Yep, changed mine 2 years ago at 115K, now I have 125ish. I also change my oil twice a year, and the diff oil once a year. Tranny every once in awhile. I figure I should be good for 5 years or so.
Now the power steering fluid, I got one of those power steering filters on ebay, worked like a champ...lol.
I don't mess with the power steering at all, a newpump is like 50 bucks, cost more in time and fluid to change the fluid every few years than to just wait until the pump dies.
