anyone know whats the difference and what one i need?

[sgg93]

On some trucks, there are two driveshafts. One coming from the Transmission (or Transfer Case) and one going to the differential. On those, there's a U-joint in the middle. My 94 is a one piece. Hell, I think most of them were. But check.

Kyle if your truck is a single cab 8ft bed it takes two joints

Kyle were on the cape u located? I'm from the south shore

[sgg93]

Mine is reg cab 8ft bed. Single shaft... Now maybe only the 4x4's are single. Never messed with a 2wd.

Well, do you have a 2 or 3 joint shaft? 2 u joints is for a single piece shaft. 3 is for a two.

[Kyle J]

there a u joint at the rear nere the axle and then it has a joint before it goes into the transfer case? that is a 2 peice right? i dident know they even made a 3 peice drive shaft.
