Humming noise on left turns. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

kphan · 10-25-2016, 03:19 PM

I have an pulsing humming noise whenever I am turning left from the LEFT wheel driver side. You can feel a slight vibration. I looked up to see if this was a wheel bearing issue but it seems like it would be the right wheel that should be making the noise. It pulses which make it seem like a tire issue and the rate of pulse increases with speed. I recently did get suspension installed. Anyone have any ideas what it could be? Thanks!

You should mention ALL the parts you have installed.
What have you checked?
Did you get an alignment after the suspension install?

Was in a rush to post and forgot to specify. All that was installed were TRD springs. I had a mechanic friend check out alignment. It could possibly be that, I just wanted input to make sure before I go and do it.

I am asking what other parts do you have installed? Wheels? etc? What do you mean by "I had a mechanic friend check out alignment." ?

Get an alignment...

I suggest you get an alignment and mention to the tech what the car is doing.

Only ideas I have are, wheel not mounted correctly, wheel balance off, tire pressures, suspension loose from install, alignment off... , or other parts...

Everything is stock including wheels. Only modification are TRD springs. What I mean by mechanic friend is that he works at a shop. He lifted the car, checked the alignment of wheels and told me I was good to go. I've never done an alignment myself so I do not know what that entails.
Tire pressures are normal levels. Car has 23k miles. Sounds are a like "Whoombb.......whooomb....." etc. It happened after installation of the springs.

Front or rear and at what speed?

Could just be hearing the LSD doing what it's supposed to.

Did this "mechanic friend" scan the wheels themselves? Give you a telemetry sheet of the toe and offset? Or did he just look at it for a minute and say "yea, it looks good to me."?

If the alignment isn't correct than there could be possible rubbing issues either with suspension components or with the fender itself. Not saying that's exactly what's happening but you shouldn't take something like wheel alignment so lightly.

And who installed the TRD springs?

Front. It typically is more noticeable at higher speeds but can be heard on slower turns as well. It only happens when the wheel is positioned left at any degree.

Yeah no information on it. Just trusted his judgement based on his history. I will probably get an alignment here based off of everyone's suggestion and hope it fixes the issue. I installed the springs myself but its definitely not the first time I've done it.

Thanks!

Yeah you need an alignment. It might not be what's causing the issue, but it's a good first place to start, and something you need anyhow!
