My advice is...change it now!
I bought my tour last feb. (with 85K) and during the summer found out the hard way that the ABS didn't work (didn't break anything luckely), anyway took it to Ford and the ABS pump is shot, you gussed it, bad fluid. Turns out that a new pump is something like 1500
(canadian). Needless to say I won't be tailgating
Do it now, before its too late.
