I have a 97 v6 sohc. Here's my problem. After the truck is warmed up, if i go a few places and start and stop the truck, after the 5th start, the starter does not disengage. the truck starts but i can still hear the starter on the flywheel. This only seems to happen when its fairly hot outside and its been started a couple times within an hour or so. I am wondering if the starter needs to be rebuild, or simply replaced. If replaced, is it an easy job replacing the thing? Thanks for any help you can offer. Ryan
