Alpha One Gen 2 Drive Shaft

[drewa9]

Does anyone know the difference between the pre 1998 vs 1998 and up Alpha One Gen 2 drive shaft assemblies?

Are they interchangeable?

I have a 2006 Alpha One Gen 2. The pre 1998 shaft are a lot easier to find and a lot cheaper.

Hey @Bondo can you help

Nope,...... I know of no differences, unless the u-joints or something changed,.... but that's only a guess,....
Swapping drive for drive, all the Gen. IIs interchange,......

why would you need to replace that shaft anyway?

At some point I think they went to different u joint bearings using internal clips iirc. I thought it was earlier than that though. @Scott06 was the one that posted the moog cross reference?

I think this is when they changed the input shaft bearing set up from tighten nut to torque to to the rolling torque so would suspect the inout yoke bearings are different.

this is an addition to u joints being different - inside vs outside retaining rings.

as bt dr wrote what’s wrong with it or were you looking for a bolt in if you need unjoints and yoke

The rolling torque change happened with the gen 1's, but the ujoints were the same for all of them. Pretty sure all the gen 2's used the rolling torque.

That may be but the pre 98 and up gen 2 drive use a diff part number for the bearing pack in input yoke than the earlier ones. so hard to say if the earlier driveshaft fits the later or vice versa.
possible it may fit but not sure why not just replace the u joints.

I was just thinking that either way this wouldn't be a straight swap--preload would have to be set up and re-shimmed. Only reason I can think of to just replace the shaft would be if there was a groove in it from the seal. But still easier to speedi-sleeve.

If yoke is grooved yes sleeve it or replace just the yoke
