Inner Cv Joint - Non Removable?

[chipstick 382 1 Cars]

I've a pair of 309 shafts to fit but noticed a small nick in the inner boot on the longer drivers side shaft. I ordered up a new boot and this evening cut the old one off and set about seeing what was what.

 

The inner CV joint has no circlip holding it on. It's pressed on and then 3 splines of the shaft have been knocked down to retain it rendering it non removable.

 

 

Excuse the tape bearing belt. I don't fancy needles everywhere there's no circlip on those either!

 

Does this 'trademark' method identify a possible manufacturer? I also noticed no thrust cap or spring in the cup. I see mention that not all shafts contain this.

 

So thos leaves me with a split shaft and a boot I can't unite as easily as I had hoped. I warmed the boot up and tried to slide it down a well lubed slightly conical object to test it's flexibility and I don't think I have a hope in hell of getting it down a cone so I'm unsure whether it's worth me buying one and hoping for the best or just exchanging these used shafts for a pair of AMK's.

 

I did contemplate removing the outer CV and fitting the boot from that end but no doubt I'll face a similar story so I want to weigh up my options.

Had similar issues in Austria with half a 406 drive shaft and half a 205/406 hybrid shaft. In the end, brute force and ignorance prevailed. Oh and a BFH.

That is removable, just mark it then knock it off, make sure it goes back on the same splines.

 

Circlip is a base model thing, wont be found on the larger BE or ML stuff i.m.e.

Thanks. Successfully knocked off

 

I'm hoping there wasn't supposed to be a spring in there rather than a previous boot repair means it was lost on disassembly?

 

Presumably the joint being knocked back on will retain it suitably without the 'tabs' holding it in position.

 

I nearly forgot the mark the splines for refitting just out of curiosity what would happen it it was just put on any old way?

To do it properly you should have knocked the outer joint off the shaft.

 

Then you can just slide the new boot onto the inner joint.

 

Then put outer boot back, and knock outer CV joint on again..

 

No need for cutting in things

To do it properly?

Why go through the ball ache of banging the outer joint off when essentially once you remove the inner boot clips the joint falls off. Also in doing it this way you can leave the inner joint in the gearbox saving the oil. Before I even considered removing the outer joint I'd use a cone to slip it over it.

I personally didn't see the point in disturbing the outer CV boot and removing that to get another boot on for the inner.

[welshpug 1,675]

Indeed, no need to touch the outer whatsoever.

[B1ack_Mi16 67]

Fair enough, but surely you need to grind that staked tab off to get the outer joint to slide off.

 

I always remove the outer joint when doing this, it's a small and quick job.

the inner bearing housing just taps off and back on its a taper fit

So you do twice as much work as needed every time then?!

 

you just knock the Tripod off.

 

its bad enough faffing with the clips on one boot let alone two! v and then there's CV grease!

My exact thoughts previously. Although when gripped in the vice and tapped with a ball joint splitter it came off easily.

 

The issue I had when I put it back on was it was very loose and I fear it could potentially slide off - although when fitted back to the car it shouldn't extend that much, but was still a worry none the less.

 

I'm going to look at getting some replacement shafts this afternoon now as the boot I bought is crap to say the least. The fit is poor and the clips are also as when tightening it just wants to move down the boot.

[welshpug 1,675]

you just buy proper boots surely not another shaft?!

[chipstick 382 1 Cars]

One of the outer joints has some play and this long one very slight play, so I feel I'd be in a better position to get a pair of shafts and fit those and get out and enjoy the car ASAP than to fit them, find they knock and need to come off again down the line.

If you have removed the inner tripod then when you refit it you need to securely stake the shaft to stop it moving. The tripod should move in the inner cv cup, NOT up and down the shaft splines.

All the ones I have ever done (and its quite a lot) have either had the inner joint tripod secured with a circlip, or with the splines "staked" as per the picture near the top of this thread. I have never come across a taper fit on a splined joint.
