Loosening Lug Nuts
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.
Axle Nut Removed Step 6 - Next, remove the cotter pin used in the lower ball joint.
Removing Ball Joint Cotter Pin 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.
Lose Lower Ball Joint Step 9 - Using a large pry bar apply pressure downward while shocking the bulkhead with a hammer.
Shocking Bulkhead Under Pressure With 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.
Ball Joint Taper Joint Released 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.
Removing 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.
Matching Replacement Axle Step 17 - Next, while holding the Brake assembly outward, install the new drive axle.
Installing New Drive Axle Step 18 - Once the axle has been installed into the transmission, install the outer CV joint into the bearing hub.
Installing Outer CV Joint Step 19 - Then, reinstall the intermediate bearing mounting bolts. If not equipped, the axle needs to be popped into the transmission with a forward thrusting motion.
Reinstalling Intermediate Bearing Bolts Step 20 - Once the axle has been reinstalled, install and tighten the lower ball joint nut.
Reinstalling Lower Ball Joint Step 21 - After the lower ball joint mounting bolt has been tightened, install a new cotter pin and secure
Installing New Cotter Pin Step 22 - Then, the lower ball joint mounting nut is in place and tight reinstall the outer axle nut and tighten.
Reinstalling Axle Nut Step 23 - Next, install a new cotter pin
Installing New Cotter Pin Once all pins are reinstalled, remount the tire and tighten lug nuts. When driving listen for any strange noises which would indicate there is a malfunction. Helpful Information Most front wheel drive vehicles utilize axles with CV joints. These axles are designed with a constant velocity (CV) joint at each end. The most common cause of failure is due to the CV boot fails allowing grease to leak out causing the joint to fail. When this occurs a clicking noise is generated when turning or accelerating. Best Practices
- Use new cotter pins upon reassembly
