My 03 ES300 has been an excellent car since I bought it as the second owner in 2006--it has 168,000 miles on the clock. Recently the ride has gradually become rougher when I drive over cracks and bumps, although overall handling and quietness remain unchanged. The tires are fairly new Michelin Primacies in good condition. There is no fluid leakage or suspension sag. My question is, What is the immediate cause likely to be? Struts/shocks, rubber mountings, bushings, or other components I'm unaware of? I'm hoping to economize and repair only what's necessary, although I realize that this may not be possible. At present, I'm not sure I will be keeping the car for years into the future. Thanks for your help!
