'99 volvo sx :Just been informed that my u-joint bellows was found to have gear lube inside due to a faulty yoke seal. They said the yoke was cracked and a replacement was around $400. Is that a fairly accurate price? Having been extremely careful with this outdrive (idle rpm's only when outdrive had to lifted for shallow water). No undue stress was ever put on the unit. I was very surprised this has occurred. Any thoughts on this or questions I should have with this diagnosis? Any attention to this would be appreciated. captpgn
