Can anyone see what's wrong here?

I see broken stuff....kids get into your tools? Nothing like your kid bringing you a piston and saying "hey dad, check this thing out"

I see two broken spider gears.  How did it happen?

I see two broken spider gears.   

And it's absolutely filthy. Think I'll go change mine again just for GP.

yep well done that man !! 2 broken spider gears .broke a bit too easily for my liking! heading up a trail in 4 wheel drive and landed the front wheel down not that hard and bang it broke. new parts ordered and will be cleaned and fixed and be kept as a spare,
could not get on the forum for the last 8 hours?said the site was down?

Terrible news. Post more pics of the rebuild if you can.

That's the second one I heard of breaking a front diff when jumping and landing on the front in 4wd. I guess this should be avoided...jumping in 4wd that is..lol

If the video loads up you can see and hear when it goes bang

F'k....Well, that'll do it.

I've been putting some pressure on SuperATV to get their Rhino Axle brand to include axles for the ZFoce 800 EX line up. I sent them another email today asking if they have them in the works. Lets hope so.

If not, maybe I can pass along their email and have the whole lot of us send in requests so they know theres a market for them.

And just thinking out loud, with the demand being up for lift kits, the need for a better axle and CV joint will go hand-in-hand...so it would be to their advantage to have that option for us. They don't necessarily have to keep them in stock but just be a place we can buy them through.

Would so like to see someone do uprated cvs and diffs ! Spoke to a couple of companies in the uk but they are not interested , all they want to do is Polaris upgrades , just ordered some larger tyres and beginning to think if it's a wise idea to fit them! Just been out and broken a rear cv now also!!

Rhino does make axles and CVs for these. Just need to find a distributer that will ship to the UK, US & Canada.

Have you a link to rhino products?

I'll see if I can find it again but for now Side-by-Side stuff has these and can get more made by Rugged. They are a better axle then the stocks.
