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.
The most likely cause is a defective or worn outer CV axle joint. It may be time to get it replaced.
The most likely cause is the drive train shifting in the chassis due to a broken engine mount or hardware, causing misalignment of the axle and causing the inner joint to bind or hang up.
The most likely problem is the outer CV boot has ruptured, causing the grease to leak out, allowing contamination (water and dirt) to enter and damage the joint.
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 axle at a time when replacing the drive axles.
NO! Prevailing type lock nuts should never be reused. Always discard old and install a new one.
Always use the proper press type tool to remove the old shaft. NEVER strike the outer stub shaft with a hammer. It will damage the unit and possibly do damage to the hub bearing assembly.
Never use an impact wrench to install the nut on the axle. Always use a torque wrench and torque the nut to manufacture's specifications.
When replacing axle assemblies, always install new transaxle seals.
Never allow the CV shafts to hang unsupported. This can lead to axle separation and damage to the inner joint.
The most likely cause is a broken bearing cage due to excessive torque load. Typically this in an outboard joint problem.
