Rear bearing replacement

Post by alin_999 »

Hi guys!

I need to replace the rear bearing, but I do not know the size of the hub nut. It is smaller than the front one.

Also, is there anything special to know when replacing a bearing? Anything I should be careful about?

Thanks!

Just make sure you tighten everything to the right torque

Hum, it looks like on that video that the rear axle stub is short enough to do this job with a normal bi-hex 30mm socket, I have just ordered a Laser Tools deep bi-hex 30mm socket to do that job on a late 2009 SEAT Ibiza (rear brake proper service!), and then discovered that Halfords looks like it sells a "good enough" 30mm deep socket which is probably a 12 point bi-hex for £1.50 less than I'm paying for - and I could start that job today instead of end of this week!!

Edit:- I'm not really interested in starting that job then discovering that I should have used a deeper than normal 30mm socket!

I was surprised it was only 70NM + 30 degrees for the 6R0 Polo, same for this one?

Yes, it's the same on the Polo 9N/9N3, since they share the same wheel's hub.
The 30° you have to add on the 70Nm make the torque more than appropriate. ;)

Good!

The car I am going to sort out the rear drum brakes on is a late 2009 6J SEAT Ibiza, again same hub etc, I know that I can not adjust the rear drum brakes by moving the wedge down, so I need to get in there and see what the problem is and fix it.
