Hi all,
With 914 CV joints being NLA now, I recently tried out Beetle CV joints when my old ones wore out on my 914/6 race car. I understand they are made by EMPI. I am using the same 914 axles I've used for years. After about 30 minutes of track time, one of the Beetle joints failed (the inner one on the right side of the car). Basically the joint seems to have been plunging too far inward and the lateral force seems to have just forced the joint apart. No broken parts are immediately apparent. The joint seems to have just fallen apart! I also noted that the inner races of the joints seem to be gouging the output flanges on the trans. This occurred on both sides fo the car. I had noticed some of this wear previously, but it seems to have accelerated significantly with the Beetle joints (especially considering only 30 minutes of use). See the pics below. It's hard to tell from the pics, but the wear spots are basically gouged into the flanges about a millimeter or so deep. I never had any failures or unusual wear with the 914 joints I used for years, so I am at a loss what happened here. Anyone have a similar issue with Beetle joints? I'm wondering if I should be trying Lobro or other joints, or a different setup entirely ... Attached image(s) |

Thanks Bob. It was great to see Nadine after all these years. Hopefully I'll get to see the two of you and one of the teeners at the track sometime soon.
It was sort of a bad kharma weekend for me at the club race. Silly things going wrong all weekend, and then I spun a rod bearing ... I think I'll focus on my 911 for now and worry about the engine over the winter, and get the 914 ready for next year. The 914 has a 2.7L engine putting out something like 250 hp. Since the original 914 CVs held up for so long, I'm going to see how the Lobro Beetle CVs do. Any more hp, and I'd want to upgrade for sure to something like what you have. Scott |
