I need to replace the rear differential in my 2006 500 TRV. I see several of them on eBay and they all look basically the same. Are they all the gear ratios? There’s a pretty drastic price ranging from 100 bucks to 400. Can someone explain the differences. This is the tag on the side of my diff, do I have to buy one with the exact same numbers or are they interchangeable?
Thanks

For the most part 2005-2009 are the years you want as you have 3.6 gears. 2009 and up to 2013 only the 550 , and 400trv used the 3.6 gears. Everything else went to 3.1 gears.
The only differences in those years are the nose cone. Just use the nose cone off your diff. And get the right gear ratio.
