i replaced the whole pump unit with mine. the whine went away, and i used the lucas stuff. lately it has been doing the whine but only when im turning at low speeds, but i blame the bad weather for all this. id recommend putting that new one back on and ride if off. it says on the unit that its going to whine for awhile to break it in.
also, 90 percent lucas, rest regular power steering fluid. well, at least thats what i did and the whine and all went away. also that full turning 10+ times and all worked for me when i did it
