Frequently Asked Questions (FAQs)
1. Is differential leak serious?
Yes, a differential leak is a serious issue. The differential fluid lubricates the gears responsible for transferring power from the driveshaft to the wheel axle. If the fluid runs low due to a leak, it can cause significant damage to these gears, potentially affecting the performance and reliability of your vehicle.
2. Can I drive with a leaky differential?
In general, driving with a leaky differential won't make your vehicle unsafe in an emergency. However, it is important to address the leak as soon as possible. Insufficient differential fluid can lead to damage to the gears and impact the overall performance of your vehicle.
3. Is a gasket better than RTV?
Whether a gasket or RTV sealant is better depends on the specific application. RTV sealant is suitable for many applications, such as those involving oil, high temperatures, or fuel. However, if a specific clearance requires a certain gasket thickness, using a gasket might be necessary. It's important to choose the appropriate sealing method based on the requirements of the specific situation.
4. When should you not use RTV sealant?
If your assembly will have direct exposure to gasoline, it is not recommended to use RTV sealant. In such cases, a solvent-based gasket maker should be used instead. It's important to consider the specific requirements and potential exposure of the application to select the appropriate sealing method.
5. Can I use silicone instead of RTV?
Silicone can be used as an alternative to RTV sealant in some cases. However, it's important to note that RTV silicone can be more expensive compared to regular silicone. While many people use silicone due to its lower cost, it's essential to consider the specific requirements and compatibility of the application when choosing between silicone and RTV sealant.
