The 4 L inline six is NOT the same as the GM six. This engine is the original AMC 6, updated for use in the Jeep. This is an extremely rugged and long life engine which will run well over 100,000 miles, my grand cherokee with this engine gets 22 mpg, and it is a four wheel drive. It now has over 130,000 miles and uses no oil and runs quiet.
I have written about the brake warpage on my 2004 as well. To anyone who reads this, my solution was a "Very good set of after-market rotors". The OEM rotors just aren't beefy enough, and I have been told that the factory rotor castings are not as good as the after-markets. Use a good set of semi metallic pads as well. I have done all my own work on my vehicles for the last 30 years and have never came across this trouble with rotors. There are many good manufacturers out there so do your home work and take a very good look at your driving conditions. City driving is the absolute worst on brakes, you may want to go with a little more expensive rotor. It may cost more now, but could save you much more in the long run.
I bought a 2004 2WD Jeep Grand Cherokee Special Edition used about a year ago. The car has now 50K miles and bounces a LOT. Doesn't keep traction as well as I expected, also squeeks at times when I use the brakes or make a turn. Can someone tell me what the problem might be?
I got 2004 Grand Cherokee, and in cold weather it's making a tickling noise. And nobody knows what it could be.
I have a 2004 Grand Jeep Cherokee 4x2WD. I have had a couple of wiring issues since I bought it in 2007. The Jeep shuts off while in motion or while idling at a red light or stop sign. I purchased the top of the line tires to offset the terrible way the Jeep handles during the winter (very poor traction).
