Shuttering when turning - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Sorry if this is in the wrong section, I have a 2016 frs just rolled past 1k km. I've started to notice when I take a sharp corner slowly I get almost like a shuddering coming from the back end almost as if something like abs was kicking on, on just one tire. It only happens that I notice at very slow speeds under 10km and when I'm backing out onto the street from my drive way or pulling into it, or pulling in or out of a parking spot. I noticed it did this the first day I got it when I pulled into my drive way but haven't notice to much of it till last week and this week it has done it about 4 or 5 times. I'm not sure if it's an issue with maybe the diff? Or maybe one of my brakes is not releasing? I do have the trd brake pads and they make an ungodly sound when doing light braking, all the time not just in the morning but through out the entire day of driving, but I just assumed maybe there not seated right? But I can put the car up and the tires will rotate freely no scraping or chafing. I hope it's not an issue with the diff, any ideas?

That is the sound of your limited slip differential doing its thing.

I don't know to much about LSDs, but at very slow speeds and enough to vibrate the whole car?

Yes. Torsens at low speed will do that. Clutch type is worse.

Good to know, thanks for the input guys

Mine does it, and I assume everyone's does - no worries, brother.

The interesting thing is that my 2015 definitely shutters more than my old 2013. I don't even think I felt it on my 2013...

Interesting. I sometimes wish my diff was 'tighter' and I have a 2013. I just put it down to being used to plated diffs.

It will smooth out some as you put more miles on the car. It also will do it worse when the diff is cold in my experience.
