first of all on the left side of the diff there is a rubber or plastic ring around the axle right next to the diff, it appears to be leaking around it, and I can wiggle it abit, what should i do? also just changed the differential fluid yesterday with abit more than 8oz. secondly I can grab the whole differential and wiggle it also is that normal?

Sounds like your talking about the CV boot, if it is cracked or torn then replace it. If it is just leaking grease out the ends you may just need new band clamps on it.

It is not normal to wriggle the diff, tighten it down.

I put 8oz in the rear diff and then I poured some more in it then after riding today I noticed the leaking, and I just noticed it seems leaking at the front of the rear diff too, maybe I ruptured the seals?

There is a dust cover in the end of the axle and they get loose. Behind that is a diff seal and it is very common when you put more than 8-8.5 oz in for them to start leaking. It's an easy job to change them and there are a couple write ups in the pinned section.
^^^agreed your diff should not move

how much should I have put in the rear diff? are there just a few bolts holding the diff down?

There's only 2 and 8 oz is the accepted amount. I always pack the back side of the seal and cavity with red and tacky grease and mine never leak anymore

Welcome to the wonderful world of Arctic Cat differentials.

If you want them to NOT leak you have a few options:
1. Replace them every 2-4 weeks, or after every 3-4 rides.
2. drain fluid after every ride and refill before the next one.
3. Fill them with grease
4. Sell your Arctic Cat


I'm fond of option 3 and 4 myself. But number 1 is usually what I have to go with.


all jokes aside, doorfx had the best advice. I put red and tacky behind my seals, but still have to replace them monthly (or just drain and refill after/before very ride). Their are updated seals, but they honestly don't seem much better in my experience.

I'm not sure if some of the housings are out round or what. The exact opposite has been my experience. I replaced them and have never had a leak again. Very happy
