Good Morning, I am the owner of a 2009 Pat w/44,000 miles. I loaned the vehicle to my daughter and see it when it needs work.

I am retired from Chrysler's Jeep / Truck Engineering department, so I'm no stranger to the undersides of a vehicle.

I will be searching today to see everyone's experience with corroded valve stems and clunking in the front end before money is spent.

Thank You

For the front end, the ball joints and tie-rod ends are usual culprits. Many on here had ball joints go in the 40k mile range. I also had a tie-rod go bad in just 19k miles. I don't know who their supplier for these parts are or were, but they were not durable.

For the valve stems, were there metal valve stem caps? There have been a few folks on here that used steel valve stem caps, and they caused galvanic corrosion. Most broke the valve stem trying to remove them which requires break the tire bead to replace the TPMS sensor.

I will confirm the crappy valve stem issue. Accidentally kicked one of mine, and broke it off. From what I understand, the moisture inside the tire causes the aluminum stem to corrode from the inside. It has nothing at all to do with the material of the caps.

I found out (too late) that you can actually just replace the stems on our units. It saves a couple bucks in parts, but you still need to take the tires off to access the TMPS sensors, regardless.
