My 2007 RX 350 with about 120,000 miles has started to make a sort of rumbling noise when I come off the gas. It is most noticeable it when I come off the gas and am coasting over 30 mph. If I get back on the gas it goes away. Also, the noise goes away if I drop it into neutral. Any ideas what could be causing this?

I tried making a video of it but it’s not noticeable in the video.

Thanks

If this is FWD, maybe the CV axles? If AWD, then transfer case could be a suspect. I would wait for it to get worse before messing with them. Do check the ATF tranny fluid level, 2007 has a dipstick. I would get it jacked up on front and check the control arms too.

Thanks I’ll definitely check those things but after poking around online it seems like it is similar to the sound shown in this video. Could it possibly be the wheel bearings? It seems like if it was I’d hear the noise while neutral and coasting.
