Hi, can anyone tell me which cars have wheel bearings with 38mm dia inner, 42mm inner dia, and 46mm inner ?

Bought 2nd hand hub with 38mm on

But bearing from amayama are all 42mm

Z centre state 46mm

Totally confused cos I thought all were same size.

Look forward to any help.

For part# 40210-33P07

Thanks Andrew very informative,

I bought a spare knuckle took bearing out put new bearing in to find bearing is to big for hub shaft.

i can only assume the spare came off a Japanese car which have the 38mm inner,

And mine being a UK spec tt must have a 42mm. Won't know until I take it apart.

Very confusing especially when I looked on z centre and theirs are 46mm.

It does seem to be awkward buying parts for UK spec cars.

I will keep everyone up to date when I start refurbishment.

Many thanks again Andrew you are a star.

Nissan FAST shows my UK spec TT to be using either 40210-33P07 (NTN) or 40210-33P02 (NSK).

I bought 40210 33p07 from amayama these are 42mm inner diameter.

But spare hub was 38mm so no good , but at least I now know that when I change I can use my existing hub and they should be okay in new bearings.

Every day is a learning day

Thanks Andrew
