Is it hard to replace alternator? I heard that you take right wheel off to get to it?

On this car some alternators are at the top some are at the bottom depending on the engine. You can't get at it thru the wheel well but you can get them from the top of the engine compartment ,or from under the car. The main thing to remember is that after you remove the serpentine belt the alternator is removed by turning the pulley in order to get your wrench thru the holes in the pulley, and onto the holding bolts. I have heard to many stories of the plastic pulley's being broken because wrenches were forced in behind the pulley's. The other wires can easily be removed. Remember disconnect your battery.Please let me know if I've helped you ,and don't forget to vote. GOOD LUCK .

Water pump frozed and took the belt out lost alternator lost power steering. youll have to two it for repair. hopefully it was just a belt.

Hi, yes, this is a pretty big job but not really hard. You have to jack up the car and go in through the wheel well to get the alternator out. Fortunately, there are good instructions at autozone.com, which I have pasted below. Please let me know if you have any questions and thanks for using FixYa.

REMOVAL & INSTALLATION See Figures 2 through 11

1. Disconnect the negative battery cable.
2. Remove the serpentine drive belt.
3. Raise and support the vehicle safely.
4. Remove the right front wheel from the vehicle.
5. Remove the right wheel inner fender splash shield.
6. If equipped, remove the alternator dust shield attaching bolt and unclip the shield from the alternator. When removing the dust shield, be careful not to damage the rubber boot over the battery's positive terminal.
7. Disengage the alternator field wire connector.
8. Remove the retaining nut and wire from the positive (B+) terminal on the back of the alternator, using alternator output stud wrench SA9401C or equivalent, as a back-up wrench to prevent the stud from rotating. If the positive terminal stud rotates, the plastic insulator will crack or break, causing alternator failure.
9. Remove the upper and lower alternator attaching bolts.
10. Remove the alternator from the vehicle through the wheel well opening.

To install:

1. Position the alternator in the vehicle and install the lower attaching bolt.
2. Install the upper attaching bolt and tighten both bolts to 24 ft. lbs. (32 Nm).
3. Engage the alternator field wire connector.
4. Install the B+ terminal wire. The battery terminal wire should be placed on the back of the alternator between a 10 and 11 o'clock position.
5. Be sure to use the alternator output stud wrench SA9401C to prevent the terminal stud from rotating, then tighten the alternator positive terminal nut to 89 inch lbs. (10 Nm).
6. Install the alternator dust shield and tighten the fastener bolt to 89 inch lbs. (10 Nm).
7. Install the serpentine drive belt.
8. Install the wheel well splash shield and right front wheel. Tighten the wheel lugs in a criss-cross pattern to 103 ft. lbs. (140 Nm).
9. Remove the supports and lower the vehicle.
10. Connect the negative battery cable.

sounds like eithor your belt broke or you broke a power steering line see if leaking power steering fluid

Remove or disconnect the following:

• Negative battery cable
  
• Right front wheel
  
• Right fender splash shield
  
• Accessory drive belt
  

NOTE The crankshaft pulley retainer has left-hand threads.

• Crankshaft pulley
  
• Alternator harness connectors
  
• Alternator
  

Remove the crankshaft pulley to provide clearance—2002–04 3.0L


To install:

1. Install or connect the following:
   
   • Alternator and tighten the fasteners to 18 ft. lbs. (25 Nm)
     
   • Alternator harness connectors
     
   NOTE The crankshaft pulley retainer has left-hand threads.
   
   
   • Crankshaft pulley and tighten to 74 ft. lbs. (100 Nm)
     
   • Accessory drive belt
     
   • Right fender splash shield
     
   • Right front wheel
     
   • Negative battery cable
     
2. Start the engine and check for proper operation
   

*Check wheel bolts are tight*

Could be one of these

Lose wheel
Worn / faulty outer ball joint
Wheel alignment
Steering angle sensor
Tyre pressure

Those are the most likely but the list can go on more

The location can best be seen by reading the replacement procedures. It is well hidden behind the right front wheel's splash shield. If you plan on replacing it yourself; You'll have the instructions.

Disconnect the negative battery cable...Remove the serpentine drive belt, use a wrench on the tension pulley to remove belt...Raise and support the vehicle...Remove the right front wheel...Remove the right wheel splash shield; it is two parts...Remove the alternator dust shield; it is attached with one bolt and one clip...Remove the two sets of wires from the alternator; one has a clip to connect it to the alternator and one is bolted to the alternator; be very gentle with the bolted one so you do not break the plastic insulator (especially during re-installation)...remove the upper and lower attaching bolts from the alternator; the top boltis easyto get to from the top of the engine, the bolt is just below the power steering unit...remove alternator through the wheel well opening...To re-install follow the steps in reverse.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

ok you have a bad right front wheel bearing by what you are describing

disassemble the right wheel assembly and pull out the right wheel axel. Remove the alternator throught the right wheel well.

Oxygen sensor might be faulty, as it causes the light to come on, but injectors hardly causes the light to come on, alternator( battery) light is an indication that the alternator needs to be replaced.
