FAQ_Q1 I installed a replacement CV drive axle and now my ABS light is on and won't go out. Why?
FAA_A1 When the replacement drive axle was installed, the sensor ring, sensor, or sensor wiring on or near the axle was damaged, causing an erratic speed signal to the ABS module and setting the light on.
FAQ_Q2 When I cut the wheel hard and step on the gas, I hear loud clicking and snapping. What's making that noise?
FAA_A2 The most likely cause is a defective or worn outer CV drive axle joint. It may be time to get it replaced.
FAQ_Q3 When I step on the gas, I hear a loud thump and feel a bad vibration. What's wrong?
FAA_A3 The most likely cause is the drive train shifting in the chassis due to a broken engine mount or hardware, causing misalignment of the CV drive axle and causing the inner joint to bind or hang up.
FAQ_Q4 I hear a grinding noise from the front end while driving and see grease on the chassis and suspension. What is causing this?
FAA_A4 The most likely problem is the outer CV drive axle boot has ruptured, causing the grease to leak out, allowing contamination (water and dirt) to enter and damage the joint.
FAQ_Q5 I removed both CV drive axles at the same time and now I am having problems reinstalling them. What can I do?
FAA_A5 The transaxle gear alignment has been lost. On some vehicles it will be necessary to disassemble the transaxle to properly align the output gears. ALWAYS remove and install one CV drive axle at a time.
FAQ_Q6 The old CV Drive Axle has a locking style (prevailing torque) nut. Should I reuse it?
FAA_A6 NO! A prevailing torque lock nut should never be reused. Always discard the old nut and install a new one.
FAQ_Q7 The CV Drive Axle outboard joint stub shaft is stuck in the hub assembly. What's the best way to remove it?
FAA_A7 Always use the proper press type tool to remove the old stub shaft. NEVER strike the outer joint stub shaft with a hammer. It will damage the unit and possibly do damage to the hub bearing assembly.
FAQ_Q8 Is it OK to use an impact hammer to install the retaining nut?
FAA_A8 Never use an impact wrench to install the retaining nut on the CV Drive Axle. Always use a torque wrench and torque the nut to manufacture's specifications.
FAQ_Q9 When I replace the CV drive axles, should I reuse the old seals?
FAA_A9 When replacing CV Drive Axle assemblies, always install new transaxle seals to avoid leaking.
FAQ_Q10 Can I let the CV Drive Axles hang while I am working on the car?
FAA_A10 Never allow the CV Drive Axles to hang unsupported. This can lead to axle separation and damage to the inner joint.
FAQ_Q11 The wheels wobble when I make a turn. What's the problem?
FAA_A11 The most likely cause is a broken bearing cage due to excessive torque load. This is typically an outboard joint problem.
