My hood on my jeep liberty will not complety shut? the only thing holding it down it the saftey latch.

Look at the hood alignment to make sure it's aligned properly and allowing the latch to catch. If the hood is fine you'll need to adjust the latch. Start by lubricating the latch mechanism so that it moves freely. Many times a hood will fail to latch properly because the latch itself isn't moving freely. Next check the area where the hood latches to the body and see if it's coming up short. If so manually adjust the latch until it's in proper position to grab and hold.

Try adjusting the loop that the catch locks onto,two bolts or screws and move up or down untill it works, then re-tighten. Allso give it some old fashioned grease.
