With your front tailshaft that goes to your transfer case to your front diff.when I took it out does the spline suppose to just come out out the shaft

[Deego]

So you just can't slide it back into place.

no. 1.0 have a solid shaft with 8mm bolt holes. 1.3 nt has a hollow shaft with 8mm bolt holes and 1.3 wt has hollow shaft with 10mm bolt holes.

coilys probably have shafts made out of cheese with paper clips to hold it together.

86 and 90 have the same shaft and unis, it's only the flanges that re different.

you cant un bolt a tailshaft from a 1990 sierra and bolt it into a 1986 sierra

[royce]

If you want to replace the shaft cauyse you pulled it apart and now dont know what to do

look closely where the 2 bits slide together, any luck youll see apunch mark on both bits, lines these up and slide it together

[Deego]

I'm looking at a 1986 model and I wAnt the tailshaft to go on my 1990.

[zooky08]

What's wrong with your one?

[Deego]

The spline is real slopping you can wiggles around when you shake the tailshaft
