Removing Outer CV Joints
 

I have removed the gearbox and (obviously) inner CV's.
In trying to remove the outboard side, I'm having trouble getting the joints to separate from what I assume is the stub axle.
The factory manual is no help on this, and I'm wondering if they are connected by more than the allen bolts on the outside?
If not, does anyone have any tips for persuading them loose without blasting?
Thanks

Joe,

Assuming the you have the axle with the inner CV-joint still attached and just dangling mid-air, do you have all four or six Allen bolts (or Polygon-drive bolts) removed? If so ... there is nothing but a gasket and any possible adhesive or sealant that a previous owner or idiot masquerading as a wrench, may have applied to excess, holding the joint to the stub axle! I would suggest gentle pulling at the far end of the dangling axle ... don't jerk, just your weight applied to the end of the axle should be sufficient to break the 'stiction' ... we are not talking about a cosmic mystery force!

If it's a 4 bolt axle then it has 2 dowel pins that may be stuck so use warrens method.

"Polygon drive bolts"-"cosmic mystery force"-you know, us Porsche fanatics have a language all our own. You have to wonder what the casual bypasser thinks at times, don't you? I mean, where else would you find Porsche coffeemakers as both a major topic and an inside joke? Gotta love it.

Not to mention "stiction."

I think we missed the point. I think Joe has successfully removed the CV on the gearbox side. I think he is asking about the wheel end of the CV. And that is the question I am now asking. Six bolts came off and CV is now dangling from the wheel. I tied them out of the way to remove motor and trans. One of the boots is torn, so they must come off. Gentle tugging doesn't do the trick. Can't see anything holding them. I didn't look very closely as I was more interested in getting the motor out.

David and Joe,

If pulling and pushing in the fore and aft directions doesn't work, then I suggest pulling downward with all of your weight on the end of the axle, followed by rotating the axle 90 degrees, repeat, etc. until the axle breaks loose from the stub axle ... those axles are ove 18" long, so your weight is being multiplied!

If none of the previous suggestions work, then, assuming there IS a gasket present ... if you can identify the precise location of the gasket, you may want to try a putty knife, applied with a mallet and not really much force, as the gaskets are not more than 3/8" wide at the widest point! I have never had to resort to this tactic! But, I do suggest that you clean & repack the CV's and use new gaskets when you put them back on!

If Warrens method still doesn't work you could remove the axle nut and pull the stub out where you can work on it easier. Make sure you tighten the nut back up before you drop the car back down or you will destroy the bearing. If you have the later aluminum bananas those outer joints are really buried in there, so removing the stub w/the axle is a big help, assuming you can get the big nut loose.

Thanks to all for the input.
I was able to cut away about 180 degrees of each gasket with a super sharp knife. After that the trapeze act on the end of the axle worked great. Still not sure what the hold-up was. There was no glue or RTV on the gaskets -- totally dry at the mating surface.
Anyway -- thanks again for the help.

Huh-maybe it WAS that "cosmic mystery force" Warren was talking about, after all.

The ancient greeks would have considered it LOVE. The earth loves all its objects (children) and therefore holds them close (gravity) was their interpretation. So, your CV's apparently love your stub axles vigorously.

You see, there really is a logical explanation for these so-called 'mysterious' forces.
