Fnord09 Posted April 28, 2012 Share Posted April 28, 2012 I took my truck to get its u-joints replaced as a rotational squeak developed. First the shop called me and told me I needed a new driveshaft because "they must have used really soft aluminum and the yoke got bent pressing out the old u-joint." As I needed my truck I okayed the work and then complained about having to pay (on a cc) for the shop's screwup. Then the owner tells me that no, the yoke wasn't bent, but that Ford didn't sell u-joints for my driveshaft, and the engineering # for the driveshaft was listed by Ford as 'no serviceable parts available." We went around and around with this until I went to a dealership myself and asked for the printout showing the part # for the u-joints for my truck, and gave it to the shop owner. He bought them and I went in and saw for myself that the parts Ford says should fit don't. The owner said if I could find u-joints that fit he'd refund the money for the new shaft, and measured the dimensions. Within a few minutes of searching I was able to find that they were Dana/Spicer 1310 series u-joints. Why, however, is Ford selling the wrong ones? In fact, I looked at Summit Racing and they recommended the 1330 series, which are .400" wider than the 1310s that actually fit. In any event, if anyone else comes across this problem, on some 2002 4x4 4.0L Supercab Rangers, the u-joints that Ford and other vendors say are correct are not, and the dimensions of the existing u-joints should be measured to find the correct replacements. The Ford part # on the old driveshaft that caused the issue was 1L54-4602-JC. The correct u-joint dimensions are Spicer 1310 series, 3.219" between the outside snaprings, and a 1.062" bearing cap diameter (both ways, both ends of the driveshaft). The replacement driveshaft # is 6L52-4602-E. Quote Link to comment Share on other sites More sharing options...

YT90SC Posted May 11, 2012 Share Posted May 11, 2012 There was more than one driveshaft for that truck, and it may have had a steel one from the factory. The fix for a lot of 'driveshaft bump' issues was replacement with the aluminum unit. OR because the catalogging for a 10 year old truck is somewhat cloudy they may have just gotten the wrong one.

theoldwizard Posted May 11, 2012 Share Posted May 11, 2012 Some old import trucks had the same issue ("no serviceable parts"). Some driveshaft places would cut off the old yoke, weld on a new one and balance it. Quote Link to comment Share on other sites More sharing options...
