Have now ordered and received 2 new wheel bearing from separate companies, one using make and model, other using red number. Both are smaller than the one taken off the car :/ car is 2004 sti prodrive. Would there be any reason the hubs have been changed for larger ones in its past life???

 

Have you ordered WRX bearings and not STI?

 

1st one was ordered off ebay, gave info as 2004 impreza sti prodrive. 2nd one was thru euro car parts and gave info as reg. Both are too small from one I took off.

 

are they different then ??

 

As far as I know yes. WRX have R160 hubs vs STI R180 hubs.

 

it lists the same part numbers on opposedforces that's why I ask.

 

I'm assuming this is for the rear of the car? STI has a 72mm outer diameter bearing, WRX I think is 65mm.

 

Yes it is for rear. I'm gonna measure them, width is the same but bore is different
