First: I had purchased this vehicle used with approx. 110,000 miles on odometer. Steering wheel violently shakes on moderate to heavy braking as well as moderate shaking upon deceleration on highway surfaces as well as interment clunking from frontal suspension area under similar conditions. The steering wheel may be pointed straight ahead or at a slight left or right position. There are times when the shaking, under the above conditions, is very slight or nonexistent at all. I believe it is in the front steering linkage/suspension and not the brakes. I have personally inspected the components mentioned above as I have mopar experience in the past as a technician. I have also had a second opinion from an independent technician well versed in Jeep technology. Second; I also have a problem with the oil pressure being erratic when warmed up and either stationary or in motion. I have replaced the oil pressure sending unit and performed mopar diagnostics on the cluster as mentioned in the shop manual to no avail on this 4.0L engine with automatic transmission.the gauge reads well when cold but when warmed up it will drop to zero with the gauge alarm warning me of the action. Then moving erratically between the 40lb marker and zero pressure while in motion or stationary. I and a few technicians are having difficulty determining where the problem is generated. On a note, there is a slight consistent ticking noise such as a valve lifter or rocker arm coming from the engine, warm or cold, stationary or in motion. It occurred when I purchased the vehicle and is still occurring today. Thank you for any consideration that you may provide to me as this is my only means of transportation and I am handicapped.

I was driving on an on ramp when I hit a raised bump on the road. The front started bumping violently almost like a basketball. When I applied the brakes it stopped as I slowed down. It happened once more as I could not get off the highway from the first incident. Again, I hit another bump and the same thing happened. I was lucky that no one was right behind me or there might have been a collision. I went online when I got home to see what the issue was and from what I saw it was what people call the "death wobble".

Tie rods, wheel bearings, ball joints, fan clutch, shorted engine compartment wiring harness, fuel pump assembly all gone wrong from time of purchase; January 2000/brand new to Sept. 2006...some pd. Under warranty others after 2004 not; even though the defects usually do not happen to a Jeep Grand Cherokee/fully loaded. The last straw was the ball joints; we asked if some form of recall should of been done and then asked for a reimbursement because my wife's' 2004 Jeep Liberty limited had a recall on it's ball joints/lower ones so after having mine replaced last Friday 9/15/2006 we asked about the Grand Cherokee and it's ball joints; we also updated on all the defects we've had to correct and wondered if it wasn't a expensive lemon...$35,000 is what I paid. We called Chrysler main customer service and was only told were sorry, the age of the Jeep and past warranty...what does that have to do with all the past defects since 2000 and the fact we tried their customer service in 2002 and got no where again. No matter the age of the vehicle...safety is safety. And if ball joints go bad for no reason and have to be replaced then, it should go as a safety concern for all their vehicles.

I bought the 2000 Jeep Grand Cherokee car brand new, one year later we had to have the rotors replaced, six months later we had to replace the brake pads. Six months after that, the automatic door lock on the diver's side started making loud screeching noises whenever you lock and unlock the door, a dealer looked at it and estimated $700 to have it repaired. We've been having fron suspension problems, and the transmission makes a humming sound when it's in reverse. What's next?

Power steering pump broke on vehicle. While driving the consumer completely lost the power steering on the highway. The power steering had a kink in the column and could be heard when making a turn. The power steering hose was replaced along with the steering pump. The consumer was informed that the front left tire was bald due to improper alignment. There was a whistling sound under the hood when the vehicle was idled. The water pump and the clutch was replaced due to bad bearing. Also the rotors were replaced.

Jeep pulls to the right, can't be fixed. Caster camber out of spec. Dealer tried to tell me Chrysler designs the vehicle to pull to the right, when I didn't believe that, they told me it was the crown on the road. Nlm
