2004

Mitsubishi
Endeavor XLS
3.8L V6 All wheel drive
38,000 miles


Whenever the car goes above 35 mph a consistent squeak develops. It sounds similar to a loose belt. The noise began recently, it was not long after getting new tires and breaks. I am not entirely sure if this is related or not because noise stays consistent even when brakes are applied unless of course the car is under 35 mph at which point the squeak stops all together. Took into a mechanic, once the car was on the lift no noise. Mechanic said it is probably a pulley of sorts but it is hard to pin down until he hears it, his recommendation wait until something goes wrong. The burning question he could not answer is what is different at 30 mph than at 36 mph.



Any ideas,

ctreas; Noises are one of the worst things to try and find, especially if they come and go...It's possible that having the vehicle on the hoist, it is removing the weight of the vehicle off of the wheels. From your very good description, I'm pulling what hair I have left. But, I don't know that I'd wait until 'something' goes wrong.Unsure Has the mechanic taken it for a drive? You might want to go along, so you can point out the noise and say "that's what I'm hearing".

Thank you for the response, the noise may cause more damage to my mental state as opposed to the car's long-term condition.

I did have a mechanic do a ride along, he heard the noise and agreed that it sounded like a loose belt. What really confuses me about the diagnosis is how the noise goes away at the reduced speed and is non existent when the car is idling. If it were a belt or pulley should the noise be evident at all times when the engine or belt driven part (A/C) is operating? Regardless of speed.

Thank you for the input,

A belt/pulley noise would/could vary with engine speed, but vehicle speed wouldn't matter. If it is strictly vehicle speed, then it's in the drivetrain, not engine.

????: Change of attack - since this happened directly with new tires - check any trim rings - hubs, wheel locks or just remove all but the lug nuts. Make sure tire pressure is at max correct pressure listed for the vehicle AND that the tire is rated for that.

If noise still there with cosmetic parts off - try rotating the wheels and see if noise changes or perhaps goes away.

I also worry about how tight the lug nuts are. They should be checked by hand - not just an air gun,

Tom I did what you said and then I had a trained mechanic do what you recommended and nothing abnormal was found and the squeak continues. I appreciate your suggestions and I am open to any other ideas. If no one has any other ideas the next step is the dealer... and one can only imagine how much that will cost.

Sorry for reviving an old post but i have the same exact vehicle year and everything with the only exception of mine has 120k miles and im having the same exact problem as you. Same speed limit and everything. I was wondering if you ever found the solution. I read on a honda board of a post with the same problem with a honda element and his problem was a drive shaft bearing. Any luck with yourself?
