97 Trooper starter problems

I've Gone thru 3 starters since Apr of 04 (less than 20k miles between all failures), last starter replaced first week of Jan 06 - 4th having problems after less than a month. When turning ignition on, starter solenoid clicks for four or five trys then goes ahead and starts. Have tried to determine if there's a voltage problem - when last starter was installed everything checked good. Anyone had similar problems and if so, how solved? Open to all suggestions.:banghead:

Check you battery cables. I've seen vehicles with corroded cables do exactly as you have described.

hey my 98 trooper is doing the same thing just wonder if any body has any ideas, or if you figured anythig out. is it time for a new starter or is something else wrong. battery cables are good and clean, battery good, mine is a 98 with about 110k havent had that long. any ideas helpful.
