Hey all,

I've got a 2011 IS250AWD, lowered on BC BR Racing coils. Distance from fender to ground is approx. 26.5 inches.

I was just checking my boots, and just going through a standard check and noticed something odd, and was hoping if some people could chime in on what it could be....

The image below is shot from the front driver side wheel well. I have the wheel cranked to the RIGHT all the way, and noticed this little ****, looked a bit out of place. I touched around it and was a TINY bit of grease stain, and even from the photo it looked a little 'greasy'. I took my hand to feel the ****, and it seemed to spin freely... If I push down, it feels spring loaded, and i tried to spin the 'base', the bottom part, and it doesn't budge.

At this point I'm a little concerned, could anyone chime in and explain what this could be? Thanks

 

I should also note, everything else underneath the car is bone dry, no boots are leaking, no shakes when i am driving.

 

Looks like the breather for the front diff.
