so while installing the motor and transmission yesterday- and it seemed to go so smooth, the cv and axle got out of position, the inner must have gotten bumped and twisted , so i was just now trying to get the one that fell out back in , but also noticed they if i spin the axle the outer one is kind of off center as well, so now i am wondering if i am going to have to pull the whole axle to get these put back in the cage and on the axle?? seems like i will have to pull the whole assembly, to get them circlip off and put it all back together properly—-
pandora’s box here - opening a can of worms- i have to put it on the ground to take off the outer axle nut, then pull the shaft right? looks like there is not enough room to pull it with He in and that will have to be pulled too! - can i leave the other side all hooked up? Advice please!! Phil |

I never pull the stud to get the cv shaft out
You can use the parking brake to loosen the 12 points and pull just the axle Sounds like a good too me to disassemble. Wash. Inspect. Repack |

Repack ok, so lock parking break(just installed new cable, should grab good enough, loosen the 4 outer c12pt cv bolts, pull out cv etc? Brant- thanks for the quick reply i would have gone the long way around this for sure!!! Philip |

I would probably try to find a couple phillips screwdrivers or long pin punch or hardened rod that fit snug in the bolt hole of the outer race and see if I could wiggle the race loose.
Good luck Jim |

Probably better at this point to just remove the castle nut and bang the stub axle out.
https://www.youtube.com/watch?v=7a5ACf2xK6Y&t=117s Please forgive the crude quality. I think it was the first 914 video I ever made. A 20Volt battery powered impact wrench will be your friend. And here's a video on how to refurbish the CV joints...made much more recently (IMG:style_emoticons/default/wink.gif) https://www.youtube.com/watch?v=F-5Xpug52Qw&t=277s |

I use a long tire bar
With a slight bend in n the end I always use that to pry sideways and loosen the two roll pins as I pull the outer And with two cars/ one a race car that gets frequent cv service. I’ve never yet had to pull the stub axle |

I’ve never yet had to pull the stub axle we’ll, i can see that, i pulled to jar on the outer, i was prying it h have a long bar just like you are describing, and the inner cage and balls just pulled right out and i think that’s because somehow in putting it up out of the way it got jammed and out of position- sucks- - well at this point i need to move forward- but i am done for tonight, the frustration of what should have been a 1/2 hour job to bold up the two inner CV’s to the trans wound up 3.5 hours of one cv hooked up, the other pulled out falling apart and a mess. i am running out of time- but i have to walk away at this point, - tomorrow i may put the tire on and try and remove the castle nut and push it out. i did get the inner end reassembled back on the shaft .

Probably better at this point to just remove the castle nut and bang the stub axle out. (IMG:style_emoticons/default/agree.gif) But I have access to an impact gun. However, theres is also minimal risk here is that you accidentally separate the rear wheel bearing races if the stub hasn't been out in 50 odd years and is likely to be stuck/corroded to the wheel bearing inner race. If you don't want to risk the wheel bearing, the other method suggested by Brant would be a really close 2nd for me. |

If you don't want to risk the wheel bearing, the other method suggested by Brant would be a really close 2nd for me. i did all new bushings bearings and CV’s 6 years ago, along with the 5 lug conversion, all new bushings , pivot shaft etc etc. so everything including brake calipers and lines were put in new back then. it shouldn’t be rusted into place , but i see what you are saying about the bearing, i’d hate or damage that so hopefully the shat will slide out easily. so pissed i should have had the car running and doing the break in right now. i am telling you i have a freaking big pry bar 2 actually and tried working that back and forth and no feeling at all that those pins were working loose. |

That's some really odd discoloration on that CV. Almost looks like it got really hot?

I think that discoloration is from the heat treating process of the machined bearing surface, I have seen it on other brand new CV joints. Have not looked at a new or old 914 CV for some time.

I use a two foot piece of angle iron that I have drilled two ø 15 mm holes in to be able to bolt it to two wheel studs. Let the free end of the angle iron then be the counterhold against the floor as you unscrew the castle nut. Works every time with or without an impact wrench.
Excuse my terrible paint skills but I think you get the idea. Much easier to do this way than to put a wheel on the ground. |

That would make sense, it's too even for anything that happened during its lifetime. (IMG:style_emoticons/default/idea.gif) |

Phil - If you can see pitting or feel ridges with your fingernail, it's a problem. Discoloration usually isn't an issue.
