3.89 gear question
I plan on purchasing the 3.89 gears for my 96 3.5 intrep but i dont know wether if i have the double chain or one in the trans. Would anybody here know about that? On the how to thread for the 3.89 gear installation,it stated that i needed: #4659834,#4659831 and do i really need this:#4659190. Also,at idle,there is a thump sound in the front on the passenger side and it seems to be coming from this device that is mounted on the air filter. When the car idles,you can hear that annoying thump sound and the 3.5's noisy lifters. Also,i plan on changing the lifters and was wondering have anyone tried to change it themselves and wether if i should take the chance to do it or take it to a shop which is what i'm actually trying to avoid.
