I recently had to replace the starter on my 05 rubicon because it was chock full of dirt. I got the dirt in there from driving off road and there is a little pin sized hole in the starter where the dirt got in. After I replaced the starter a couple of mechanics I spoke to about it said i should spray a little wd40 in the hole after wheeling next time. I was wondering if anyone had a similar experience or could suggest some other tips to keep my Jeep running great after going off road. Thanx in advance!
