Follow-up on my origninal posting. Dealer said it would cost close to $800.00 to replace 2 lines! The parts guy unofficially suggested I just take off the X-REAS and replace it with 4 shocks. The dealer had no intention of helping me with this matter since the vehicle was out of warranty. I called Corporate Toyota, and they could not care less about it. Sad to say I had a similar experience with Ford a few years ago and that was my last Ford.
So, I bought 4 Bilstein Shocks from shox.com for $289 and took off the X-REAS. The fronts were tricky to replace, and I cut the top studs off the rears to get them off. The car handles fine, and I am glad to be done with this issue! BTW, the guy at Shox.com was very helpful and I got the shocks right away. I definitely recommend them! I hope this is helpful.
