Grease leak

[CHOO CHOO]

Tony, question for ya. I had my mechanic put on the belltech drop kit I bought from you around mid-late last year. I keep having this grease slung all over the front passengers side wheel and the mechanic said that there wasnt enough room to shave down the rubber part anymore. He didn't shave down the nut and bolt anymore. Is this normal? None of the other sides leak like this. Heres a pic:

Let me know what you think and what I can do to get it to stop the grease from coming out. Thanks!
