rear axle seal leak

Hi all,

Hope you are doing well;

Guys need your inputs on issue which am facing it in my car ... first of all let me give you a brief idea about my Jeep,

Rubicon 2014 2 doors
lifted 2.5 inch
gear ratio ; 5.13
Auto transmission
Tuned via bully dog.

I went to pick my car from the service the technical guy said everything is perfect except the rear excel seal is leaking . Try to replace the seal and check if issue resolved if not then you have to change the excel along with shaft . i asked him why this happen he said that because of fixing a big tire 35 inch and this is 2nd rubicon with same issue . anyway i took the car to a another garage where i fixed all those item on my car and told him what service center guy told me .. he checked excel and confirmed that there is a leak left rear excel .. he said we have to replace the seal with baring but keep it in your mind that maybe this issue will come again because of gear ratio you have installed 5.13 and it is very fast ratio on 35 tires the best thing is to downgrade it to 4.56 gear ration ...

So please this my full story with my Rubi i need your inputs and help what shall i do .. shall i downgrade the gear ration or there is any other way to solve this problem. Also he said i will grantee you that you will not face this issue after downgrading the gear ration to 4.56 ..

waiting for your inputs

Thanks In Advance

Excel=axle I presume
I would highly doubt the ratio had anything to do with an axle seal leak. The axle itself could possibly be damaged, but it should be removed and inspected to be sure.

I call 100% B.S. yes low gears can create higher pressures in the housing, but thats why it is vented.
I'm here to participate. I didnt come all this way just to watch.

We've had both sides of our rear axle leak. 2012 JKU Sport with Sahara wheels. They have had to replace the axle on passenger side and still have to fix the driver's side. I call BS on the gear ratio also. The axle would still spin the same speed with a different gear ratio and same size tires. Only thing that goes faster is the pinion gear but that's not what is leaking.

It seems to me replacing the Excel seals without downgrading the gear ratio ... i felt that the mechanical guy is forcing me to downgrade .. anyways thanks for you feedback and comments it really helped me.

As long as the vent tube on the axle is not plugged the gear ratio will not cause an increase in axle pressure over what it is stock--so I am not buying that one. What is more likely is when they pulled the axle to change the gear ratio either the seal was nicked or damaged then. Did they replace the seals when they changed the axles or just pull the axles out so the carrier could be removed--that would be my question.

They removed and fixed the pinion after that they return back the excel and seal .. so maybe it not fixed properly.
