    To give you an idea a B-Level Tech (basic) should be able to do it in 2.3 hours mechanic flat rate book time… I do not know your skill level, but this is not a simple fix and does require some skill level...

    Removal and Installation:
    1. CAUTION: Do not allow any metal object to come in contact with the generator housing and internal diode cooling fins. A short circuit may result and burn out the diodes.
    Disconnect the battery.
    2. Remove the RH intermediate axle shaft.
    3. Remove the 6 lower splash shield bolts and the 2 pin-type retainers.
    • To install, tighten to 8 Nm (71 lb-in) .
    4. NOTE: The LH lower splash shield must be removed before the RH lower splash shield.
    Remove the lower splash shields.
    5. Remove the nut and position the bracket and wiring harness aside.
    6. Rotate the front end accessory drive tensioner counterclockwise and position the accessory drive belt aside.

    • To install, tighten to 4 Nm (35 lb-in) .
    10. Loosen the 2 lower generator bolts and remove the generator lower air duct.
    11. Remove the pin-type retainer from the generator shield.
    12. Remove the bolt and the generator shield.
    • To install, tighten to 4 Nm (35 lb-in) .
    13. Remove the generator stud nut.
    • To install, tighten to 47 Nm (35 lb-ft) .
    14. Remove the generator stud.
    • To install, tighten to 7 Nm (62 lb-in) .
    15. Remove the 2 generator bolts.

    17. Remove the generator upper air duct.
    18. Rotate the generator to gain enough clearance and remove it through the opening in the fender well.
    19. If necessary, remove the 2 generator bracket bolts and the generator bracket.

    Incredibly difficult. Sell the vehicle. It is not worth it. Brake lines have to be moved. The strut has to be moved. The CV axle has to be removed. The tie rod end has to be moved if you plan on removing the bolts that hold the alternator in. And then...you have to remove the alternator. It can only be done left handed, and you cannot see what you are doing. Unless you can see through (2) layers of solid steel. Rebuilding the transmission is easier and faster.
