Thanks for your reply, Sim. Seems like you had much better luck with the TCs.

My old shocks were softer before I changed them at around 70K miles. By softer, rough and uneven roads were damped better but didn't give much support when cornering. The new TCs felt jarring over the same roads. I have not yet changed the front struts because I wanted to observe the TCs first before committing to the additional expense of having the fronts done by a shop (I did the rears). I'm pretty sure the jarring is coming from the back instead of the front because the wagon area seems to echo the vibrations. BTW, it's not a tailgate rattle issue because I've already dismantled the panels yet the jarring sound is still there. I wonder if the Belgian-made Monroe Sensa-Tracs will give a better ride. Anyone here installed them?
