Hope this help (remember comment and rated this).

I have the '93 shop manual which describes how to do it with the 3.3L and I have the Haynes that covers the 3.3/3.8L for '96-99 and they read about the same. Let me give you the one from the '93 Chrysler shop manual:
1.Disconnect the battery.
2. Remove the alternator drive belt
3. Loosen, but do not remove, the nut on the support bracket at the exhaust manifold. (this is on the rear of the engine where the bracket is attached to one of the exhaust manifold studs).
4. Remove the alternator tensioner power steering bracket bolt.
5. Remove the tensioner stud nut and the tensioner.
6. Remove the 2 alternator mounting bolts.
7. Remove and position the power steering reservoir from the alternator mounting bracket. Do not remove the hose from the reservoir.
8. Remove the 3 alternator support bracket bolts.
9. Remove intake plenum-to-alternator mounting bracket bolt
10. Remove alternator support bracket.
11. Position alternator and remove alternator wiring.
12. Remove alternator!
Again this is for the 3.3L and is from the '93 van manual but it appears to apply to the 3.8L as well. Installation is the reverse, tighten the mounting bolts to 40 ft-lbs.

Good luck.

I have a 2001 Mazda Tribute. To change the alternator; the factory procedure at the dealership says to drop the sub-frame from under the front of the vehicle. Then everything is accessable. The tech at the dealership told me how they do it: (Its not easy!!) 1. Remove the right front tire 2. Remove dust pan from right front 3. Remove the brake caliper and caliper bracket 4. Remove the 2 bolts from the half shaft support bracket 5. Remove the half shaft axle assembly 6. Remove the serpentine belt 7. Remove the 3 bolts holding the alternator in place 8. Remove the 3 bolts holding the alternator mounting bracket 9. Remove the alternator mounting bracket 10. Remove the electrical connection on the alternator 11. Remove the alternator by turning the alternator until it will come out of the opening 12. Repeat process in reverse for installation. I did this twice in two weeks because of a bad alternator. The studs that are spot welded on the half shaft bracket will try to keep you from being able to remove the alternator. The left stud on the bracket popped out, when we were removing the alternator and it seemed to make it easier to get the alternator out. I just put a lock washer on the back side of the stud when I mounted the half shaft and it worked fine. Good luck
