Easy Alternator Change

At a little over 85,000 miles on my '06 it developed a very high alternator whine coming through the sound/intercom system. Shortly after that the volt meter started bouncing around quite a bit. My research and troubleshooting led me to believe it was the alternator. I ordered the part from HDL and researched the board on options for replacing the alternator without removing the fuel tank. I found the posts which explained how to take the alternator out by removing the battery and battery box and using different length socket extensions to get to the inside mounting bolt, and the post suggesting removing the rear wheel to get at it. Well, after looking at the location of the bolt and experimenting a little I found a way to replace the alternatator without removing the battery or the rear wheel. Knowing what I do now, I can replace an alternator in about 20 minutes.
Here is what I did:
-Disconnect the + cable from the battery just for safety.
-Remove the side cover to gain access to the alternator.
-Disconnect the wires from the rear of the alternator. (This will provide the needed clearance to be able to loosen the inside bolt.
-Remove the two accessable bolts with a regular box end wrench.
-Here is what I used to get to the inside bolt.



I was able to slide it in behind the alternator and swivel the socket and extension to line up with the inside bolt.



As you can see after removing the wires from the rear of the alternator, there is enough room to rotate the wrench handle down to loosen the bolt.



I used one of the telescoping pen magnets to help line up the socket with the bolt and once I loosened the bolt I was able to use the telescoping pen magnet to unscrew the bolt by just repeatedly rolling the magnet over the top of the bolt head.



I could not believe how easy it was to do.

I hope I explained this well enough so that it will help someone else.

Thanks for the tip ...but did your whine go away after replacing the alternator? I have a whine I hear through the speakers but not the intercom. I done all the regular "fixes" but it's still there.

That magnet "trick" is TRICK!!!

I changed an alternator last week and I ended up going through the rear wheel area with a number of extensions to take out that stupid bolt.

Next time, I'll know better!

Good job, I copied it and stored it away for a rainy day, hopefully it doesn't rain for a long while.

On Edit: How hard was it to get that rear bolt back in?
