lots of prowler seams to be suffering from leaking diff seals(like 3 out of 5 in our gang)
my question to the guys who delt with this issue

do you use ac factory seals or aftermarket seals :confused:

to tell you the truth out of 5 prowler with less than 300 miles that me and my buddies own we have 3 that have leaking seals

i thought that this was a common issue

i guess that if there is not enough oil it will heat the seal so that is why it leaks

I have had the best luck running mine 1 inch down from the bottom of the filler hole. I filled mine up to the bottom of the filler hole once after the first diff service I did. The seals leaked and the belows leaked. Ever since then 1 inch below for me. Pretty sure that is what the manual calls for too. These diffs run pretty warm so I am guessing they need the extra room for expansion of the fluid. I also put a real breather on mine front and rear just cause of the higher speeds mine usually sees when it is running. I will try to post some pics of the breather setup. If you do some searches there are already some topics on this stuff.

was just reading older post about it since you are an older member and the the cat is at the dealer, do you know if the did something on the newer models (2010) to fix the venting?

when it will be back from the shop i will check the level of fluid into both diffs and will call my buddies to let them know about that

To my knowledge they did not change the venting in 2010. Ask your dealer how full the rear diff should be. Here is something to think about. I am assuming the front diff is fine and the seals are not leaking? If so the point I wanted to make is that the rear diff does all of the work in 2wd. But the front diff has the same seals,fluid, bellows etc. But it is the rear one that is leaking right? What I believe is that the warm fluid expansion is so great that it makes pressure that the bellows just can't relieve. So the weakest link next is the seal. Another theory is that the rear diff gets warm and the fluid thins out somewhat. Then from the pressure it goes right past the seals.
The front diff does not have load on it in 2wd so it does not run as warm.

this is my solution to this problem, 2 glass gas filters 2 air filters and some hose , you have to relocate the front diff breather and don't use the original bellow you can trow that one to the garbage, the rear diff breather is height enough so on this one just take off the bellow and replace whit the gas and air filter combo , this was my solution to this problem and i don't have any leaking. the glass filter act like a reserve tank for the oil, and believe me the oil make his way to this filter, and the air filter act as a breather so you are not going to have any oil pressure and you are not going to have any leaking also ...

we only run 9 oz. in the diff's. i think the book calls for 12 or so, but at 12 it will expand and blow the seals, when my 650 was 1 week old it split the bellows from the pressure. drained it out, put 9 oz. in and never had an issue. sold it with 1000 miles on it. i would also look for a groove cut into the axle cup. and while your there kock the dust sheild off, they seem to hold sand and mud against the seal.

Oh that is different. If you have a axle popping out either front or back you are gonna have contaminants involved. Like dirt mud etc. You cannot just pop it back in and it not leak. At a minimum imo the fluid has to be cleaned off. And I don't know if I would want to reuse the old seal now. I am sure the seal has had to put up with the axle flopping around some cause it is not seated.
The xtz's had a problem with the rears for awhile and they came up with a trick new axle to solve it. This is the first I have heard or can remember a front axle popping out.
