Q5: How to take off a frozen filler plug on my truck differential? 

A5: To remove a frozen filler plug, apply penetrating oil to the plug and allow it to soak for several hours. Use a breaker bar or an impact wrench to gently loosen the plug. If it still won't budge, apply heat with a torch around the plug to expand the metal, then try again.

Q6: How difficult is it to replace the rear differential on a car? 

A6: Replacing the rear differential can be challenging and typically requires advanced mechanical skills and special tools. It's recommended to consult a professional mechanic unless you have experience with such repairs.

Q7: Is it safe to jack a car up under the differential? 

A7: Yes, it is generally safe to jack a car up under the differential, provided you use a proper jack and jack stands rated for the vehicle's weight. Always refer to the vehicle's owner manual for jacking points.

Q8: What happens if your rear differential goes out while driving? 

A8: If your rear differential fails while driving, you may experience loss of power to the wheels, unusual noises, or difficulty controlling the vehicle. It's crucial to pull over safely and have the vehicle towed to a repair shop immediately.

Q9: How to identify a Dana 70 rear axle? 

A9: To identify a Dana 70 rear axle, look for the identification tag on the differential cover, which will have the model number and gear ratio. You can also measure the ring gear diameter, which is typically around 10.5 inches for a Dana 70.

Q10: What causes differential overheating and how to prevent it? 

A10: Differential overheating can be caused by low fluid levels, poor-quality fluid, or excessive load. Prevent overheating by regularly checking and maintaining fluid levels, using high-quality differential fluid, and ensuring your differential cover has adequate cooling features, like the SPELAB Cooling Differential Covers.
