Here is what you are saying in this thread….

-Changing gear oil makes little difference

-New bevel box is no guarantee of improvement…maybe 50/50 chance at best

-3 Point Classic in Brisbane has performed 2 lap jobs on 2 bevel boxes successfully.
The cost was $1300 including r&r as per Trevor V

My desire is to find someone who can fix the noise issue. Then one by one we can send them our units to put right. I am not looking for a magic bullet but a reliable and noticeable improvement!

Can Trevor V or anyone else weigh in on a recommendation or references of 3 Point Classic? Do they need to replace the ring and pinion as part of the service. How much does mileage matter. I am at 1300 miles (my second one) and the noise is steadily increasing.

I need more info before taking the next step. Let's keep this going and together we can find a solution.
