The inner oil seal of the bearing contains magnetic strips which form the "reluctor" for the sensor, and any dislodged rust particles will stick to the surface, and become trapped between the face of the new sensor and the oil seal, which leads to the rapid destruction of the seal. Much easier than pressing out a knackered bearing and fitting a new one too Brian |

Might be an idea to get a pair of hubs as spares. While I have a car bought specifically for parts, it proved so good mechanically that I;m using daily until next mot which it will fail on sill rot. |

Job now done subject to road test.
Contrary to some writings here, the sensor, at least the genuine one, is not a tight fit in the hole, in fact it is quite lose until the shaped tip of the sensor locates into the equivalent shape at the bottom of the hole. The reason why it would not initially go in was the shoulder of rust partway done left from where I used the large drill bit (see earlier posts). I coated the drill bit with grease then drilled again as far as it would, the start of the shaped hole being the limit. Hopefully the grease trapped most of the rust particles, but I gave the unit a further vacuum and wipe of the face of the bearing seal with a pipe-cleaner. Rather than copper-slip I used a thick coating of the protective grease NO-OX-ID in an attempt to prevent the hole rusting up again. The whole job did turn out to be quite straight-forward once I'd found or received the helpful posts from the guys on here - thanks (wish I'd found some posts sooner). Incidently, someone was commenting on Matt's (DMGRS) sensors not being genuine, I checked, and they are genuine; and at a very good price too. |

When I replaced mine a few years back, after carefully drilling it out I used the air line along with a vacuum cleaner to blow/ suck any debris out.
I also used the Dremmel to clean up the hole and smeared a spot of copper grease to prevent any future problems. |

Black protective membrane half worn away
On a Rover 75 CDTi I have a front drivers side hub from the breakers that needs to be fitted. I am cleaning the hub and ABS hole in readiness. Does it matter if the black protective membrane (in the photos by Arctic) is half worn away? Do I need to replace the black protective membrane? Is the membrane on the wheel bearing? Does that mean the wheel bearing bring needs replacing? Thanks

I would change the bearing while its off. that can be done by hand but i would recommend that it is pressed in using a hydraulic press to avoid damaging the bearing. some garages would do it for you for a small fee. you could of course fit the hub as it is and take a chance, but if the seal black covering is worn away, it has probably had a hard life already....

Thanks. I used the 32mm socket with a 2kg hammer and the flange and bearing came apart to see the bearing race having too much solidified grease. So needed replacing. Thanks

With all parts clean - when reassembling the sensor into the hub and then the hub to the driveshaft how much grease should be spread around the hub, bearing and driveshaft - so as not to interfere with the ABS sensor. Is grease kept off the side strip of the wheel bearing that is close to the ABS sensor? Thanks.

Dont put any in there.Just make it as clean as possible.the bearing is sealed anyway. Brush away any rust/dirt debris that you see. A little dob on the driveshaft splines wont i suppose do any harm. Make sure there are no metal or rust metalic filings around the hub /bearing and sensor faces.
