OK so there is 2 sizes of wheel bearing

Tapered

Inner Diameter = 37mm
Outer Diameter = 72mm
Height = 33

non tapered

Inner Diameter = 34mm
Outer Diameter = 72mm
Height = 33

But am I right in thinking it's the hub that has the tapered part on? So to change from flat seated to tapered I would need a tapered hub and a tapered bearing?

Or Is the taper part of the bearing?

Any help is appreciated :y:

After trawling though pages and pages..

The bearing itself isnt tapered the hub is

The bearing has a larger inner diameter to accomodate the hub having a taper

its the inner race of the bearing thats tapered to accept one of the two different styles of drive shaft end

either this shaft with the chamfer

or this with the radius

You will know by the nut on the end of the shaft. Ive just ordered 2 and they nut on the ends the same size as whats on the car now.

2 sizes nuts so.

bigger one, smaller nut

I read Alex' post aswell thats how it helped me lol.

I know what type of shaft's i have :y:

But to change a strut that uses a flat seated bearing / shaft to tapered then I need to fit a tapered hub with bearing to suit, the wheel bearing fit's between the hub/strut and isn't tapered - its the hub what's tapered :)

Basically

If you have flat shafts you need flat hubs
Which are where the taper/flats are

Bearings for both are square
But taper hubs are bigger so the bearing has a bigger i d to suit
Youll need to swap both
