I'm trying to figure out if I have an OEM or an aftermarket axle in my car. Hopefully someone can help me out. I have a 2001 V70 T5 with a manual and 173,000 miles. The passenger side axle seems to be causing a vibration on the highway. These axles are hard to come by other than as a dealer reman or an Asian made new one. The inner boot has a small tear so I pulled the axle out today thinking I would replace the boot for now and found the clamps on the boot were the cheesy tug, fold over and hammer kind so the boot was replaced at some point but more surprising to me was that the inner CV joint was the tripod style, not the Rzeppa style I was expecting. I thought the inner CV joints were all the Rzeppa style on the manual cars. Is this not the case? Do they only use those on the R and AWD cars or has this axle been replaced with a cheaper aftermarket one? Also, the inner joint seemed to have quite a bit of slop in it. It would need to have some so that the tripod bearings can move in and out but I'm not sure how much is acceptable. Not too sure what to do at this point. I don't like the idea of spending $550 on a reman through the dealer but my only other option seems to be one of the new ones from Asia. They go for as little as $70 but from all reports it seems they are hit and miss on the quality, actually mostly miss. If the axle in the car isn't original, I wonder if it will even be acceptable as a core.
