Sometimes I get amazed at the things that people can screw up though. I've seen too many vehicles towed in after the owner/ neighbor/ cousin/ whoever got finished doing what should have been an easy maintenance repair.Your doing this all yourself right?
Save you lots of cash...all easy stuff to do.
(I don't mean to imply that is the case here. Just pointing out that what seems easy to some can be overwhelming to others. I try not to gauge to the comfort level or ability of others who I don't really know)
