hey guys im running a 3rd gen aluminum drive shaft in a 97 WS6. when i first installed the shaft i notice the u joints where to small and had allot of play when i tighten the bolts to the axle. so i just took off the caps that came with it and installed the caps from my factory steel drive shaft and it bolted up. i was having some weird noise/vibration when accelerating from a stop. then it goes away as i pick up more speed. took it to school and my teacher said that its unsafe and to use the proper u joint or the car could flip over. im doing a 800 mile trip tomorrow so please anyone know the proper u joint or at least a part number? i went to the parts store and had no luck. thanks for the help guys.

 

most likely it is a 1310 to 3R conversion joint. the 4th gens take a 3R u joint, the 3rd gen may be a 1310 but im not sure about the 1LE d/s if thats different from a non-1LE.

i THINK 93-97 4th gen 1LEs got 1310 ujoints which might be a carry over from the 3rd gens, but i cant say for sure.

this may be what you need:

thanks a billion. its on it way.

 

i hope it works out for you. im just making an educated guess. they do list the ujoint cap sizing.

 

put it on and it works perfect. no vibration at all.
