Ok so picked up 2 new brand new CV shafts from Napa. I was gonna go with the reman'd but when I saw that they came greased, with boots that looked very similar to stocks, I thought what the heck, maybe they will work.

Measured them up back at the house, and the new ones are 30 mm shorter than the one I removed. WTF? And I know my original isn't out, becuase it is within the specs of the FSM (393 - 403 mm I believe, Flange to back of outer CV).

Am I missing something? I don't want to take these back if there is nothing wrong with them, but 30 mm seems like way too much to be out. For the record, both the new ones from napa are the same length.

Has anyone used these new cv shafts with ne success? I think im back to the reman'd ones now. sigh. Oh well, this way it will give me time to weld on a new shock mount to my lower control arm after I couldn't get that bolt out and it got a 'little bit' hammered on.

Maybe they gave you the wrong part? Id call and verify first

Hell, call a different napa in a different city if you want

don't forget there is some compression and extension allowed by the shaft as it travels up and down with the wheel, so compress them fully and compare measurements.

Yes, I thought of this as well, but with the new ones being shorter than the used ones off the truck, I found it hard to believe that they would EXTEND 30 mm beyond their standard position. I could be wrong, but couldn't this damage the cv's with too much pressure pulling outward (ie too short a shaft)??? I was under the impression you shouldn't apply outward pressure to those joints.

The 3-sided metal housing next to the differential is long for a reason. It allows the axle to go short or extend as the A arm travels up and down. As suggested, compress and extend the new axles and see if they match the FSM numbers plus or minus about 6 mm. And, what I have learned from the past, just because the part number is correct doesn't mean some goober put the right part in the box or bag at the factory.
