Gentlemen, this is what I found in my year 2014 file from Road Smith.....
Hi Bill,
Since your kit was produced in 2012 that would make your differential a Ford based product. There is a ¾” plug in the rear of the differential that isn’t exactly easy to get to but it is there. As long as there are no major leaks there really isn’t a need to check it however. It is filled with one full quart from the factory. The fluid level from the plug hole should be about one inch below the hole. The differential manufacturer recommends changing the fluid every 50K miles but that’s for normal automotive applications. Since this is on a trike with much less working stress than a car, you could easily go more than that without hurting anything. There is also a heavy magnet inside the diff that would catch any metal shavings before they’d get into the gears.
Hopefully this helps but as always feel free to let me know if you have any other questions.
Thanks!

I drove the trike about ten miles to warm up diff, removed the fill and drain plug and went to have lunch. When I came back I put a hand pump into the quart bottle of rear end oil and pumped it into the diff. Couldn't quite get all of it out of the bottle and up the pump's hose so a little less than a quart. Worked like a champ and no chance of over filling.
If you have diff that requires less, simply remove excess from bottle before pumping and get on with it. Again, no chance of overfilling.

I'm surprised NO ONE HAS EVEN MENTIONED the two grease jerk fittings just before the universal area.....
I just grease those yesterday, along with oil / filter, and spark plugs changed when putting bike away for the winter season.....

Hi Ronnie,
I believe I saw somewhere on this forum where RS says those only need a small shot about once/year. I think those are for greasing the splines in the drive shaft.
Thank you "everybody" I'm going to crawl under my bike once this dang weather warms up a bit, and see what I can find, and go ahead, and try that rear end fluid change....Can't see why I can't do it..... I usually find that everytime I'm abit worried about doing a job, I usually find that is wasn't that big of a DEAL, AND I WORRIED FOR NOTHING.. last week I replaced the Radiator fluid in the wing, I worried that I'd not be able to accomplish this job, well it was a piece of cake and I saved myself alot of money, and had hand prints on the back of my shirt, because I gave myself a pat on the back.... LOL

Thanks for the reply. I went back out, put it up on jack stands and pulled the tires off and took another look. It was on the right side, directly facing the tire.
