Hi,
We've all been there right :) I'm struggling with 3 nuts that used to hold the stone guard on the rear of the front discs. What methods are tried and tested on getting these out?
So far I have tried
Welding a nut to the top (didn't work but maybe because my nuts are coated though)
Cut slots in them
Banging a smaller socket ontop (crumbled)
Loads of wd40

What other methods do you do? Wasted a good 2 hours now :D
You could try drilling through the bolt very risky unless you drill square and central. If you drill slightly undersize and then run a tap through to clean the threads.

I hate doing the drilling. Did it once and ended up on the pish and lost the thread too... is there a proper method? Undersized drill bit and increased diameter?
Have to say its very hard to get right. The only other way would b to remove the carrier and take it to an engineering firm and see if they can do it maybe by spark erosion. Probably cost less to replace the whole lot.

If it's that stuck I expect it will snap before coming lose.
Drilling from the other side maybe easier. Centre punch and the small drill bit going up a size until and the clear threads with a tap.
Thanks guys, I think having had a few wines this evening I've concluded those bloody hubs need to come off the car so they can be worked on the bench instead. I will try the drilling and will do as you say and go from behind - I just have to make sure I don't go a bigger diameter than the bolt otherwise rather than tapping I'll have to helicoil which will be more kit I have to buy!
This hub is actually the mk3 16v which is 5x100. I've seen on ebay tonight you can buy complete hubs with new bearings pressed in for 4x100 for £138 https://www.ebay.co.uk/itm/164399409948?fits=Model%3AGolf&hash=item2646f7eb1c%3Ag%3Aj6kAAOSwAS1ff4aU.
Since I want to change my bearings as well that would be a great option but not available on the 5x100. Might be useful for others reading though.
Irwin bolt removal tool. I bought a set when it got my previous mk2 and it’s got me out of a fix on many vehicles since. It’s my go to.
Heat and mole-grips?
I have read that trying to tighten a bolt before loosening can break the rusty bond.
If you took the hub off you could grind them flat and use the new backing plate as a template to drill pilot holes which should be properly centred. Then a slightly smaller "easy-out" reverse thread may do the biz.
I don't have any backing plates behind the disks for the same reason.
Have had to deal with this one, problem with a MK2 is it is not possible to get anything directly over the head of the screws due to the drive flange. Considering the state it is in:
1. cold chisel and big hammer. Get good bite on head by striking directly at the head edge then change the chisel angle to turn the thread and hit it again. Not too hard, like an impact gun would hit it.
2. heat it cherry hot (don't melt that ABS sensor) then back at it with the chisel and hammer.
3. remove hub, pull the drive flange and bearings, grind screw head flat, center pop and drill out from front (tried from back and for some reason the bit ran slightly out). If you are good enough, I think just one of mine was, clean with tap. If you are not quite good enough coil the threads.
I took the opportunity to clean everything up while I was there:

I've got one side off the car but driveshaft seized solid. I also found a helicoil kit i must have bought years ago too.
Haven't managed to get the passenger side off - driveshaft again sezied to hub but disconnected from gearbox. The issue on the passenger side is the bolt that mounts the front bush on the wishbone is just spinning the bush and not backing out. I've tried all sorts - heat, impact gun, leverage on bolt. I've purchased and air saw to hopefully cut it out.
The car is putting up a fight!
Having to spend a bit more money on parts - everything is seized so renewing everything. Bearings, track rods, ball joints, wishbones, driveshafts. Joy. And this isn't even the mk2. I was hoping this mk3 would be a quick job since it is sub 80k to get out the way so I can work on my mk2.
I find these are good for shifting stubborn hubs, possibly cheaper on eBay. https://www.amazon.co.uk/CNWOOAIVE-Installer-Puller-Universal-Removal/dp/B08GFT5RKN/ref=sr_1_5?_encoding=UTF8&c=ts&keywords=Hub+Pullers&qid=1639992562&s=automotive&sr=1-5&ts_id=5136343031
That spinning bolt sounds like bad news
Cheers PWardy haven't been back on here for a bit - for £16 I've bought that to get me out of jail. I also decided to raid the penny jar and buy a freestanding 20t press. I have been eyeing them up for years for bearings etc.
I'm side tracked on the spinning bolt, The bolt for the front wishbone mount is corroded/fused inside the metal sleeve of the bush. The bush is so perished it spins in the wishbone when undoing. I thought no bother just cut either end so I bought an airsaw to cut the ends off but it's cheap crap or my aircompressor is not strong enough to run it (50l 9.6CFM) - the saw jsut stops when resistance is met. I then remembered I had a multitool but have blunt my remaining metal blade.
I only go out for an hour here and there. I've had Covid for 2 weeks and anymore than that I am knackered.
I've found this to be a good press. Technical support is good too. Price has shot up in recent years though.

Does look good that SGS one but out of my budget, I bought this one the other day
https://www.ebay.co.uk/itm/313453241660
It was delivered last night and I hope to build it today
Oh I didn't pay that much for it. Had it about four years, it was much cheaper. Paid for itself a couple of times over.
What you have will fit your bearings etc no problem. You will need something like this to make full use of it https://www.ebay.co.uk/itm/284354587584?epid=4011591923&_trkparms=ispr%3D1&hash=item4234daabc0:g:JHAAAOSwypJg3WtX&amdata=enc%3AAQAGAAAA4PCPYbfN5HrzPrSlRV0Cu95EE3u9rP3ouF7swlMVa%2B4i76EovCcYsn0xqO0LfJX98X0W3Dmg%2B0bF9q9MbKuXeMO%2B8Xi9vnI%2B3gfdVH3Nxm5eZpVmlN7kjCXb7PBahJ2%2B7%2FhVqDvklytaSeaUpQLA0mqgrAMM2%2Bj0%2Bq%2FtpYOuIkAI7KsWbWx%2FX28K4R0S29pc3I%2BEK6tk%2BAA2XugwkeGwNGpcN5knw%2B9BCZd3iCWNH3aLBdNA9%2F6UuM%2BWuWC7l2h6Dxz1y4EfOTxA2rj6ZPjmK7hYtE6STjH2jYwtrevlGPdV%7Ctkp%3ABFBM2uuiw71f
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.
(https://i.imgur.com/rw709K7.jpg)
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 ...
https://www.amazon.co.uk/gp/product/B013N9JSZ2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
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 :(

Did you get any instructions? Any idea what that plate is on either side of the base each with three screws?
No instructions either and that plate confused me as well - seems to serve no purpose

Presume it's so it could be bolted/mounted to something
The only thing I came up with is turn them over and position them front and rear on the press. The jig can’t easily then fall off forwards and back or inside.

I’m coming to the conclusion they are setup as I suggested above but are a safety feature. If the jig is not setup correctly or a support fails the gig could be shot out of the press unless those plates are positioned to retain it
