i have a 2002 Jeep WJ 4.7 V8 with 242hd which is the select track transfer case im so pulling hair out trying to find the correct info on which spicier U Joints to replace mine. i have 2 in back drive shaft and one up front then a double cardan before the tranfercase. so front to back i need five total. even two different dealers cant give me the correct info, both gave me different numbers. even auto parts stores are no help. you all know you cant trust them either. NAPA calls for three different ones????? prices from 93.00 to amazon 9.60 +..for one of them.. does anyone know for fact which spicier U Joints and the location that are used in my WJ any help will be greatly helpful to me. i have gone to many web sites and looked at drawings with # 3 yet there is no parts number for them....i even have a service manual no part number from spicier or even dana. i have like 9 pages of 4"x9" of miss information from many sites....HELP
