Replaced steering rack at 25K miles??

[Boston X5 4.4]

I have been having problems with some noises in the steering when the X is stationary. Seems similar but not identical to some problems others have had here.
Local stealership replaced the steering rack and assembly and the car drives like new, very tight steering. I have 25K on the X - don't you think that this is way to early for the steering to go?

I had some other stuff done at the same time - glad I am still under warranty or the whole trip to the dealership would have cost almost $3,500 - 4,000

~ $1,800 for new rack
+ 4 wheel alignment
+ front and rear pads, rotors, sensors
+ new rear taillight assemblies (kept getting check brake light message)
= ~ $4K
