Just wondering if the N/A axles are the same as the turbo axles? I know that the axles changed a bit during the 85.5 update but I know no other details. Thanks

The 85.5 to 88 NA axles are the same as the 86 turbo axles. 82-85 NAs use a different axle than an 86 turbo, the 87 and up turbos are different than an 86 turbo also. I want to say that the other turbo axles will fit, but I'm not positive. The early axles may also bolt up, but like I said above they're all different.

Yeah, I think you're right.
I'm pretty sure all turbo axles will bolt up to an 86, but they have different part #s. My turbo S transaxle uses 86 axles just fine, so at least the bolt pattern/spacing is correct.
I believe the axles themselves aren't interchangable between the early cars and the turbos, but the cv joints may be (and I think they are).

Ahmet's right in that the '87+ axles have stronger CV-joints. The splines are different so they won't fit on the '85.5-86 944/951 axles. However, the transition was in the middle of '87 sometime. So there are some early '87 951s using the early axles. Even though the CV-joint won't interchange, the entire axle assembly will swap between '85.5-86 944/951 and '87+ models.

The PO replaced the 88 turbo S axles with early axles and I broke 2 CV joints last summer. Both times were "high stress" but still shouldn't have failed. I've since stopped accelerating hard across bumpy pavement, it seems wheelhop is a CV joint killer.

My car is an 86 with 86 axles and CV joints. I've had no failures of the axles or CV joints with 375 rwhp. But then, I don't do drag races with Mustangs.

I purchased a new axle assembly from Paragon last year. As I remember, there was an 86 944T and an 87-91 944T selection. Since the units were "new" complete units, I would think they are not interchangeable. Just give Paragon a call and I am sure they will help.
