In the mechanic's world there are 2 possible options for u-joints for the 2006 Grand Marquis, the bearing caps could be either 1 1/16" diameter or 1 3/16" diameter, measure your caps diameter before you buy these because this part number is for the 1 1/16" diameter. My vin number + year make and model describes this as the correct part number, but in actuality my u-joints are 1 3/16" diameter and so these are not the correct part for my driveshaft
