BILL J. - If you can stand the noise, I think I'd keep the spindles greased and run them as long as you can. My old 44A deck was noisy too, and I ran it 15 yrs. As long as the spindles hold the blade securely, so you can't wiggle the blade tips up & down, the deck will mow just fine. I had a bad spindle on my 50C, the bearing was loose in the housing, and it cost $170 for both halfs of the housing and a new spindle... plus $1 for the new Woodruff key. OUCH! But fixing that bad spindle sure made it mow nice.
