Should have checked them myself....but the inner CV bolts looosened up and I munched the roll pins and the inner flange......I got home by hand tightening the bolts and driving home slowly.
Next time they will be safety wired.... (IMG:style_emoticons/default/wacko.gif) Moral of the story....allways put the car on the rack and check DAPO stuff like this..... |

Ya mine loosen up during the first 150 miles. Luckily I discovered it before the WCC AX. Safety wire is on the list for this falls tear down.

The same thing happen to me with the addition of the front lug nuts (were also hand tight)
Only had to drive it home from where I agreed to meet the transporter about 2 miles I noticed the noise about 1/2 way home. Got out to check had only 3 on each side(Front!!) Hand tight. Carefully drove it home. I Noticed the cv bolts during the engine drop whats next ? I will now replace, check, and tight untill I am comfortable with driving it or (IMG:style_emoticons/default/sawzall-smiley.gif) just kidding. |

Clay Perrine has also suggested going to a capscrew (bolt...) long enough that you can add a washer and half-height jam nut on the back of the CV (especially for the outboard end that you can't loosen in the car anyway ...). i think i'll stay with the wire but it's an interesting alternative... |

Do you twist the safety wire by hand, or do you have a tool to do that? I vaguely remember seeing a cool tool that twisted the pair of wires together nicely. -Rusty (IMG:style_emoticons/default/smoke.gif) |

QUOTE(Lawrence @ Jul 4 2004, 08:47 PM) Do you twist the safety wire by hand, or do you have a tool to do that? standard safety-wire pliers. they come in at least two sizes; i have the full-size pliers but there are places where the shorter ones would be a help (access issues...) they're not expensive, and all the race places (Summit, Pegasus, RacerPartsWholesale.com ....) have them. the pliers have a spring-loaded clip to keep them closed, and a spiral rod you pull to make them twirl around. they're supposed to have a spring return on that spiral but mine broke years ago. they're about $30/ i've been having a hard time finding wire, actually, there is a proper very soft stainless steel wire for this purpose, and i did finally get a spool at Summit. for our purposes, the 0.032" is a good all-around size but 0.025" is nice to have for light applications. Carrol Smith's "Prepare To Win" shows most of the standard twisting patterns and techniques, and IIRC there's a pamphlet with the tool too. i'll get a photograph of my axle flanges when i get a chance ... for this application, i like to wire paired bolts. run the wire so that it tends to tighten both bolts. it takes some practive to know how far away from the first fastener to grab the wires so that when it's twisted, it winds up exactly at the second fastener. i figure about a third of the distance is reduced by the twist.

Anyway, we always had them in my Avionics shop, so it comes in one of the tool kits. (IMG:style_emoticons/default/smile.gif) -Dan |

It all happens so fast! Group: Members Posts: 4,893 Joined: 5-November 03 From: minnetonka, mn Member No.: 1,315 Region Association: Upper MidWest |
I had a CV bolts come off on me last year, it was the first time it ever happened to me in 30 years of teener ownership, I always had heard they could loosen up but I had to experience it to believe it, The bolts were the allen head style so I went back to the stock splined bolts.
I was lucky when mine let go I was starting out in 1st making a right hand turn, Scared the shit out of me when the cv smashed the shift rod and the shift lever jumped out of my hand. Only minutes before I had the car up to a hundred on the highway. I plan on wiring them also for now I painted red slashes on them so I can see if they loosen. I also used red loctite while fastening them. |
