igammie Posted September 26, 2014 Share Posted September 26, 2014 I see from attached Subaru service bulletin that Subaru changed specs from the 'Finger' roller bearings installed at manufacture to regular roller wheel bearings.I have the new part but I am concerned that the mating surface hub is radiused and that will destroy the oil seal it is against? That it will lead to premature failure? Anyone have any real word experience? Thanks! Quote Link to comment Share on other sites More sharing options...
igammie Posted September 26, 2014 Author Share Posted September 26, 2014 With brain working, I think I might have answered my question? I think the circlip should prevent contact? Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted September 26, 2014 Share Posted September 26, 2014 IMO , you're much better of with the old cylindrical roller bearings than with the new ball type bearings. Weight distribution across the bearing surfaces is better with the old style because there are 3-4 times as many rollers. The larger contact area makes the bearing last much longer. 1 Quote Link to comment Share on other sites More sharing options...
igammie Posted September 27, 2014 Author Share Posted September 27, 2014 My gut reaction is to agree with you. If I got 260K miles from the old fashioned type.....The newer standard roller bearing is easier to install, but....I'm undecided. Who do you purchase old fashioned tapered 'finger' roller bearings from? Which brands do you trust which have to best life in Subarus? Thanks! (I attached pics of the two types in case someone is confused - I have always called them finger bearings but I don't know if that was my family or universal?)

As long as you get a good Koyo or NTN bearing......either type will work fine for many miles. I personally like the roller as opposed to the ball type. Biggest thing is to support the inner race of the bearing as you press the hub through. If not, the outer bearing race will be loaded by the force of the press. 1 Quote Link to comment Share on other sites More sharing options...

Imdew, Given how little the parts cost and the relative ease of the job.... I'm not good at ignoring stuff, it's like an itch I have to scratch!
