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.) |

Run the 12.9 bolts instead of the stock ones. Use new Schoor washers every time for a better bite. 4 bolts per CV= 16 total. If you torque them properly no safety wire need.

Done correctly, you won't have any issues with them backing out. |

I wrote it on my 3/8 torque wrench box so I wouldn't have to look it up every time. Did the same for the lug nuts on my 1/2" TW box. (IMG:style_emoticons/default/beerchug.gif) |
