Good Morning:
I have read through countless threads on Volvo steering problems, but I have not yet figured out how to fix my problem. I have a 2004 boat with a Volvo 5.7 Gxi-F engine, a TSK SX MHP transom assembly, and a DPSM 1.95 lower unit. The steering has develop a vibration in both directions. The vibration is only present when actually steering, and it gets worse the more I turn to each side. Initially, I checked the pump and noticed that the fluid was low, so I added fluid and went through the steps required to bleed any air. I tend to be inpatient, and I'm not sure if I actually turned the wheel over enough times to bleed the system properly, but the vibration went away. After about 2 hours of use, the vibration returned. I checked the pump and noticed that I over-filled the power steering, so I removed fluid to the COLD mark and again bled the unit. This time, the vibration did not go away. I hauled the boat and started working on the boat in my driveway. With the engine off, my son steered to each side as I inspected the lower unit from below the boat. The vibration was very loud as he steered from side to side. I then attached a hose to my lower unit, started the engine, and has my son steer from side to side once again: same vibration. We went through a bleeding procedure with the engine "cold," and then re-started the engine and did the same procedure (stop to stop over and over), with no change. I decided to apply grease to the steering cylinder (the upper, machined cylinder in the picture below), and the vibration went away. However, after steering from side to side 5-6 times, the vibration returned. Any ideas or suggestions would be appreciated. Thank you.
