Agree with all the above on this...…. but will add...
Just went through having to replace the starter on my 5.4, it was just the solenoid but the cost of just for it was 80% the cost of a complete starter assembly...….. after checking things out, I went with Delco-Remy reman.....was $110.... is definitely a very high quality component! You can also purchase rebuild kits online and do it yourself......IIRR...the ones for our altenator/generator's run about $50.
