Review: Bars leak for rear ends - This is amazing stuff. I’m impressed. Had a leak on my 2013 Jeep Rubicon rear Dana 44 sealed it up almost immediately it was just barely weeping, but it is totally dry now. Left rear seal pretty good stuff. Review: Worked perfect!! - I had a small leak on a Kawasaki 4x4 ATV. Added about 6oz to the rear diff, and it solved my issue the same day after about a 30 min ride and spray down with brakleen. Zero drips for the last week or so Seems to have worked perfect and performs as advertised. Actually pretty impressed. Was planning on doing a full labor intensive rebuild, but took a chance on this. We will see how long it lasts, but so far so good! ## Features - STOPS PINION, AXLE, OUTPUT SHAFT AND OTHER SEAL LEAKS: This is a treatment additive for use with automotive, heavy duty, agricultural, marine and industrial gear oils. - ANTI-WEAR AW AGENTS: Superior anti-wear, anti-foam and anti-corrosion protection. - SEAL CONDITIONER: Extends system life by stopping leaks, reducing noise and improving gear performance. - PERFORMANCE ADDITIVE BOOSTER: 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. - Manufactured in the USA, this product works in all manual gearboxes, differentials, open & posi axles and more.

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.
