Why are ABS Sierra wheel bearings twice the cost of ex abs despite having the same number of parts???

Had a look through all the previous posts on this issue but still would like to know the cheapest place for them.. and, if I buy two for left if they cheap enough is to just a matter of getting the nut for the other side?

i asked that question at my local motor factors......was told that the bearings were 'very high precision units' required when using abs sensors...

dont know how true this is?

I didnt think the bearings were handed
mate and you dont have ABS so just get non
ABS bearings. As far as i am aware the hubs are the same for both.

Since the introduction of ASB bearings, most manufacturers now sell bearings for all ABS cars at a much higher price even though they don't have the ASB stuff on them.
