Hi Nick,
The stop leak additives don't work if the seal is worn out or cracked.
Using grease instead of oil in a transaxle isn't usually recommended.
Gear oil is designed to flow freely and provide lubrication over a wide range of temperatures and operating conditions. It also contains additives that help protect gears and reduce wear. Steering box grease is thicker and does not flow as freely, which can lead to inadequate lubrication.
Gear oil has better heat dissipation properties compared to grease. Grease can trap heat within the gearbox, potentially leading to overheating and failure of components over time.
Gearboxes are designed to work with lubricants that minimize friction and allow parts to move smoothly. Grease can hinder the movement of gears, potentially causing them to bind or operate less efficiently.
Manufacturers specify particular lubricants for a reason—typically based on extensive testing to ensure optimal performance and longevity of the equipment. Deviating from these recommendations could lead to mechanical problems.
Grease is often used in steering boxes because they typically involve slower-moving parts and operate under different conditions than high-speed gearboxes.
Steering mechanisms generally involve slower, more controlled movement, which allows grease to provide effective lubrication without the need for the free-flowing properties of oil.
For longevity it's recommended to replace the oil seal . If you took the transaxle out and gave it to a repairer to
remove the wheels and change the seal it may not be that expensive .
Cheers
Max.
