## Questions & Answers

**Q: How many do you put in a rear for noisy bearings?**
A: You fill up the rear differential through the upper plug.  When the fluid starts running out of the hole, it is full.  Make sure you are parked on a level spot.  I doubt if it will help for noisy bearings unless you are really dry.

**Q: Can I use it for automatic gears?**
A: Bar’s Leaks Gear Repair is a treatment additive for use with automotive, heavy duty, agricultural, marine and industrial gear oils. Designed to mix with all synthetic and conventional petroleum GL-4, GL-5, MT-1 gear oil / lube grades including 75W-90, 80W-90, 75W-140, 85W-140 and all others.
