Need Help... CV/axle question

[89Vette]

Here is the NAPA replacement axle.
This is the part that is "identical" from left to right:

These are the green cups that the bare CV portion of the above axles go into:

The green cups have, on one side, a long shaft (the part that is hard to find/buy) attached to it. On the other side, is a green cup that has the short shaft attached to it (available at stores).
Both of these shafts are located inside the differential.

Hope this helps...

I guess popoplug (ppl) isn't a good a site as photobucket? The pics are gone from these links...Expired or Storage filled up?

No, Pogoplug is great. I took the pics down a while ago.

Note: after months of having the Napa shafts on, I don't recommend them unless your cups are replaced as well.
Bad vibration since day 1.

That's too bad. NAPA said they use A1 Cardone's. I guess EMPI's really are better? I'm guessing the green cup end didn't fit tight or something? Otherwise, it doesn't seem like they'd cause vibration.... Hmmm....

BTW...I thought that picture of the halfshaft was the key to my understanding in that thread. I always think it's unfortunate to kill picture links.

Ok, changing my opinion 180 degrees on the NAPA shafts!

I just installed the HD torsion bars from Indy4x, and also lowered the front by 1 inch.
Lowering plus 2 inches of Diff Drop put the front shafts back to horizontal/stock angles!

I turned the TOD on today (I have an on/off switch). All is fixed! I had no clacking, vibration... nada!

Back in business.

So, lesson learned...
The shafts need to be as horizontal as possible in order for the balls to ride in the cups properly.

Anyone have the clacking issue on stock shafts while lifted?

I kinda wondered....because I found out that NAPA uses A1-Cardone for their stock. While EMPI is touted as better (bigger balls?), I didn't think anyone had discredited the Cardone stuff as viable.

One would certainly hope.....

Been lifted 2-1/2 to 3 inches for the past three or four years with stock shafts and no diff drop. Never had a clacking issue at all.
