Loose stearing My jeep Grand Charokee Laredo's strearing is very loose. I have found out that it is not in the stearing wheel. I took it in and they were only able to improve it slightly.

The speedometer on a 2004 Grand Charokee gets its signal via the PCI data bus from the ABS control module. Both rear wheel speed sensors are used for the speed signal.

Yes, the PCM is specific to each year, make , and model , and when ordering a new PCM always use the VIN# and production date to make sure you get the right part.

Start with the basics, when the car dies, check for spark, fuel, and compression, that will point you to the problem.

Base (initial) ignition timing is NOT adjustable. Do not attempt to adjust ignition timing by rotating the distributor. All ignition timing functions are controlled by the Powertrain Control Module.Adjusting the timing on a Jeep Grand Cherokee requires special tools and an understanding of engine mechanics. Changing the timing on a Jeep Grand Cherokee with distributor-less ignition requires professional reprogramming of the powertrain control module. This guide covers Jeep Grand Cherokee models with distributed ignition only. you can go to this site and it will explain it. www.ehow.com/how_4521340_adjust-timing-jeep have a good day !!

I've had my 2005 Grand Cherokee into the dealer 5 times for the same issue and they've replaced a bunch of stuff, but have not found the problem yet. A quick fix, I've found, is to jiggle the key in the ignition. Doesn't fix the problem, but it does stop everything from going crazy! Let me know if anyone has the actual fix.

Check your spark plug, wires, distributor cap and finger. If you spark plugs older than 15000ml, replace them. To check your spark plug wires, use a tester (U can buy at any auto store) you hold direct on the wire and a small sparkling will show you if the wire works or not. You can check the wires also with this: use a single spark plug (don't remove one out your engine!), remove the wire from first SP, connect it with the single SP, hold it to ground, let someone start your engine...you need to see regular sparks.. do this step by step with all 6 wires. If all wires are fine, check the SP's, If you miss on one wire, replace the wire, if you miss on more than one, chekc the distributor cap and finger. If this items are older than 20000ml or 5 years, replace them.

The center pully is the IDLER PULLEY.
It is also referred to as the TENSIONER.

It has a coiled spring that creates the belt tension. Replace it ($15) (and the belt) ($8).

Hope this helps!

have you changed the thermostat? is your fan kicking on? if your fan is not kicking on you need a temperature sensor.

check the steering linkage and idler arm pitman arm for play

You might take a close look at the ball joints on the front suspension/steering arms. I've had the same problem on another vehicle. Also you should check the front wheel bearings for loose play.
