Review on 🔧 DRIVESTAR 21-120 Power Steering Pump for Mercedes-Benz GL450 4.6L 4.7L, GL550 5.5L, ML350 3.0L 3.5L, ML550 5.5L, R350 3.5L, CL550, E350, E550, S550, CLS550 - High-Quality New OE Power Steering Pump by Kris Martin

This pump was a bit noisy from the start but after 6 months it broke down. I have no choice but to run around trying to get a replacement under warranty. They questioned the installation. Has the system been flushed? did you bleed the system? Etc. I explained that I was flushing the system! I have bled the system. I have done everything an ASE Certified Master would do because I am ONE! I tried calling her today. BUT. Phones don't receive calls there. Come on people! Replace defective pump!.
