95 Legacy "wop wop wop" at 40 mph

[Sam Li]

Hey Folks,

My 95 Legacy AT, with almost 120k miles on it, will go "wop wop wop" at 40
miles per hour, about 4 or 5 "wop"s per second. This happens when cruising.
If I step on the gas the sound will soon go away.

Anyone know what the reason might be?

Thanks,

Sam

As in road noise? Can you feel it in the steering wheel too? I'd check
the tire balance.

My dad has a '93 Impreza wagon and sedan that both do the same thing. The
noise is independent of the engine (noise remains if cruising in neutral)
and the frequency increases with speed. The tires appear to be good on both
cars. I have not been able to figure out what is causing it.

I had a car that went wop wop wop at 40mph, I thought was from the driver's
side front tyre, but couldn't find anything visibly wrong with it, at 90mph
the driver's side rear tyre disintegrated! Luckily no other damage done!

Are you sure you don't have a nail in one of the tyres.

Tire or tires worn out of round.
Been there.
Not detectable by a walk round inspection.
I had mine checked by the tire shop and was told
it is not that uncommon on some vehicles and is due
to suspension set-ups.
New tires fitted....problem gone.

Mine just started doing that (rear-passanger side) after getting the tires
rotated and the passanger side ball joint replaced. That tire would have
been front passanger side, so I'm guessing it got worn differently than the
other three tires and that's what's making the noise.

Are you saying this only happens at 40 mph? Not at lower or higher
speeds? Is the sound associated with drive train, i.e. can you put it
in neutral and sound continues without change before slowing down?
