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) |
