This is my first post so here goes. 98' Suburban 2500 454 I dove about 100 miles today stop and start multiple times then i get home listen to the radio for about 3 hours and burban wont start. The starter motor clicks but wont crank. I just got new bat last week, amp are at normal level(even tried to jump start but not needed) I checked all the fuses and replays. Batt cables not corroded. When i was cleaning the starter (thought all the mudd might affect connections) a small rubber thing fell off the bottom of the starter where theres a hole. dont know what that was or iff its relevant just thought i should let yall know. I think its the starter but I wana c if yall have any ideas before i go spending 130 on a new starter.
