Thanks! I'll buy that after xmas is out of the way.

Is there anything for the press that can hold the hub/knuckle/bearing carrier/cast piece in place? I've used what the press came with which was two bits of metal but difficult to hold the cast piece straight. Whilst attempting to press the driveshaft out I have managed to bend the cast piece so failed completely. I've removed quite a few driveshafts and not struggled like this before.

At least the press is strong if it is able bend the cast piece anyway!

I’ve blown up or bent a number of items that weren’t supported correctly. It’s a mater of getting bits of metal under to support it square to the press. Also so they can’t slip, that can be a bit nasty.
So you need a new bearing housing now?

Sadly yes and this is 5x100 mk3 golf bearing housing. Very unproductive day. The driveshaft removal tool turned up today too but even with my impact gun and 1m long breaker bar it would not shift the driveshaft on the passenger side either (still on the car)

I'm trying to recall what I did; done this job many times on an A4, on my Golf, on an A2 (the splines are loctited) and on an E Class.  Fairly certain I got all of them with a very large copper headed mallet with the exception of the Merc.

The mallet wouldn't touch the Merc so I bought a hydraulic hub puller:  https://www.ebay.co.uk/itm/252431874613?_trkparms=ispr%3D1&hash=item3ac61cba35:g:eMMAAOxy7nNTULhb&amdata=enc%3AAQAGAAAA4Kpi7Cv6mU%2FtgFzXUQF25VS6oefd0a2%2F%2BNeJK600kNfdnUvI1B08xl2Zy%2FmMnHb83wOXrgq%2FyC%2FvPJB1%2Ft7fMlk8bohxohx2NJacNNIoqUM11FyLQde7xnc8t7RR0wdCH4wk8CvPjPNcJhMfYF%2F4v5c8kiFW1t6aj0%2BaCAJb2F2xmTdoSugrKJsQyO4WfmuzLo%2ByZdrDbc4023EG01SVrN9cmQ9HgCkR8CeCGx2NkMzAtzOw%2BGYuFycqHmA1hl1r0Vukg5LX%2Be%2B%2B2fp%2BITtS%2B1sIQ0DXtX6xxfna%2BJJFXFm5%7Ctkp%3ABFBMzvfZ8L1f
It blew the seals so I knew I needed more than 10 Tons.

Got the shafts off the car and tried the 20 Ton press.  I can't recall exactly how I supported it but it would have been well supported and square.  It has an aluminium bearing housing so would easily be damaged. It wasn't playing and things were getting a bit risky with the press and bearing housing.

The mechanical hub puller had reviews that said it worked with a windy gun so that was my last chance.  Held it with a 1m breaker and worked the screw with a 3/4" breaker.  Just at the point I'd got the PPE out expecting the casting to explode the spline made a cracking noise.  After it cracked a couple more times I was able to finish the job with a 3/4 ratchet.



You asked earlier about tricks for supporting workpieces in the press.  Removal of a stubborn inner bearing race.



I think at this stage with yours I'd get them upright in a vice and flood the flange / spline with penetrating oil then I would go and enjoy Christmas. Have a well earned break.

Thanks and very helpful to see it in action. I've also bought a 12t axle press - a little bit like the one from amazon that bolts to the hub but with a hydro screw in. I do at least 2 jobs like this a year so I hope it save me hassle if I come against this again.

Hoping to save the axle and the carrier on the passenger side with it. Drivers side is toast.

Having a day off the cars today. Cheers for your help PWardy have a great Christmas.

@PWardy I bought this bit of kit that makes supporting items easier in the press - well worth it



I ended up buying some carriers but the press easily got the old bearings out.

Even supported properly the driveshafts on the old carriers still won't budge from the hub and have just bent the cast where it was supported even further. If I ever get them out I probably could bend it back - ABS sensnor and carrier bolt holes are where it went. I assume the best way now ould have been to dismantle the CV joint and press out he hub with drive axle still present. 

Would be nice to find a support that is circular and enables the carrier to rest and bearing to pop into the support. I'm still supporting the carrier on weaker areas on my new purchase.

That's a smart bit of kit! I have a 6-tonne bench press rather than the free-standing one. Can't remember what I paid it was a few years back now but wasn't expensive. Like most tools it has paid for itself many times over, you just need to have the space to keep all these things. If I ever press out a bush or bearing I usually keep the old collar as I know it'll come in handy next time.

That's a good tip cheers. It's on the floor somewhere.

This is a 20t press but not really necessary and think a 6 would do what I need. I just went all out as could not get the driveshaft out of the hub.

One bearing did distintegrate on pressing and the outer part of it remained in the carrier. I resorted to carefull cutting it with the dremmel to get it out. This is a mk3 carrier and has a lip on the far end so can't push it out once the inards are gone :(

That looks very useful. Where did you get it from please?

Not cheap ...

What would be really useful is a round pieve of metal just wide enough for the cast piece to sit on but not get in the way of the bearing. That would take some of the strain off of the points supported on the above contraption.

Would an old brake disc be any use?

Yeah blood good idea that! I'll try it out a little later

I saw the support jig and assumed everything had worked out.  Now that the carrier is bent probably only the drive flange is salvageable.  Support flange, an old disc is a good idea then press out CV joint.  Back to the jig then press on back of drive flange only it may come out but likely the bearings will explode.  Retrieve inner and outer races, I posted my set up above.

If all else fails, the whole assembly costs less than £30 new  :o  :o

Unfortunatley it's a 5x100 car - they're £293 each new! 4x100 is better in everyway for cost of ownership :(
