w220 wheel bearings

[hmang]

My dealer and gsf don't sell just the front wheel bearings for my 2002 w220
s class.

my dealer will sell me a hub assy with bearings fitted for just over £100 per side.

does anyone know the bearing no.s or dimensions so i can get them from bearing supplier.

or am i going down the wrong route here?

dimensions of the seal would be handy too.

and where do i get that luvly thick green wheel bearing grease that the factory use... it looks like good jollop!

I haven't done a 220, but most of these things have the outer race as part of the hub, so the bearing is not a removable item. BMW have a similar idea.

 

[hmang]

what muppet came up with that idea.

mine do look like ordinary bearings pressed into the hub though.

Strange you should ask this,Just been sitting in the little room reading this, EMail me and I will send you a copy.

but mate ...in the little room...too much information!!

talk about painting pictures with words

This is an article from SKF on how to change the bearings when they are inbuilt like yours, hope that you can read it OK You can check with SKF for the bearings.

If you cant read it I will post it

 

[hmang]

got it now.
it was rotten on the screen
but printed off its perfect.
why don't you post it up for others to consult i'm sure loads of people here would be interested.
or is there some copyright cobblers to prevent this?

i'm still not convinced my bearings are inbuilt or integral to the hub,
they just look like standard tapered rollers to me.

 

[television]

I will ask them, there are other firms that I am waiting to hear from as I have some very good articles just to make this forum the best in the world

 

[television]

I will look your car up and see what MB say

 

[television]

Just looked it up,it says.
Can be used again if the both the rollers and the bearing faces display a smooth light grey track.
No discoloration is found.
The roller cage and the end faces of the tappered rollers are not damaged.

It seems to say that the roller part can be changed, SKF could give you the answer

 

[hmang]

thanks malcolm

but it really does look like ordinary 2 piece taper roller bearings.
so they have to be available surely.

maybe i'm mistaken and the outer race is part of the hub

will look again a bit closer.

i'll be disappointed if the outer is part of the hub, thats just nonsense unless someone can explain an advantage to that method

It does not show seperate bearings on the parts site, so I guess they are integral with the hub at a list price of £139 + vat.

You will get a discount off the list, and this will also reduce your vat.

 

[hmang]

good news gentlemen

the bearings are now available from merc as separate parts.

the problem was the inner bearing (the big one) has a large radius on the face of its inner race.
this makes it a "special" bearing even though the size is standard.

the outer bearing is just a standard item

thanks for your input

Another good case of a little research that paid off, that's good news

Thats stupid, these bearings can be changed without changing the hub. Whoever told you that is either stupid or looking to make more money. But on the 220 it needs a press to put the bearings in and take the bearings out, special Benz equipment. Maybe they dont have this special tooling and thats why they said you must change the hub?

Eric if the inner outer case is damaged then its a new hub, anyway the job is done now

 

[hmang]

the "special" bearing is
SKF 32008 X/QVB458

it has an unusually large radius on the inner race which corresponds with a similar radius at the "shoulder" of the stub axle.

it appears that this bearing has only recently become available as a separate part, and up till now a complete hub assy was needed.

my dealer did not have stock and the new parts have had to be ordered from germany.

independant bearing stockist tracked some down in germany too but could not compete with merc price...(just over £10 + vat each)

the outside bearing as i said earlier is a standard thing
my car had
KOYO LM 12749

thanks to you guys and helpful parts dept at jacksons poole

hope this helps others in a similar position
