:agree: That's how I split mine. Get yourself a copper and hide mallet and you can give things a really good twatting without the worry of too much damage.

And if you can put a bit of pressure on the joint as well, it helps to shock it free - a scissor jack under the threaded part (with a piece of wood to avoid damage to the thread) with just enough weight on the joint to assist it to 'spring' apart a few millimeters when it releases its grip on the taper.

To resurrect another old thread, I am missing the metal cover from the inboard side of the RH drive shaft.

Borrowing Specky's pic:

Circlip one.jpg


Compared to my drive shaft:

P1130292.jpg


How necessary is this bit of metal given that the jack shaft has a sealed bearing? It is not shown in the IPC as a separate part, does anyone have one available from an old shaft?

I have a new jack shaft ready to fit but would rather wait if it is likely to get damaged due to the missing cover.

I've done this job a couple of times recently, and I agree with the following:
Specky wrote:Simple to remove,
jack up
wheel off
wheel centre out
wheel on
lower car
undo/crack hub nut
jack up


However I follow a different path from here:
Specky wrote:undo jack shaft bolts on gearbox
remove coil over
remove raft assy complete with wishbones and hub, leave caliper connected
slide out drive shaft assy
split shaft on work bench
TTFN

I undo the nut securing the anti-roll bar
Remove the bolt that goes through the bottom of the spring/damper fork
Remove the nut on the bottom ball joint and split the taper
Swing the hub out of the way (pushing the CV joint through it)
Push the lower wishbone down so that the driveshaft can come out from between the fork
Knock or lever out the driveshaft from the inside to release it from the circlip
Pull it out
Striking fear into the hearts of duplicate posts everywhere...! :P

Pulling out drive shaft...

Postby Danevansgolf » Mon 29.09.2014, 16:05

Can I just pull out the drivers side drive shaft. Obviously after dismantling the wheel ends first.. Is there anything else what I should look out for??
The inner boot joints have split and need replacing, so is it just a case of pulling out the shaft and fixing a new boot to it?
Any advise is much appreciated. Thanks.

About the shafts: You can wedge or tap it out, it is held in place by a snap ring.
Carefull though, some of the transmission oil will come out the hole you just created ...

I changed my boots without upsetting the inner bits at all....

... if you undo the metal rings which secure the inner boot (large end) - (but they may be held in with cable ties or lock wire) - the outer bit of the CV joint will remain in place on the inner shaft, and the inner bit (3 - pronged 'spider') will slide out of the joint attached to the outer shaft. (or it may be the other way round - but it doesn't matter - it still works)

You can lift the outer shaft away and onto the workbench where it is straightforward to swap the boots!

# obviously you will need to undo the hub retaining nut first - which will need a new part on assembly #

If you haven't already bought your boots, I would heartily recommend these guys - I iknow the listing is for an Elise - but it's the same parts for an elan.

I got 4 boots, 2 hub nuts and change from £20 with next-day delivery :D

Oh, and once it's apart this way, and you can clean the grease off the shaft, you'll realise that the end bits are held on a spline with a circlip - undo that, and you won't have any drama trying to stretch the new boots over the big bits with a cone - it all just slides on!

Yes you can just pull it out as described. The outer joint and shaft should stay attached to the gearbox.

The GKN number is on the gaiter by the large clamp. It is a very common part so you should easily get the correct one. Make sure it is rubber rather than plastic.

You will need more than one little grease sachet - unless you have found the hole early enough the grease inside will be contaminated.

Don't be too concerned the tripod to shaft spline is a loose fit by design.

The bags of grease that came with my boots were more than enough for the job - and I cleaned evey bit of old stuff out of the joints when I built them (and the'ye the correct material - not plastic)

Just answering the question!

The GKN boot is the correct OEM part.

The correct grease fill will be around 140 -160g

Drive shaft replacement

Postby davidcgriffiths » Sun 24.05.2015, 21:52

I am getting some strange notices from the transmission on my S1 Insuspect the near side drive shaft. Can anyone give me some advice on how to confirm which drive shaft is causing the noise . Can these drive shafts be repaired alternately where can I get replacements if required. :( :(
Update 25/05/15 After having a look this morning looks like the problem is a wheel bearing which is a surprise as it was only MOT'd 300 miles ago, but could be worse & a new bearing is far cheaper than a drive shaft

Driveshaft Replacement

Postby KNZ2552 » Tue 26.05.2015, 07:53

Hello,
I too have noise coming from the transmission which have concluded is the near side driveshaft. I have bought a replacement on E Bay which should arrive later this week. is it a difficult job to do and can I replace this myself? if so what is the procedure?
Thanks Ken

Ken,

I'd have thought that the previous posts on this thread would supply you with both the proceedure and a pretty fair resume of ad-hoc issues, I should combine this info with that supplied in the manual and then decide if you have the time, skill and tools to undertake the task, I can't say that I have done it myself but it would appear quite straight forward (as much as anything is on these cars anyway). When you get your new shaft you will have more info judge from.

Make sure you have a back up plan if required - I believe a tow in to the garage costs £50

I did my first one yesterday and followed the procedure above pretty much apart from I left the inner shaft in the box and pulled the tripod out of the cup.

I did need to modify my ball joint splitter to get it in but that was no real issue.
