So before the winter season hit, I saw grease all around my rear passenger side wheel assembly. I cleaned it with the anticipation of seeing if it comes back and it has yet IDK where its coming from. Its not an axle boot because the boot and wheel hub area is clean but its just the back side of the wheel hub assembly. I thought it could be grease or even brake fluid from caliper but I inspected that too and those are all fine.

I might re grease and redo the clamp on both boots to make sure but Its not them.

The shocks are fine and not leaking. Does anyone else have this problem.

Rear Right


Rear right axle was replaced before I got the car and has a black clamp on it so thats why it looks different.

 

Unfortunately I cannot see much going on here from the supplied photos.

 

The Bottom picture, the wheel/hub knuckle is all black covered in dirt and a grease like substance how ever the left one is clean. did it for comparison

 

Only thing that would cause that are the axles leaking grease. Lexus does not offer a boot kit only full axles. However it does look like the drivers rear shock is leaking.
