Not to get off topic but I have to diagree with CDW. I think front end work (brakes,ujoints,struts ect.) and maintance is the highest profit per hour work in the auto industry. I have pulled many trans and installed prebent pipe, I have even bent custom pipes and still think for time spent, front end work is alot eaiser and makes more $$$ than any thing else.
Back on topic, I am glad you got your leak fixed. I know how shops can rip someone off, I have seen it done. Never hurts to get a few quotes and shop around.
