My 1999 Avalon has 160K miles and is paid for. All 4 tires were recently replaced and have performed well thanx to a minimum of 2 recent FEAs at a local garage. However it began drifting to the right and the tires had not been rotated for a while so it was taken to a national tire chain for a “BAR” (balance, align and rotate) for the first of 4 visits. On visit #1 the “tech” only recommended monitoring the brakes since the pads were thin. After the “BAR” the car drifted left and shimmied which it had not done before. Visit # 2 another “tech” insisted that a new inner tie rod would correct both problems. I agreed to the replacement but now the car now pulled SHARPLY to the left. On visit #3 the service manager inspected and claimed that a power steering pump and rack & pinion were needed to correct ($940) - no replacements were made but the tires were re-rotated to their original positions. The shimmy was reduced but not completely eliminated and it continued to pull sharply to the left. On visit #4 the tires were dis-mounted, reversed and re-mounted on opposite side but the sharp pull to the left remains. What shd i do now ? Any reasonable suggestions will be greatly appreciated.
