I've wondered about this suspension fluid. During routine 60,000 mile scheduled maintenance on my 2002 LX, my Lexus dealer told me that the suspension fluid needed to be replaced. I got a price from a local repair shop that I used to take my Landcruiser to for half the price of what Lexus was going to charge me for the fluid flush. When I went to go pick up the vehicle, I asked the mechanic if he could tell or see any difference between the old fluid and the new. He claimed that there was no visible difference in the fluids appearance, smell or touch. Of course he's not a Lexus dealer either, but it makes me a little suspicious. Is it reasonable to assume that the fluid would begin to break down at 60,000 miles?
