There's one here

with part number 411-501-283 E
which seems to be the same as a golf/scirocco

As far as i know, Timken is the only manufacturer for type 4 rear wheel bearings. They have a great on-line catalogue:
http://www.showmetheparts.com/timken/#

I've understood that the Golf/Scirocco rear wheel bearings are the same as the FRONT wheel bearings on type 4. The type 4 rear wheel bearigns were unique to these cars -as far as i know... I'd be more than happy if someone found some mass produced replacements!

Rear bearign seal is bit more difficult, but here you'll find its measurements:

Perhaps you could still get this from SKF-dealer.

Yeah - that rings a bell - when I did the 412, I ended up using early 80's Polo REAR bearings on the FRONT. Shame the Polo/Golf front's aren't the same as the 412 rears!
Paul - any luck finding bearings?

Mine has Polo rear bearings in the front as well!

There must be some rear bearings somewhere that will work though

Although from what I've been told the rear bearings on these are pretty much bullet proof and rarely cause a problem...famous last words!

Re-awakening this old thread as I think I will soon need to look at replacing one of my wheel bearings.

Thanks to the above I can see that I can get the seals from SKF and the Timken parts number

I have also found that SKF now have the equivalent parts finder at http://www.skfpartsinfo.com/ which results in listings for both the seals and the bearings themselves. I'll nip round to my local bearing dealer tomorrow and check availability for the SKF versions (which appear to have the same reference number as the Timken) and update the thread.

This "looks" to be a fairly straightforward job. I suspect the initial challenge will be undoing the CV bolts though my tools are better these days so I'm hoping that they aren't already chewed up and will be easy to do. The centre retaining bolt is free to move so I know that will undo and assume the wheel shaft will just pull out and will not be rusted in and the outer bearings can be readily removed from the retainer.

What are peoples experience with removing the inner bearing components. I'm assuming the taper roller bearing will just pull away, but what about the outer race ? Does it drift out relatively easily, will it need encouragement from a bit of blowtorch heat, or might I be into a situation where I have to remove the whole wishbone to get the bearing pressed out. :(

Not great news from the bearing supplier (Antifriction). Appareently he has access to the industrial rather than automotive division of SKF.

He cannot identify the bearing from the SKF part number, nor can the seal be identified from the part number.

Apparently Timken have 1300 bearing sets in Europe, all we need to do now is identify where to get the seals reliably

Bearing seems fairly available in the US

I have saved this bearign seal to my Ebay favourites:
http://www.ebay.de/itm/Wellendichtringe ... 58a12a2352
This should be the correct seal but it's been a long time since i ordered these so check your oil seals' markings before ordering.

Thanks for the additional information, my knowledge of technical German is expanding all the time :)

I went back to my Antifriction this morning, with the SKF spec sheet.

They have offered me an imperial oil seal, reference 25018737, size is 1 7/8" x 2 1/2" x 3/8" which converts to 47.6mm x 63.4mm x 9.5mm

You can see the details at http://www.bearingstation.co.uk/product ... al25018737

This would seem to be a readily available alternative, not quite as deep as the ones on ebay Germany (though I don't know if in reality that matters or not)

I'm trying to get the bits ordered and ready to install before I start tackling disassembly as I don't want to end up with an immobile car on the drive.

Any voices of experience as to whether getting the old bearings out is going to be difficult or easy ?

The bearings should come out easily as they are not pressed in or anything. For me it was more difficult to get the seal out as i didn't have any replacements back then. Do you have a workshop manual? I have some digitalised so i can send you a copy if needed.

I'm delighted to hear that the bearings should come out quite easily (inner & outer ?). I think I'll be careful when removing the seals, "just in case". It might also be possible to get the reference numbers off the original components. Interestingly, but people I spoke to at the bearing supplier immediately said that the bearings were an imperial size, not metric, which doesn't make any sense to me for a VW.

I don't have a workshop manual at all, a digital copy would be wonderful. I'll PM you an email address, thank you.

The styling design was done by an american company, but I wouldn't think the mechanicals would have been.

That's what I thought, but the evidence seems pretty strong based on a search for the Timken LM78349 / LM78310A part codes;

http://www.astbearings.com/product.html ... 9_LM78310A

http://simplybearings.co.uk/shop/produc ... s_id=40336

http://timkenparts.com/index.php?MenuLe ... y=NLM78349

They all refer to the parts as imperial bearings, even if, at least according to the SimplyBearings site the bearing seems to be sized in mm

I suspect that the LM is the part that describes the bearing as imperial size.

Perhaps we shouldn't be afraid of using an imperial seal - at least they are readily available :o

All the brake hydraulic cylinders are imperial. eg 22.2mm =7/8" and 19.0mm = 3/4".

I broke one of my 411s earlier this year and didn't find it difficult to remove the bearings, which were in good condition.

That's good to hear. I have the bearings now, just waiting for some time and daylight to fit them (aren't the nights drawing in)

How did it go? I have one side that needs doing. Was thinking of just tightening it up. But if you found it smooth enough to replace, I think that'd be the better route. :)

Sadly I cannot tell you as my desire to keep the car available for use means I have not tackled the job yet, sorry. :oops:
