I bought my 2010 Nitro the other day and noticed a noise coming from the front of the vehicle. Whenever I slowly go over a speed bump or any bump, I hear a creaking coming from the front end. Sounds like a old rusty spring, or a joint that has not lubrication. When I test drove it, it did not make the noise but I also did not go over any speed bumps or bumps for that matter. Looking for any opinions since I can take it back to the dealer to have him look it at if it is something serious. If it helps, when I test drove it, there was alot of precipitation and it was around 50 degrees, night time. Recently, its been very dry and down to about 30 degrees, day time when I first noticed it. Now its roughly 9 degrees with some precipitation. Sorry if that is irrelevant but coming from an SRT-4, every little detail counts!
