I have a 1995 jeep cherokee with roughly 133,000 miles on it.It is a 4 liter 2wd. The problem is that whenever i turn the car off and turn it on there is a rattle or clunk sound at the end of the turn on/turn off process. I was wandering what this could possibly be? The car starts fine i just think that this could accumulate to a problem in the future.
