Hi All,  I've noticed that when I brake fairly heavily there is a thumping noise from the left rear of my Brumby, it seems to be about wheel rotation speed.

 

Under light braking I don't notice any noise, it SEEMS the harder I brake the louder the thump and it only happens when I brake, not at any other time.

 

I'ts not a harsh metal to metal type noise, it's almost the noise I'd expect if the tyre had a bulge that was hitting something (If you know what I mean!) 

Have you checked the axle nut to make sure it is still tight?

i would raise the back of the vehicle and lightly apply the brake.  Spin the wheel and listen for noise,  if present,  then remove the wheel and drum for inspection.

Thanks guys, will do it when the rain stops!

Noticed the same thing on my 90 Loyale 4wd. Tightened the axle nut. The wheel bearing and axle was just changed and wasn't torqued down properly. Should fix this issue. 

You could have a dead bearing too. 

Definietly jack the suspect wheel off the ground and rotate it. I reckon the issue will become pretty obvious. 

Cheers

I did that, it all seemed smooth.

 

I did notice I could rotate the hub a tiny amount before the axle shaft turrned does this indicate excessive play in the outer cvj? 

 

There was no knock but there was that little bit of play.

Typically a CV joint beginning to fail will be more noticeable by a "popping" sound often more pronounced when turning one way or the other. I didn't notice in your description the exact vehicle, but I'm assuming you have a 4wd since you mention a cv in the rear? If the axle nut is tight for sure, I would recommend pulling the rear wheel and checking the drum assembly as well. I once had one of the brake shoe springs let go and made a thumping/clanging sound rolling around inside.
