Hi guys, my brother has an 04 Maxima he bought it of the show room when it was brand new,and now it got 75k. The ABS acting up lately making noise when using brakes and ABS actuator stay running constantly so it will kill the battery over night, also ABS and brake light on. He took it to the dealer and they told him that the ABS pump actuator is no good, it would cost him $1700 for the part and labor. I wanted to help out my brother so i ordered i used pump and installed in the car, now there is no more ABS or brake light on dash, no more whining noise from ABS pump and it's not draining the battery when the car is turn off but when using the brakes, the ABS noise still there so i need your help.
All the speed sensors are working according to my scanner, i took both rear hubs out and clean the rust off, there is no ABS codes at all.

 

Nevermind i got it fixed. Thank you for reading.
I changed the RR wheel bearing and that took care of the ABS noises. (I tried clean both rear hub bearings and sensors before that but it didn't work)
