Bars Leaks Axle & Differential 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. Extends system life by stopping leaks, reducing noise and improving gear performance. Superior anti-wear, anti-foam and anti-corrosion protection. Works in all manual gearboxes, differentials, open & posi axles and more. Stops pinion, axle, output shaft and other seal leaks. Reduces grinding, whining, clunking and protects gears.
This Bar's Leaks product definitely helped with my differential issues, but I found it a bit messy to apply. The 16 oz. size was good, but I struggled to get it all into the differential without spilling some. Still, it did stop the leak, and that's what matters!

Disappointed with the Results
Unfortunately, the Bar's Leaks didn't work for my differential issue, and I ended up having to take my car to a shop anyway. I was hoping for better results since I bought the case of 4, but it just didn’t do the job. Might work for others, but not for me.

Effective Solution for Differential Issues
I used the Bar's Leaks Differential Gear Repair on my old truck and it worked wonders. The 16 oz. size is just right for my needs, and I noticed a big difference in the sounds coming from the rear end after using it. Definitely a solid buy if you're dealing with differential noise or leaks!

Decent but Didn't Solve It Completely
I tried the Bar's Leaks Differential Gear Repair after my mechanic suggested it. It worked to some extent, reducing the noise but not fixing it entirely. The 16 oz. case was enough for my needs. I think it’s worth a shot, but don’t expect miracles!

Great Product for DIY Repairs
I really like the Bar's Leaks Differential Gear Repair! The 16 oz. bottle is perfect for home mechanics like me. After adding it, I noticed a significant reduction in noise and smoother driving. I bought the case of 4, so I'm set for a while!
