Hello everyone. I'm looking at getting a few ideas to keep troubleshooting a strange sound coming from what I believe to be the front wheels. My car is a 2002 2WD TR4. Here's a quick run down of what's been going on and what I've done so far:
At around 30mph a humming/tire noise starts picking...
So quick update. I put the car on jack stands, put it in drive and accelerated quite a bit (to around 50-60mph) and there was absolutely no noise whatsoever. I also noticed uneven tire wear on the front tires so I'm still thinking it might be something in the front that's causing the whining...
Thanks for the suggestions. Yea, diagnosing on a forum is tough but just wanted a few ideas on where to look since it didn't seem obvious what and where the noise is coming from. Good to know about the matching ratios too, I didn't know that this didn't apply to the 2WD. Just to be sure though...
That is EXACTLY what it sounds like. The only thing though, is that in this video it seems like the sound comes and goes with the accelerator (or at least that's what it seems like) whereas in my case, even if the car is in Neutral it still makes the same noise while driving at over 30mph.
I...
So here's a quick update on a quick visual inspection today. Other than checking the pinion bearing a few days ago, I noticed that the tires on the right side of the vehicle have uneven tread wear. They are a bit more worn towards the inside than the outside, I didn't notice this last time I...
Thanks for the suggestions everyone. I checked the pinion bearing by putting the car in neutral and there was no play whatsoever. I'll be greasing the u-joints and drive shafts today along with checking the rear diff fluid and changing it out if needed. I'll keep looking into it and keep you all...
Bump! Did you ever get this resolved?
I'm having a somewhat similar issue except mine is not dependent on the RPM's or being under load. In my case, at around 30mph a humming noise starts picking up and gets louder up until 60 where it slowly starts fading away as I reach 80 or so. I can put...
