A few questions...How does a CV fail? Is it progressive or instantaneous? Any warning signs? How many miles does a CV typically last before it fails? When it fails, is it catastrophic? Can it cause an accident if you re at highway speeds or underbody damage? Can our 914s run with just one halfshaft...even temporarily?
I understand stock 914/4 CVs are NLA. What is the best recommended solution? Got photos of a blown CV? TIA. (IMG:style_emoticons/default/biggrin.gif) |

I have had two go. It started as a clicking, progressed as a clunking. I would hear it going around a corner, on takeoff, and then when just cruseing around. The first one let go with a BANG, spitting parts all over. Unless you have a posi you are not going anywhere except on the bed of a tow truck. Your HE's will keep it off the ground but it can bang around above and do damage. I guess it could cause an accident if you freaked out and slammed on the brakes. If you repack the grease in your CV's and keep good dust boots on the they will last a long time if you don't they won't. I think that the load they are under will be a determining factor also as to how long they last. Eric Shea was working on a replacement kit. I believe it is ready. Oh and the second one I had going bad I replaced without incident.
