first got my truck it did that and there was a frame to body screw missing and the body would bounce off the frame causing a popping sound! Dodge fixed it for free

 

Jack up the front and check the ball joints/tierods.....does the sound happen over bumps too?

 

it only happens sometimes when i turn regardless if there's a bump or not
