Afternoon,


I have just replaced my rear brake discs and repacked the bearings which were replaced 3 months ago. The hubs spin freely and easily. The job was relatively straight forward and I thought I was home dry. Until...

I reinstalled the halfshaft on the RHS, and gasketed and sealed the drive flange. When I went for a final test spin of the hub I could hear/feel a rumble/dg dg dg dg dg noise. I initially thought this was the wheel bearings, so I removed the drive flange again and spun the hub, all ok. I then spun the halfshaft independently, and the noise was there. It sounds like it's coming from the outboard end.


Here's a video:

Ignore the pad noise, but 'behind' that noise you can hear what I'm talking about if you listen carefully.



I used an endoscope to see if something was dislocated or broken, and I can't see anything untoward:










Any ides?

Bearings set wrong is my guess

Which bearings? As I say, this noise happens when I spin the half-shaft without the drive flange attached. So the noise is not wheel bearings.

in the vid it sounds like caliper is catching the disc

As I say, this noise happens when I spin the half-shaft without the drive flange attached, ie, disc not turning, just half shaft.

I'll take another video soon that might make it clearer. In that one it's hard to hear over the pad-on-disc scraping.

Was it there before you mended it, if not check what you mended.
