leaking oil found on left rear subframe mount after tracking

chuang895 · 04-13-2014, 08:57 PM

Hi all,

Find leaked oil on left rear subframe but can't find the origin. Smell like diff or transmission oil.
Tried checking rear diff area but can't find oil leaks, but it was on a floor Jack so can't get really inside to check.
I did feel upshift quite rough and slipping on my second session to end till end of the day.
Any thoughts?

Probably popped the bushing itself.
They are fluid filled.

Orrrrr... Maybe your diff was overfilled and you boiled it? But I believe the breather spout is on the passenger side

if its a very nasty oil smell , its surely the diff oil that leaked of , since the breather goes on the top left of the sub-frame (driver side)
This is why its good to have a small catch can when something like this happen.
you probably overheated it or there was too much in it.

My bad, not thinking clearly about the breather side.

Thank you for the correction sir

Thanks guys, I believe it is diff oil, very nasty smell. I can remember that smell well since I just changed it last month. It was a hot day, track temp was 60 degree C, probably overheated it good.
I may have over filled it too, but Cant be sure.
Hopefully it's not anything catastrophic

My bushing smelled like *** too when I popped it. I have a new one if you need it.
