Already did a set of struts up front trying to eliminate a knocking sound when hitting moderate bumps. As well as the thermostat and temp sensor and rad. fans when they crapped out day 2. Thank you in advance for any advise.
All automatic R/T's come with MDS. It can be turned off via tuning. You have an 05 with well over 100k miles. Previous owner probably sold it hoping to avoid higher mileage woes lol. Two most common culprits are tension struts and ball joints. You didn't say if you meant tension struts or the spring/shock combo. Considering some of the substandard material that went into our front ends early on, good chance a front end rebuild is in your future. A cooler thermostat is a good idea on these first gen LX cars because all it takes one good serious overheat and you increase the likelihood of a valve seat dropping; caveat though, no point in installing a cooler stat until you have the means to lower the setting on the cooling fans.
