Whine from RHS while turning right

[Baron von Teuchter]

Slightly odd one this. My Grenadier is 3 years old and has done 19,000 miles.

Intermittent whine at speed, only when vehicle is warm. Only happens with a little bit of right lock on, doesn’t matter if on the throttle, steady or off the gas. Braking makes no difference. Doesn’t always happen, sometimes it will do it at manoeuvring speed, sometimes it will do it at 60mph.

Pad looks OK, brakes feel fine. No feel of metal on metal, no vibration, no undue heat (though I haven’t used the temp probe), no smell.

I wondered at first if it was a stone in the brake disc but if so it’s not obvious.

Any suggestions? Wheel bearing maybe but it’s not a grinding or clicking and it’s only done 19k - I’d expect bearings to a lot longer than that.

Rust on the outer rim of the disc? Although that tends to manifest itself under braking and is more of a sequel than whine.

Hmm, not obvious no and I’ve driven 100 miles today and it’s still doing it (sometimes)

The other thing I would try, to make sure there is no stone trapped somewhere, reverse as fast as possible and then brake hard to dislodge anything that may be trapped out of sight.

I’ll give that a go, cheers

Non adjustable wheel bearings when worn do produce a whine when turning. If you jack the front wheel up and turn it by hand you would feel a slight roughness. As you suggest, it is unlikely.

Thanks Landman, I tried just front right wheel but not the others, will give it a go.
