How do I replace rear axel seal ?

Who did the diagnosis and how did they explain it is related to the ABS light? You may need the repair but it may not fix the concern if it is unrelated. Let us know! Greg

If the axle seal is leaking the rear differential cover will need to be removed before the axle can be removed to access the seal. If this has rear disc brakes it will require removing the rear brake caliper and mounting hardware. Good luck

check the abs sens. on top of the rear axle
