2007 Taco, Starter issue

Hey,

Just wondering if anyone out there has had similar issues with their Tacoma's starters.

For the past two years I've dealt with a "tired", for lack of better words, starter.
The starter issue has been so inconsistent that I have not yet installed a new one.
It just always seems to have an issue with dampness, like after it rains, so this Spring , when I had some other work done, I asked the mechanic to make sure the ground connections were re-evaluated and secured properly, and I had no issues until yesterday, when we had the remnants of Tropical Storm Ida come thru. We had nearly 6" of rain in 6 hours and my truck just would not start...So I got out there today and tapped the starter a few times and Voila...it started...

I thought about replacing it myself, but for the lack of all the tools and a proper place to do it, I called my mech and got a price for a replacement.

I'm still a bit hesitant, because for the past few years, it has this weird issue and then a few cranks later, it starts...like every 2 to 3 months...fortunately I've never been stranded...it just starts..I don't know if I just have good luck or that it's not really the starter itself?

Anyone else here ever have this happen to them?
