Well, just recently our Commander (2006 4.7 AWD 62k miles) randomly beganmaking a noise that can only be explained as the same sound a flat tire makes. The tires are fine so we can rule that out. We did have our Commander at the dealer earlier this year for an clunking suspecsion type noise in the front left side when traveling over larger road imperfections. Of course they could not replicate it. We took our verhicle back to the dealer for the "flat tire sound" and they of course can not replicate the sound and have said that everything is tight under there. That was the previous answer/solution they proved for the front clunking. The vehicle is under a Jeep extended warranty that runs out soon. I think they just want us to keep forking over $100 deductable each visit.
