986 driveshaft spline hopelessly stuck

Hi all,

First time poster, I've had my 1998 Boxster 986 for about 4 months and I've loved every minute of it up to now.

I noticed a few weeks ago that I had a torn outer CV boot, so I've set about replacing it while also replacing the rear shocks.

I've finally managed to disconnect enough suspension and exhaust bits that the driveshaft has room to drop down and be pulled out. The problem I've got now is that the spline very much doesn't want to be pulled out.

I've tried spraying penetrating oil around the teeth, I've also tried hitting the end of the shaft with a mallet about as hard as I can without knocking the car off the stands.

Does anyone have any good tips/techniques for getting the stuck driveshaft spline out of the hub?

Thanks in advance.

I haven't tried it on my 986 yet, but I imagine it's not much different than other cars.

If you have a compressor, I've had good luck with a Harbor Frieght air hammer and pointed bit right into center hole of the axle.

I hope you didn't flare the end of the axle when you beat on it with a mallet. If so, you may want to grind it down, before you try to push it back.

Here's an extreme case, but I doubt yours is this bad.

Good luck!

Thanks very much for the suggestions.

Hadn't thought of using an air hammer. I don't have one but I have a compressor, could easily pick one up and give it a go.

Using a puller seems like a decent approach too. Was hoping to not have to take the brake caliper off, but I think the pads need replacing anyway so could do that while I'm here.

Will try one of these and post results.

I used a 3 jaw puller with the legs on the hub and the nose on the axle and pushed it out that way, the two times I've had my axles off. Got it as a loaner tool from O'Reilly auto parts.

Just watched the 996 episode of Wheeler Dealers and Ant used a brass drift and a hammer to knock it out.

if its just the boot, then you can handle that without pulling the whole axle out.

Just remove the inner CV joint, slide both boots off, clean best you can, add grease, new boots, and you're off.

I've been using a puller plate from a slide hammer with the center bolt from a normal 3/2 arm puller I bought a kit from OTC years ago.



This has worked really well for me. The other tool is what I use to pop the links out of the suspension. But you can bolt the puller plate with 3 of the wheel bolts to the hub.

I ended up using this giant 3 jaw puller. It quite easily did the job.
I had to stop the hub from turning by attaching a set of multi grips to the puller, but once I did that and tightened it up the spline came straight out.



Reason for it being so stuck was a bit of rust. What do you guys recommend I use for cleaning up the parts and getting the rust off? And what type of grease should I apply to the shaft before I put it back in?

Thanks in advance.

Clean up the rust with a combination of wire brushes and sandpaper . A wire brush chucked into a drill motor will speed things up . I would lightly coat with anti-seize and install .

Congrats on getting it out! You can use a wire brush on the splines to clean out the rust and then put on some Permatex anti-seize.

I've removed well over 100 axles. I hit the socket used to loosen the nut with. Back the nut off a little bit and one or two good hits from a big hammer usually knocks it loose. The early boxsters came with a flared nut but later ones came with a nut/attached washer. The washer will become detached using this method but can be reattached with a quick strike of a hammer or pressed together in a vice.

Great, thanks guys.

That Permatex anti-seize certainly looks like it'll do the job. It's cheap and easy to find too, even better.

Service Manual says to replace the axle nut everytime. I replace mine every other time with no problems, and that's in rust free So,CA.

+1 And they aren't expensive. I use sylglide (napa silicone grease) which doesn't wash away or break down. I live in rust free So AZ. We are so freaking spoiled by our rust free vehicles!
