Whirring Sound from the rear

Post by Gjb » Thu Oct 10, 2019 5:08 pm

I drive a 2017 1.8 CHR Hybrid, owned from new with 34,000 miles clocked. Despite having completed a full service last month and having new Pirelli PZero tyres fitted I have noticed an audible whirring sound emanating from the rear of the car. It is increasingly apparent when travelling on smooth roads when the usual road rumble noise is reduced travelling at between 30-40mph.

I don’t think it’s a failing wheel bearing as the source of the sound seems routed central to the rear. Has anyone else experienced something similar?

Thanks in advance.
Regards
George

Are you sure its not the tyres? Often new tyres whirr a bit on smooth roads.
All the best

Noticed that same kind off sound from my CHR today it’s mainly when u let off the accelerator it’s not really loud.
But I’m a bit off a freak for rattles and new sounds. And this definitely sounds new.
To me it sounds like the old days when I had a Hi-Ace and the rear diff was starting to go.
Cars booked in for a full service in 2 weeks so will this will be top off my list.
Thanks Gavin.

Quick up date brought the CHR in to Toyota they confirmed it’s a wheel bearing.
They said it’s the first wheel bearing that has failed on a CHR That they have come across !!!mileage is 29000 km.
New one on order so will be all done when I drop it in for a full service next week.
