The boot has no splits or cracks. He thought it might be from over lubrication from factory. Its definitely thick lube grease. I can honestly say all the times I've been under the car, still not sure how long its been there. Thoughts?
Is the strut leaking? It looks like that would be the low point it would gather to.
It would then drip on the axle a get thrown off onto the different areas.
Thanks. I didn't see anything obvious but I'll look again in the daylight.
WOW, did you figure it out? I have same thing, boot in perfect shape, great all over the place and on wheels, what?
