Some minor issues.. please advise

Hey gang
Need some input
1) loud noise like I'm driving on gravel/ vibrations at 35-40 mph then it goes away.
2) when it starts, noise sounds like buzzing from radio then goes away.
3) no air on feet but airflow works everywhere

 

1- sounds like you might have a bad needle bearing. This is a known issue with some 4runners. Find a straight stretch of road, and throw it in four-wheel drive at about 30 mph and see if the noise stops. If it does, it is the needle bearing.

2- sounds like the EVAP pump. Emission stuff. It runs for about 10 or 15 seconds. When you start up, then it shuts off. Then, it also runs for a few seconds after you shut it off.

2nd this and the Needle bearing is a rather easy fix if you have a lift available even better this is where I have purchased a few from ... https://eastcoastgearsupply.com/i-8536125-toyota-8-clamshell-bushing-eliminates-needle-bearing.html

 

1) I don't 4x4 it's 4x2. Is it expensive to get fix at local mechanic? I'm total noob.
2) EVA pump, can this be big trouble later?
3) i guess I don't need to dry my stinky feet!

 

-The needle bearing makes noise in 2wd (mostly). Putting it in 4wd helps diagnose the problem.

-It's tough to tell if we're talking about the same thing. But, there is a pump that makes noise when you first start, and also after you shut it off. It's not a problem. That's what it's supposed to do.

 

Got it. I don't 4x4 mode so it must be it. Can it be bad if I don't fix it? I wonder how much it will cost?

 

If you have a 2wd only 4Runner, then you don’t have a needle bearing, so that is not your issue.

 

Oh! What is issue do you think? Goes away after 40mph

 

Wheels out of balance. Wheel bearing issue. Loose LCA. Failing CV... could be a ton of things. We need more info from you. Whatve you looked at? Pictures? Recent changes?

 

Do you have an aftermarket roof rack or a basket or something? I get a huge harmonic hum off mine at about 35mph. Surprisingly loud.
