727 Making Weird Noise

oldkimmer said

Does the noise change when it shifts gears? Or with road speed. Have u checked ur power steering fluid level. Try turning the wheel lock to lock and see if the noise changes. The pump could be getting weak. Of ourselves this doesn’t apply if u have manual steering. Kim

Thanks for the input Kimmer. No gear N123 related change in pitch or tone. It does soften and/or stop when I bring up the RPMs. (Though the exhaust may be masking it) Then resumes when I slow and/or get off it. Just kinda starts humming softly and gets louder going up the pitch in the video. Other than the noise the transmission is operating normally. It's the darnedest thing.

No PS, manual everything.

Be well,
Pat
