Drivers of 2004-07 TSX models may come into your store complaining of a vibration in the steering column when the brakes are applied. Acura attributes the condition to excess thickness variation in the front rotors. Cutting or replacing the rotors and installing new-design brake pads, part no. 45022-SEC-A00, which are gentler to the rotor surfaces should eliminate the vibration and prevent further trouble.
Ford says that some 2003 Lincoln Town Cars built before July 1, 2002, may turn on the battery warning light and store trouble code P1246 in computer memory. According to the carmaker, the condition usually occurs when the vehicle is started and placed in drive before allowing the engine to return to idle. Software gremlins in the PCM are the likely cause. Reprogramming the module with updated software is the only surefire fix. Check with a dealer on the specifics of the flash job.
Owners of 2004-06 Pacifica models may complain of a click or pop from the front hub(s) when the transmission is shifted from Drive to Reverse or Reverse to Drive, or while turning and accelerating from a stop. According to Chrysler, insufficient lubrication at the front axle/hub interface is the most likely cause for the noise. Installing a new rubber gasket, part no. 04809863AB, between the outer CV joint and hub bearing should eliminate the condition in short order.
