Press fit wheel bearings suck... I have to pull out brand new front bearings on the megane because there is a pressed metal clip that holds the ABS sensor against the bearing (one of these bearings with the ABS ring built in rather than a separate ring on the hub...) is made of shit soft metal. Sensor flopping about and intermittent ABS light is the result... The clip is sandwiched behind the bearing, only way its coming out is removing the bearing first....
And being pressed in bearings, they dont come out intact so I have to buy whole new bearing, strip down and remove the hub upright and spend some quality time with the bearing press all for one tiny shitty little metal clip.
My own fault - I thought I'd found a cheap brand that was reboxing SNR bearings, but they were cheap chinese ones after all. Lesson learned - just buy the OEM SNR bearing!
