Grinding sound at low RPMs and during quick deceleration (even in neutral)
Hi, I bought my FRS 3 months ago with 92K miles on it. It’s been a while since I’ve driven manual so I couldn’t test drive it very well as I was too focused on trying not to stall the car (which I did 4 times during the test drive anyway). But eventually I got the hang of not stalling but I noticed whenever I started driving from a stop there would be a grinding sound. I assumed that I was using the clutch wrong and when I asked the previous owner about the sound he said “the cars have weak synchros and that sound is normal”
But the sound has gotten worse
It used to be whenever I would start out driving (typically after sitting for a while) I would hear this grinding sound for about the half second spent at 1000rpms while gaining speed. But now the sound seems to stick around between 900-1500 rpms and is much more prevalent. It doesn’t make the sound at higher speed or higher gearing or at least I cannot recreate the sound in those conditions.
Another thing is a similar, yet quicker fainter noise is made when I decelerate quickly, doesn’t matter if I am coming from 25MPH or 80MPH if I decelerate to a crawl or stop very quickly the sound will happen for a short instance
I don’t think it’s worn synchros because I have no issues getting into gear or staying in gear and to the best of my knowledge the car drives like usual. But I’m almost certain the sound comes from the transmission because that’s about where I hear it, could be further up so I’m making my best guess.
If anyone knows or has experience please help, thank you
EDIT: I forgot to mention! The sound has started continually happening while driving at lower rpms, driving at about 10-20MPH the sound is not as aggressive as it is when starting out driving but still there and quite obvious
