tough, but need help in identifying this sound..
For the past 4 weeks, I've been hearing this sound from the rav4 and it is getting worse. I've checked tranny and engine fluids, each is at the correct level. Have not checked the transfer or rear diff fluids.
This is the scenario: When the rav4 is coasting between 15-45 mph, but set at a speed (e.g. 35 mph), I hear this somewhat rattle sound as i gently press on the accelerator (hear attached sounds, they are not the greatest, but currently the best I can do). The sound is very distinct and is very reproducible to hear and lasts for +5 to +10 mph (especially if there is wall alongside the road so thecan bounce back to the car). I've noticed it seems to be related to the RPMs, for instance the rattle sounds generally occur between 1200-1600 rpms. Im concerned if this is related to the transmission gears; in this case I suspect it is 3rd gear (in my situation, ibelieve I am in 4th gear when coasting and 3rd gear when slightly pressing on the accelerator). I've noticed when climbing uphills (greater load) the sound also is generated.
Can anyone identify what the sound might be? I realize the recording is rather crappy (via iPhone) due to the wind, but replay each and you will hear the rattle sound. I plan to take it to dealer, but wondering if someone could give me some advice, lately dealer has pushed back on a lot of issues. many thanks...
