Is it possible for someone to have damaged my rear compression control arm? Because I have not hit anything for it to break in half the way it did.


Rear Suspension

Anything is possible. But it would be difficult for someone to cause a small enough amount of damage in order for it to break at a later date in time. It would be more likely that a pothole or parking block covered in snow would be the culprit. Maybe someone else was driving and mistakenly forgot to mention it.

The knuckle, camber link, compression link(8) and tension link are aluminum castings. Extra care needs to be taken when servicing these components. The wheel and tire mount at the end of the knuckle(7).

Unless you have recently had some work done, I do not think anything was done to it to cause it to break.

Stalls and dies

I have a 1999 Chrysler Town and Country lxi 3.8 engine. Every now and then when I come to a stop or slow down to turn my van stalls and dies. But when put in park or neutral it starts right back up with no problem. When I go to pull it into gear it stalls real quick and dies after several attempts it finally goes.


First thing to do would be to have the check engine light codes scanned. Any code stored may assist in directing you in the right direction. Post any code found below in the comments for further assistance.

Some possibilities if no codes are present may be but not limited to:

  • Dirty throttle body needs cleaned
  • Sticking or faulty IAC – Idle Air Control
  • Faulty TPS – Throttle Position Sensor
  • Faulty MAP – Manifold Absolute Prsseure Sensor
  • Vacuum leak

Engine Idle Speed

The TCM uses direct engine idle speed input and calculated engine idle speed (or target idle speed) input from the PCM over the CCD Bus. Target idle speed is compared against actual engine speed to determine the learned Throttle Position Sensor (TPS) value for closed-throttle idle.

Throttle Position Sensor

The Throttle Position Sensor (TPS) is used by the TCM to help determine shift points and shift quality. Additionally, the TPS output is spliced to the PCM for fuel control. The PCM provides a 5 volt supply and ground for the sensor. Target idle speed is compared against actual engine speed to determine the learned TPS value for closed throttle idle. This is done to correct for differences in system voltage and sensor tolerances.

If the TCM detects a faulty TPS signal, it provides continued operation of the transaxle by using the TPS value sent over the communications bus by the PCM.

Just had transmission rebuilt and the speedometer bounces when in gear. Or with foot on brake. It bounces more with lights and a/c heat blower on.


You may want to have the place that rebuilt your transmission take a second look. It would also be a good idea to have the TCM codes scanned.

ELECTRONIC PINION FACTOR

The transmission output speed signal supplies distance pulses to the powertrain control module (PCM), which are used to calculate speed and mileage. A pinion factor is stored in the transmission control module (TCM) in order to provide the appropriate distance pulses for the vehicle. The pinion factor is programmed into the TCM at the assembly plant.

Using the following steps, the pinion factor can be checked and/or reset using the DRBIII®:

  • Select Transmission system, then Miscellaneous functions, then Pinion Factor. The DRBIII® will display the current tire size.
  • If the tire size is incorrect, depress the Enter key and then select the correct size.
  • Depress the Page Back key to exit the reset procedure.

Notes About Electronic Pinion Factor Features The nature of the electronic pinion factor requires that certain features must be taken into consideration.

  • If no pinion factor is stored in an installed TCM, the vehicle speedometer will not operate, engine speed will be limited to 2300 RPM, and catalyst damage may occur.
  • Selecting a wrong FDR or tire size will cause the speedometer to be inaccurate and will also cause any speed related features to operate improperly. Note: After replacing the TCM, you must reprogram pinion factor

2004 Chrysler Concorde

2004 Chrysler Concorde 2.7 recently developed code p0700 a general tranny code and p1779 solenoid switch in the l/r position. Did some looking and found a bare wire on either the speed input sensor or output sensor. Not sure what on. I fixed the problem and now the cruise control works as well. Could that have caused the tranny codes?


Yes.

2008 Chrysler Sebring

Originally, I had a code stating, out of time, crankshaft position sensor, and camshaft position sensor(total of 3). I changed the crankshaft sensor and cleared codes. ran car for 15 min. or so, light came on, camshaft sensor. I changed that, and now as soon as I start the car that po340 pops up instantly. does not say out of time anymore though. If I remember right earlier my reader said cam sensor slow response, then I installed a new sensor. Any ideas?


Chrysler Code P0340


DTC Code: P0340

Probable Causes:
  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage

Wheel moves sideways

When I lift the front wheel up, I noticed that the wheel moves sideways. What do you think would be the cause of this? My car is a 2004 Chrysler Concorde.


First of all, checking to see if the wheels move sideways is a test that is performed to check for hub bearing failure. This sideways motion is an indication of hub bearing failure. You will need to have this repaired sooner than later. Seems like you would have heard some noise as well. Must be why you decided to inspect the front end. As a result it turned out to be a good thing you did. Probably not what you wanted to find. So at least now you know what needs to be replaced. Furthermore I have provided you with the part you need and the instructions on how to do it yourself if you have the tools.

Hub Bearing Description

The front wheel bearing and front wheel hub of this vehicle are a hub and bearing unit type assembly. This unit combines the front wheel mounting hub (flange) and the front wheel bearing into a sealed one piece unit. Since they are one unit, they are commonly referred to as the hub bearing. The hub bearing is mounted to the center of the steering knuckle and is retained by three mounting bolts accessible from the rear of the steering knuckle. The hub flange has five wheel mounting studs.

The wheel mounting studs used to mount the tire and wheel to the vehicle are the only replaceable components of the hub bearing assembly. Therefore, the hub bearing is serviced only as a complete assembly.

Hub Bearing Operation

The hub and bearing has internal bearings that allow the hub to rotate with the driveshaft and tire and wheel. The five wheel mounting studs mount the tire and wheel, and brake rotor to the vehicle.
