Squeal while coasting at 25 mph plus, hit the gas it’s gone ?

Hey guys, need some help with 03 auto Tacoma 2wd 2.7 mysteries squeal while coasting, 25 mph or greater it squeals and as soon as you give it gas it’s gone. Changed all the belts and there tite and we’ve eliminated the belts. Just spinning my wheels guys and would appreciate some help or even a shot in the right direction am green.

 

sounds like a ujoint

 

I had a similar issue for a couple years. Thought it was belts, then idler pulley. Mine would only happen during cold weather after startup or any extended drive 2+ hours. Same thing mainly while coasting or around 2100 rpm but would go away if you gave it some more gas. Greased all the zerks on my driveshaft and haven't heard it since.

 

You think that could be it ? Ok I will give that a shot tomorrow morning. Really frustrating noise. I’ve read some post on here and am not the only one with this problem. I really appreciate your time and thank you.

 

I had it, but i had completely sheared my ujoint. I had to have a new one put in.

 

I will look in to that and another member mentioned greasing all my zerks on the drive shaft.

 

Well, bring your grease gun, while you are under there you will be able to tell if you sheared on or not. Sounds like a plan.

 

Thank you guys I really appreciate your guys is time. I’ve been spinning my wheels looking for some answers and I got some. Thanks again. Good night and I’ll be back tomorrow with an update

 

Is the sound coming from the engine area or under the truck??

 

Had this exact problem, took the driveshaft off and cleaned up and greased the spline and never heard it again. This was after greasing the ujoint zerks and the problem persisted

 

If it happens while coasting but not while accelerating, it is probably the drive shaft carrier bearing.

 

If the u-joint is making a "noise",,, squeak, or whatever,, it's to late, their dry and scarred, replace them.

 

This could be the source of my squeak as well. I thought it was belts but noticed it was coming from under the truck and not the engine bay. I will have this checked out.

 

Random, because it would happen in park?
