I thought I had posted this yesterday but I have not seen a post of it, so here it goes again. I am dropping the prop shaft as I work on various other repairs and up grades. Is there a way I can ascertain the condition of the CV joints? If I can't would a drive shaft repair facility be able to?

My experience with bad TR8 prop shaft CV joints was a neutral throttle vibration. Also if I was to coast with no load. In my opinion you'd be better off getting a new one. If you do suspect bad joints. RimmerBros have new ones for around $160.00 - Pete

I had no problem telling mine was bad the whole car shook, when I took it off there was vey little movement to indicate it was bad. Went and bought a newer style without the CV joints just the u-joints at both ends. Cost more, but ...

Bob K has it right. Get rid of the CV joints and you'll be happy and safe. Looks more difficult than it really is when you get into it.

Nothing wrong with the OE CV joints. Ask yourself how long did original shaft last. Also you have not determined if your current Driveshaft is bad. Compare the cost of U-joint modification to a new shaft. Last but not least, they give a good long warning when going bad and are super easy to change so unless you're sure it's bad now I would just use it until it hints of needing attention. - Pete

Thank you for the information gentlemen. I have not had any problems with the prop Shaft that I am aware of, I just wondered if there was a way to determine the wear of a CV joint. From what I have read here I will just install what I have until I notice some pro0blem. Thanks again.

To answer your original question. When mine went bad, and it was obvious from the in-car vibration, on the bench the shaft could be held with one hand an definite up and down play could be felt at the rear CVJ. It was hard to feel at first because it is difficult to discern between up and down movement and the normal wiggle that the CVJ is designed for. Interesting side note. The joint that went bad was the rear one and at the same time I noticed slight movement of the differential flange. I found the pinion nut that held the flange on literally hand tight. It should be at 120 ft/lb's. - Pete
