Was going to take the 914 out for a spin tonight (IMG:style_emoticons/default/driving.gif) and two streets from the house *POP* and engine free revs... Figured I broke an axle or something along those lines and sure enough drive side axle is no longer connected to the trans. Haven't dug in to find out if the bolts sheared or backed out but it needs fixing.
I'm planning on replacing all the CV bolts with the safety wire versions from 914 rubber and obviously safety wiring them. But should I locktite them? Antisieze? Neither? Figure I'd clean them and repack the grease, anything else while I'm under there? Might finally put the new shifter bushings I've had sitting around for eons... (Also how many are there? I think VW has 6 bolts per CV, same for our little NARP? *EDIT* 914 rubber says it right on their site, 16 total.) |

I think it’s a good idea to recheck the torque after 500-ish miles as the gaskets can settle a bit. After the retorque I’ve never had one loosen and I don’t use safety wire.

QUOTE(michael7810 @ Jul 3 2020, 01:36 PM)  I think it’s a good idea to recheck the torque after 500-ish miles as the gaskets can settle a bit. After the retorque I’ve never had one loosen and I don’t use safety wire. The question comes up all the time on Pelican. Porsche doesn't safety wire the cv bolts on their passenger cars. The answer is to follow the correct procedure for install and they will stay tight. |
