E21 hub size for non Tii struts

[D12typ]

Afternoon all, based on the pics below, would these work for my non Tii struts for the Volvo brake upgrade please?

Funny- that's a perfect way to ask, but I was looking for the 'cheater' details

(like the dust cap) since I don't remember the exact measurements!

BMW parts 3' E21 320i Wheel bearing

 

and the inner seal's outer diameter is 40mm, 

which kinda matches what you have in the top pic, and 

 

yep, looks like it'll work.

 

(The summer I worked as a carpenter's apprentice, Scott taught

me to 'burn an inch' so you could see the start and end markings

on the tape measure clearly.)

 

If you look at the earlier hub, it has a 47 mm seal, so quite a bit bigger.

No, in my cheater method… the od/id ratio on the inner flange (thin) indicate these are the larger bearing hub compatible with the tii strut.  Your looking for hubs with a thicker inner flange.

 

edit: ignore the calipers/rotor, and focus on the hub in the photo here.  Notice the thicker inner flange… that’s what you’re after.

 

by last count that still makes me eleventy billion in the hole on being corrected by sensei Toby… but every bit counts!

Thanks gents so you think I should be able to use these. A breaker sent me the pics but they come from a European 320 and doesn’t know year of vehicle so Im hoping you can point me in right direction. 🤗

No, they will not work on a standard 2002 strut.

Thank you for confirming

This is what you need, I hope, as these are what I have bought for the job!

Oh, shit, I can't do math-

 

no, they are the 47mm earlier versions, so they won't work.

 

65-15= 50, not 40

 

durrr.

Toby, is that in reference to my pics or the OPs?

[TobyB]

op, from the initial picx.

 

The rear shot's adequate to figure out it's an early hub,

but I did math in my head... and failed.

 

Andrew's also right- the later hub noses are turned down thinner,

whereas the early ones are (often, as in this case) not.
