gmc k2500 front drive shaft

[jester]

i have a 1997 gmc k2500 6.5td(of course),nv4500 5-speed, extended cab,extended box, steel front drive shaft and it is completely shot. does anyone know the difference between the auto and 5-speed front drive shaft? im not shure the difference in length between a 4l80e and mine. or are they the same and have the same u-joints? oh and my truck is the hd model with the full floater in the rear if that helps.

Let's take this over to the Drivetrain section and see what the experts over there suggest.

Providing you have an 8,600# GVWR (RPO C6P) -

Part Number for front axle with NV-4500 (RPO MW3): 26057963
Part Number for front axle with 4L80-E (RPO MT1): 26057959

I know the 4L80-E is a beast, it's huge, I would definitely say it's longer than the NV-4500. Given that the part numbers are different I'd say the shafts are different. Can you not rebuild it? Here's a breakdown:

no, cant rebuild, its completely pooched, the splines are so sloppy its not salvageable. the guy who i bought the truck from must have never greased it. and it is the 8600 gvwr. im trying to find one out here but its not easy. anyone got any good places to get one from?

http://www.car-part.com/ For a used one or a driveshaft shop could rebuild or make a new one for you.

4L80 takes diff lenght shaft than a manual tranny.
I got a perfect one for sale out a 95 to fit yours.

For future reference, the NV4500 is the same length as a 700R4/4L60/4L60E.

The 4L80E is longer.
