I have had my 07 1500 QC for 2 years. Started getting a front end noise after a few months. Sounds like its from the left side. It's a low thud kind of noise that I get on small bumps, ruts in road, or even in my driveway when the weight shifts as I start moving. I don't really get it on big bumps. The noise is very aggravating. Changed sway-bar links and bushings, tie rods and ball joints. They were bad and needed it, wasn't just tying stuff to fix noise. Here is the crazy part, I only get the Sound during the winter when it's cold. The noise was driving me crazy and it suddenly stopped when it got warm. I though it just may have been a coincidence but when it got cold again this year the sound came back. Now that it is warm again the sound is gone! Any ideas on this one?

 

Grease viscosity too thick, maybe?

 

Bad shock?

 

Would a bad strut make that type of sound? My left strut was leaking so I know it's bad. Tomorrow I'm going over to my buddy's house who's a mechanic. We're going to check out which ones we need and order them up.
