[QUOTE="Genesiss, post: 443706, member: 22628"] I ended up ordering a rebuilt engine since the last owner ran it 3 quarts low and it had almost 200,000 miles on it with those cat issues and the jerking, knocking and p0016 code. Allowing Aamco to install it. They discovered the flex plate was trashed in the process and the timing chain was very loose so rebuilt engine, oil pump, flex plate, torque converter, trans cooler then a new water pump and thermostat since they are replacing the engine anyway. The next question I have is since it’s a Dana 30 on the front end Dana 44 on the back with a 3.73 original gear ratio according to the factory sticker on it with the towing package what gear ratio do I need to confirm? I have Ironman 37’s with Dana 30 and 44 I assume based on what i read I can go to 4.88 or 5.13 however most say 4.88 is better and some say 5.38 is needed for that tire size hub that means switching out the Dana 30. I really just need advice on what I need to do to ensure a dependable vehicle that my wife who really wanted that will not leave her stranded or have a catastrophic break down. I would prefer mpg over power. Any advice is appreciated. [/QUOTE]
