How To Replace CV Axle

CV Axle Replacement


Step by step instruction on how to replace a CV joint drive axle. This article pertains to most front wheel drive cars with strut suspension.
Difficulty Scale Rating: 5 of 10
Tools and Supplies Needed
  • Hydraulic jack
  • Jack stands
  • Socket set with extensions
  • Protective clothing and eyewear
  • Replacement axle
  • Hammer
  • Breaker bar
  • Large pry bar
  • Side cutters (dikes)
  • Cotter pin
Start with the car on level ground lifted safety into the air using jack stands to secure the vehicle.
Step 1 - Remove tire lug nuts to remove the wheel. If air tools are not not used break loose the lugs when the car is on the ground.

Loosening Lug Nuts
Step 2 - After the wheel lugs have been removed the tire is ready to be removed. 

Removing Tire
Step 3 - Once the tire has been removed, it will allow access to the main axle nut, remove the cotter pin and retainer clip.

Removing Cotter Pin
Step 4 - After the cotter pin has been removed, loosen and remove the main axle nut. (Note: If no air tools are used this can be done by using the brake.)

Removing the Main Axle Nut

Step 5 - Once the nut has been removed the axle will become free within the bearing hub.

Step 6 - Next, remove the cotter pin used in the lower ball joint.

Step 7 - Once the cotter pin has been removed, use a wrench to loosen the lower ball joint nut.

Loosening Lower Ball Joint Nut

Step 8 - Leave the lower ball joint nut loose to help protect the threads which is needed in the next step.

Step 9 - Using a large pry bar apply pressure downward while shocking the bulkhead with a hammer.

Step 10 - When the ball joint taper joint releases there will be a noticeable gap between the ball joint dust boot and the spindle.

Step 11 - Once the ball joint taper fit has been released, finish removing the nut.

Removing Lower Ball Joint Nut
Step 12 - After the lower control arm nut has been removed, apply pressure downward to remove the lower control arm.

Step 13 - Next, remove the intermediate mounting bolts, some cars do not use this mount, in which case a large pry bar is used to pop the CV joint out from the transmission.

Removing Intermediate Mounting Bolts

Step 14 - Then, while pulling outward on the brake rotor, tap the axle out of the bearing hub. (Note: Use caution as to not damage axle treads, the axle nut can be used to achieve this protection.)

Gently Tap Axle
Step 15 - After the axle is loose from the bearing hub, hold the brake assembly to remove the CV axle.

Holding Brake Assembly Outward
Step 16 - After the old axle has been removed, match the replacement axle to the old axle to ensure proper installation.

how to replace Throttle position sensor on 2000 ford expedition

Image
Ford TPS Sensor Replacement Throttle Position Sensor The Throttle Position (TP) sensor is a potentiometer that provides a signal to the PCM that is directly proportional to the throttle plate position. The TP sensor is mounted on the side of the throttle body and is connected to the throttle plate shaft. The TP sensor monitors throttle plate movement and position, and transmits an appropriate electrical signal to the PCM. These signals are used by the PCM to adjust the air/fuel mixture, spark timing and EGR operation according to engine load at idle, part throttle, or full throttle. The TP sensor is not adjustable. The TP sensor receives a 5 volt reference signal and a ground circuit from the PCM. A return signal circuit is connected to a wiper that runs on a resistor internally on the sensor. The further the throttle is opened, the wiper moves along the resistor, at wide open throttle, the wiper essentially creates a loop between the reference signal and the signal return ret...

Ford TFI-IV System Details And Diagrams

Ford Engine TFI-IV System GENERAL INFORMATION See Figures 1 and 2 Fig. Fig. 1: TFI schematic Fig. Fig. 2: Exploded view of the TFI components The Thick Film Integrated (TFI-IV) ignition system uses a camshaft driven distributor with no centrifugal or vacuum advance. The distributor has a diecast base, incorporating a Hall effect stator assembly. The TFI-IV system module is mounted on the distributor base, it has 6 pins and uses an E-Core ignition coil, named after the shape of the laminations making up the core. The TFI-IV module supplies voltage to the Profile Ignition Pick-up (PIP) sensor, which sends the crankshaft position information to the TFI-IV module. The TFI-IV module then sends this information to the EEC-IV module, which determines the spark timing and sends an electronic signal to the TFI-IV ignition module to turn off the coil and produce a spark to fire the spark plug. The operation of the universal distributor is accomplished through the H...
