Starter selonoid

is it easy or hard to repace a starter selonoid, becasue mine is bad and i want to get is soon befor it wont start on me?

Its a medium task...you have to get under the car...but it'll be easier if you just remove the whole starter...

I would replace the entire starter with a reman unit (it will come with the solenoid). Many times the starter itself is the issue causing solenoid-like symptoms so replacing just the solenoid is a waste of time and money.
