Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Rear axle and bearing noises. Marquis bought new. Owner's son-in-law noted minor bearing noise in rear when visiting in 2004. Son-in-law received car after death of mother-in-law in 2012, car had 24K miles at that time. Noticed pronounced rear end noise at that time (a whaa-whaa-whaa matching speed changes). Left rear axle and outboard bearing found to be pitted and were replaced by independent repair shop. Research by owner indicates that axles for this, and other similar Mercury and Ford had factory axles installed that had not been properly heat treated. Now, Nov. 2014, at 43.4K miles the right axle is starting to exhibit noise similar, so repair is up-coming. Will examine NHTSA recall 04V328000 as noted here in other comments posted. Also reference Ford/Mercury service bulletin 0355.

I purchased new tires today for this vehicle. Dealer advised having front end alignment checked due to wear patterns on tires. Brought the vehicle to my front end alignment shop and told then that there is "a flat spot when turning the wheel' the technician drove the vehicle and brought it into the shop to inspect the front end prior to doing any alignment work. The technician called the parts dealer and gave the VIN number and was told the availability of the oem and after market parts. After hanging up the technician stated that Ford had previously recalled the 2003 Grand Marquis for the same issue, (lower steering shaft binding), but they couldn't find any open recall for this vehicle. I was quoted $270 for the part not including labor, alignment and tax. I believe this issue should be re-visited if it was originally a recall issue. Other than that I will have to pay the repair bill. And for the record, this is my 4th Mercury Grand Marquis that I own and never in time that I have been the owner, this issue ever surfaced. Thank you.

I own a 2003 Mercury Grand Marquis. My steering shaft is corroded and it is no longer safe to drive. I contacted my local Ford dealer about the issue after realizing there was a recall on the same part but only to find out that the recall was for 2005-2011. But when I go to buy the part. Its listed for years 2003-2011. I would like to know why 2003 was not on the recall?
