My Toyota Yaris T3 D-4D, purchased new in July 2003, has now covered 37,300 miles. It has developed a ticking noise when on full lock which a Toyota main dealer has diagnosed as driveshaft wear. They have quoted me £1,112.31 for removing and installing new shafts and outer joints, and fitting the old inner joints onto the new shafts. Is replacement at this mileage and the shockingly high cost reasonable or should I seek a contribution from Toyota? Is there a cheaper option available?
