I'm getting this subtle vibration on my 2003 Rav4 (automatic) when I'm traveling between 40-45 MPH and 70-75. It's not tied to RPM, only speed. When I take my foot off the accelerator at t

First record the rpm when the vibration occurs. Then while in park rev the engine to this rpm to see if it is there. If not then the engine should be ok. Next when on the highwaqy and the vibrations starts, put the transmission in neutral and see if it goes away. If so the go faster than when it starts and then put it in N and let the speed back down to 45 and see if it starts again. If it does then you may have a tire balance problem. If it happens while accelerating to 45 and goes away when letting off the gas it may be the u-joints.

Hi, you could check your engine mounts.

Have your Mechanic check the steering tie rod bushings, and linkage. Sometimes it's just an adjustment to the steering box play(located at the end of the steering wheel shaft), - easy to fix.

Our Rav4 2013 hood vibrates with cross wind @ 40 MPH. The latch is also loose.

any car the rpm shouldn't exceed the 4000 round per minutes and you can check it from the sound of the car if it's so loud you should decrease the acceleration pad or give the next gear if it's manual
if it's automatic don't panic

check for problem drive line "U" joints or cv joints

Most chances that the clutch is weak

chk ur tie rods, and ball joints..they r probablly bad . or u cud do a wheel alignmnet n balancing first.......that will solve ur problem

the vibration can be your tires, it may need balance, or the tire is out of round. I had seen the tires wear unevenly can cause this. what I mean is because this 4 wheel all the time design, if any of the tire is worn more than the rest can also do that.
the noise is a different thing, it can be a ball joint or tie rod end

check for loose engine / trany mounts
