REar hub differences

[Dougieboy1]

I am missing a hub for the trailing arm on my 72MY - it has ali trailing arms and i am putting it back to standard

According to the manual, the part number is 901-331-065-09.

Trying to find one of these is proving a little difficult but epay is littered with parts numbered 901-331-605-06 which look to me to be identical from the photos. I have seen it listed variously as for 68-73, for a 71 car or F-model 911

Are they interchangeable? Will 901-331-605-06 work on my trailing arm? Ofrdoes anyone have a 901-331-065-09 they dont want?

Thanks

Hi Andrew,

i don't know the answer, but i think i have some spare rear hubs if the 69-71 version will meet your needs.

The casting number on the part and the parts book number are two very different things.

thanks dave, i believe them to be the same part so am on the way to completion of the trailing arms!

In case it helps anyone else looking, the hubs are different from those used on LWB steel arms and those used on ally arms (none turbo). The easiest way to quickly tell is those used on ally arms have the additional lugs on the outer face to help centralise the wheel when fitting.

Just for file a pic for reference.



There is also a difference in the depth of the shaft that presses into the bearing. The actual width of the hubs are the same.



Hope this may help some one in the future.
