Has anyone repaired a rear differential leak on their IS 250 RWD?
I think I have a rear diff leak on my 06 IS 250 RWD. A week ago, I noticed brown spots on my garage floor between the rear tires. I went by an oil change place near my house to ask them to look under there. They allowed me to go under there and see what was going on. The rear diff looked dry and clean. There was, however, some type of brown gunk on one of the two mounts located a few inches in front of the differential. They wiped off the gunk. I went home, cleaned off the garage floor, and taped down a paper towel in the same spot. The drips on the floor were dry and not oily. It seemed wet and chalky like road grime. I didn't see any spots for a week, now the spots are showing up again. I am making an appointment to have the car looked at this week. Has anyone else had this issue?
