Re: Help., Howling 5KTQ
Is the noise load sensitive? At a given speed, is it louder under
acceleration, deceleration, or float (just enough throttle to keep the car
at a constant speed)? Most differential noises are load sensitive. Try
disengaging the clutch when the car is making noise ( release the
accelerator as well, of course!) to see if the noise changes.
Most tire noise problems are speed sensitive but not load sensitive. If
your noise comes and goes at the same speed, it could be driveline related.
