Hissing sound

[dreamwarrioruk]

exhaust got an hole in it.?
pressure built up in the rear axle causing blow out of the breather.?
cant think what else there is on passenger rear side.

Incidentally, same noise here, "hissing" from beneath passenger seat. Couldn't hear it when I had a squeaky alt-belt, popped some wd40 on that and then could hear this hissing. Generally more noticable when under load (i.e. when pushing up a hill, or accelerating) than when cruising/slowing.

I think it might be coming from the alternator itself (bearing?), but not really sure. Someone here has recommended a funnel on a hose stethoscope type thingy, so might give that a try.

Could it be the anti squeal plates on the rear brakes ? I've had this for a while, and have learnt to live with it. It disappears when I brake, or am travelling above 30mph or so.

I had a hissing noise on the left hand side, turns out it was the misses moaning.

I think it is the rear brakes, so going to get the rear brakes checked, just had front done

Well just been out for a short trip today, Laura was sat in front, noise started after about 4 miles. Laura said it was coming from the front passenger wheel, not the rear Having just had the front brake pads replaced I reckon that is where the problem lies so getting it checked tomorrow richrich I reckon you may be right about the anti squeal plates
