About two years ago, I did a power steering flush with Quantum Blue steering fluid on my 2006 Charger. This past winter, when we had temperatures below freezing for two months in Western New York, I noticed a significant decrease in steering wheel responsiveness. Now that temps are much more 'normal' the steering is still sluggish - most noticeably when making a turn - have to manually return the wheel to center versus the automatic return you would expect. Is it time for another flush of the power steering fluid? I only put about 10,000 miles on this car per year, so since the last flush we can estimate it has been driven about 20,000 miles. The Charger currently has 86,000 miles on it. Thanks for assistance and advice!
