Title: Rear wheel bearing
Post by: Benlake on April 13, 2022, 18:04
Hello my rear bearings are shot. I have managed to remove the hub (despite mr abs sensor and rear toe arm coming along) does anyone know how to remove the bearing? I have tried searching but not really understanding how it comes out. There is a clip that I can remove on the inside of the hub. Following that do I knock the thing from the front out the back? Thanks

It has to be pressed out.

As I recall -yes.  Though it should be pretty obvious which way it has to go.

Where the clip is - that's where it comes out. The clip is to hold the bearing in place.

Usually you have to press or beat the drive flange out 1st then press the bearing out.
Clean up hub, press in new bearing (On the outside of the bearing or it will damage it) fit the clip then press in the drive flange on the inner bearing surface.
A lot of bearings for abs fitted cars are sided and if installed wrong bring the ABS light on.

As there is no speedo drive from gearbox it has to take speed measurement from the wheel bearings/abs sensors.
If you connect a scanner and go into ABS you can check all 4 wheel speeds and see if one isn't picking up a signal.

I had a renault clio come in a few years ago and the abs light would only come over 70 mph, read all 4 wheel speeds over 70 mph the NSR was much slower than the rest.
Turns out they just had rear tyre replaced before the fault arose.. yep wrong size tyre fitted caused the fault.
Nice easy fix for once.

I don't have ABS on my car - deleted it. Also don't have an OBDII port as running an Apexi.

I do attach an oscilloscope to the sensor and get a signal, but no idea how strong it should be - it's about the same as the others.
