I need to replace the left rear stub axle on my 70 bus because it stripped, do I just remove the axle and hammer the stub axle out? thanks for any help. |

Yep, remove the nut, pull the drum off, the cv/axle and the stub will come out with a little hammer work. Don't forget to grease the bearings while you have the stub out. Use a peice of wood to protect the flange from hammer blows when you put the replacement stub axle in. |

Zombie thread, I know....
Sounds easy enough to remove the stub. How about to re-install it? Does it slip right back in, does everything in the bearing hub have to be taken apart, or.... what would the process be?
I may be replacing the current stub (early) with a late/shorter stub
Thanks in advance |

For which reason(s) (other than the obvious too short for the drum/castle nut)?
I'm also replacing drums for discs by way of late wheel hub.
That looks like a great article. I just skimmed through it but will give it a good read tonight. Thanks. |

Good article. Very thorough.
The article is under the assumption that I'm replacing bearings, so obviously it shows a complete teardown.
My question is: can I re-install the stub without disassembling everything in the bearing housing (bearings, seals, etc)? ...Anyone? |

Yes. But! It's only a short put to get fresh grease into the bearings and pop in new seals. This can also be done without removing the bearings if need be. you'll be miles ahead if you do! |

What late wheel hub lets you use discs with a stock stub axle? Yes the early/late axles are about an inch different in size. Yes you can gently tap the old stub axle out and gently tap the new one in. But why would you stop there? AT LEAST take a needle style grease gun and shoot some grease into the bearings. Cup a handful of extra CV grease into the new stub axle end or into the CV joint itself to replace the lost grease from the old stub axle. I personally repack my bearings every 30k miles, and other than that I never remove my drums or stub axles. If I had to take the axle out, it's only an hours extra work to get 30k miles of maintnence out of the way instead of redoing all the work later. _________________ Learn how your vintage VW works.

If I had the axle out I would not dream of not replacing the seals. As others have said adding a bit of extra grease isn't a bad idea either. |

Thanks. All great input.
I'm not opposed to replacing the seals and repacking the bearings. I asked the question to see what was the simplest way to install the stub only, because I'm ignorant about mechanics, but I'm handy. However, I'm afraid of screwing something up beyond repair or being stranded not knowing how things go back together.
The seals and repacking does look simple enough though, and that article is very helpful. Will probably give it a shot.

Old Speed makes an early bay disc/porsche pattern kit that uses stock late bay stub (hence me needing to replace it) and stock late bay wheel hub. Hub is redrilled/studded to 5x130, and slightly trimmed for the Porsche disc to slip over
I would imagine that if you wanted to run it on a late bay you could just redrill the disc instead? |

I got my rear housings apart, cleaned and repacked. When I removed the old/stock stub axles, as expected, they came out with some resistance. A bunch of solid taps and off they came. When I reinstalled them with the late stub axles, the driver side went in, again, with expected resistance... a million little taps and in she went. BUT the driver side almost slid right in, I just held on to the housing, put some pressure on it with my thumbs and she went all the way in... that's not right, right? Is there a -big- chance the inner races will spin on the stub axle, or would they hold once the axle nut is torqued down? |

The inner races are clamped together and to the stub axle by the enormous force from the axle nut, making a solid stack. They will not
slip on the axle. The article by Amskeptic in the link given above illustrates that nicely with colorized drawings. _________________ '67 bug: seized by the authorities
