Luckily I was one block from my apartment, but it still sucked having to hold the flashlight with my knees while I put the drive shaft back on. Check your torque to make sure it is correct. I have been meaning to do this for a few days, and it bit me in the ass. Dont let it happen to you (IMG:style_emoticons/default/slap.gif)

I actually picked up a 8mm Allen socket to allow me to properly torque my CV bolts. I recently put in a set of CV gaskets because for some reason the previous owner did not have any. I need to make my way up to HPH and get the proper wave washers before the autocross this weekend...

QUOTE(SirAndy @ Jul 12 2004, 10:17 PM) Ayup. Me too. Hit me Thursday on the way home from work. Lucky me it was an outboard joint so it didn't flip the axle around like a gian fly-cutter. Double lucky me - I was only 50 yards from my driveway. Didn't even break a sweat pushing it home. No carnage. Just cleaned out the joint, got a gasket out of my stash and bolted it all back together Saturday. Gotta start checking them bolts more often. I thought twice per year was enough. Guess not. -Ben M. ps - This is my first breakdown with this car in the 5 years I've had it as a spring/summer/fall daily driver. Not bad. |

Obviously there has been quite a bit of this lately (IMG:style_emoticons/default/ohmy.gif)
I guess I have a question then. Why can't you use lock-tite on these bolts? (IMG:style_emoticons/default/confused24.gif) Wouldn't that solve the problem? |

It happened to me once and hit my transmission and cracked the shiftrod bushing guide right off. It can cause serious damage.

Between being so tight you can't break them loose, stripped heads or backing out on their own, they are a pain in the butt.

Can't really think of a good long-term solution. Like Clay said - you can't get the holes clean enough for locktite to hold. Safety-wireing would be a serious pain but might be worth it. Mike Mueller is a trained A&P mechanic - maybe he'll give us a tutorial on how to properly safety-wire a series of bolts.

I believe we should go with an "Emergency Action Time Compliance Technical Order" World Wide effective, grounding the entire 914 fleet until these matters have been corrected. Saftey first. I found mine loose one time, but it never seperated. I was Lucky. Have to run, three 747's calling my name today. I have all the info you would need to saftey bolts. I do it everyday. Almost, somedays these fine Boeing machines actually do not malfunction...lol

Is everybody using the OE "schnorr" lock washers? I think they are critical to the assembly.

Never left, but not right.... Group: Members Posts: 381 Joined: 26-January 03 From: Long Beach CA Member No.: 197 Region Association: None |
It's not easy to assemble the CV and not get grease on the bolts. Just before putting the CV on the flange, I clean out the threads with brake cleaner and a Q tip, plus a litte spiral brush used for cleaning spray guns. I check the CV for grease that will get into the bolt hole and clear that out.
After I get the CV up there, I Q tip it again to see how much grease oozed over into the bolt holes being careful not to shoot brake clean directly in the hole and filling up the joint. Then, with Locktite, I insert the bolts always using new serated washers cup facing away from the bolt head. 31 lbs. does the trick. Note: You have to have the flat steel piece that covers 2 holes. If I were to safety wire the bolts, I would wire those 2 together. |

I couldn't get the bolts tight enough not to loosen, on my 911SC. Added serrated washers and that did the trick. The interesting thing is that they never loosened until I replaced an axle. They did not have washers as the car came from the factory, so I assume they were locktited. There is considerable discussion about this on the "large beaked bird", as well as photos (and heated discussion) of safety wiring.

WOW..what a nasty feeling when this happens.
My freak'n driver's side CV came off today (IMG:style_emoticons/default/sad.gif). Th dumb ass thing is I just got the CV tool in the mail and put off the task of tighting them up. The shaft fell onto the shift rod and made one hell of a racket and scared the hell out of me. I was going about 45 when it happened (IMG:style_emoticons/default/ohmy.gif) Called the wife and had her bring the new socket out to me, it was still in the PParts shipping box. Once she arrives and I look at the tool..........Son-of-a- BITCH...it's a 1/2" drive. (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) So back in the car to get the 3/8 to 1/2 adapter from the house. Got the car home with only 3 bolts. One of the bolts sheared off (IMG:style_emoticons/default/sad.gif) Looks like I will need to buy a few now. Man I should have listened to you guys when I read this thread the first time (IMG:style_emoticons/default/beer.gif) Cheers Kerry "now in the fallen CV joint" club |

my cv's are safety wired. I realize my car is track only, but the safety wire is easy to snip during maintenance and adds a very measureable level of security. I'll shoot picks of my bolts with the holes in them....I've already taken them off with my engine drop in progress...
just my $0.02. Bill P. |
