Make sure you don't overfill the hubs. First time I did mine I filled them up at the 12 o'clock position and forgot to drain some at the 4 o'lock

 

I don't know the 700 but our 500s have a zerk on the steering post and the front drive shaft by the foot well, both very hard to find unless you know they are there. I use Mobil 1 and a Fram oil filter, have stayed with the Polaris air filter and gear oils.

 

The 700s where the first Polaris ATVs to get the centralized Hillary in the front diff. The AWD fluid goes in the front diff not gear oil like the rear diff,nothing goes into the front hubs.. Even my Friend's 03 700 has the centralized awd system.

550hr with only 2500 miles means the ATV does did alot of slow riding. I average 1000 miles to ever 100 hrs thats only 10 mph on average.
