How to remove driveshaft from Porsche

[ATM]

Hello

I need to remove the driveshaft from this Porsche hub. It had a big 36mm nut on which I have removed with a big power bar. I've tried whacking it with a hammer but no joy. The suspension just absorbs the impact as it is attached to a car. I've tried my friends drive shaft tool which didn't fit - see pic below - the centre wasn't big enough for my centre and the nut holes not big enough for my nut spacing. Can I just get a bigger tool or is there a smarter way. Any ideas please let me know.

Thanks

Looks like you need a bigger diameter puller.

Is that what it's called - I didn't know.

[GreenV8S]

If it's that tight, you probably want to refit one of the wheel screws loosely to make sure the disc doesn't fly off when it eventually comes free.

I have a hydraulic type puller that would probably do that, in the absence of that I would remove the disc, apply heat to the hub, put the nut back on to protect the thread & give it a whack.

Deffo this....

Having it pull with only 1 wheel bolt screwed in is making it pull off centre for starters ,never a good thing.

No

The image is just to show the size difference. No pulling was performed.

I found this one on eBay which says hydraulic. Will this do the job?

I don't have a compressor - not sure if relevant - I'm confused how it is hydraulic.

It looks expensive at 55 quid too. Am I getting ripped off?

Hydraulic means liquid not air, it's filled with oil like a trolley jack.
£55 is not expensive for a tool, if it is to you then take to a mechanic who will already have the correct tool.
It's also Chinese, if it snaps in half, then you've been ripped off.
If there are any small engineering shops nearby then a simple tool could be made from a piece of 8mm flat plate with some holes drilled in it which (dependent on relative heights and length of wheel nuts) could do the job.
Alternatively the usual applies 'Take it to someone who knows what they're doing' before you wreck something.

Once set up on the thing you are pulling you turn the T handle on top of the cylinder.
Magnifies the force.

It might be a silly question, but.


Have you undone a ball joint, or split the suspension anywhere to allow the driveshaft to go somewhere?

Before buying a puller, which is very rarely needed to remove a driveshaft, put some penetrating oil around the driveshaft hub joint and allow it an hour, then put the nut back on the shaft (backwards if it is castellated) until it is flush to the end of the shaft. Then use a lump hammer and give 2 or 3 hard strikes.

If you do all the above and cant get any movement, then you need to be sure there is nothing stopping it moving before resulting to a puller.

I cant remember the last time I have had to use a puller to remove 1. It does happen I know, but not often

It's probably got some mild corrosion or more likely liquid 'Bearing fit' in the splines.

So this is a replacement part you've already fitted ?

So does it actually need to come apart ?

A press/puller type tool will be best. The other is holding a suitable punch with an appropriate tool...and a big F Off hammer to hammer the centre of the shaft.

Dont hammer the end of the shaft even with a nut on, or it will damage the threads which will be awkward if you want to keep using that part.

It is a replacement part which I fitted but it was already fitted to the hub which I also fitted. So I fitted them whole hub and all suspension parts and drive shaft in one hit. But the drive shaft is 2 or 3 inches too long as it is from a manual. The point is I did not have the drive shaft separate when I fit the parts. So to my knowledge it was inserted into the hub at the factory.

[stevieturbo]

If you dont have a puller then and dont care about damaging it...whack the F out of it with a hammer then.

Or can you just remove the shaft out of the CV joint and fit a shaft into it of the correct length without disturbing the CV stub ?

Or if press/hammer still struggle it may need heat or some lube etc.

Interesting

Can I split the joint with it in situ?

How would I do that?

[Coilspring]

I wouldn't even attempt to split the joint from the shaft in situ, especially looking at the state of the gearbox end.

If that shaft is scrap, then secure the hub, in vice or against something secure, put the nut on it til it covers the theads, to spread the load, and beat it out.

It is only corrosion (most likely looking at the state of it), or stud lock type glue. Only need to break that seal and it will move.

Be careful you don't distort the shaft by bashing it so badly that it won't fit back through the hole it came through originally.

Have you been outside my house?

What are you looking at which shows the state of the gearbox end?
