Bardahl 3119 Gear Oil Additive + StopLeak - Extreme Pressure Lubricant Extends Gear Life and Stops Leaks by Conditioning Seals - 8 oz. (Pack of 1)

I bought a used 2007 Chrysler Pacifica that ended up having a read differential leak which turns out not to be serviceable. (You need another diff). As a last resort I bought the differential conditioner / sealer and to my surprise the leak stopped . Have since put 1500 miles on the car and still clean and dry. As a last resort I would definitely recommend.

Good product, everything is fine

As described sure hoping it stops or slows down yoke and axle seal seepage.

Had a small leak in differential seal on my ezgo golf cart. There was always a spot about the size of half dollar under cart after a round of golf. Since they wanted $400 to replace seal because motor had to be removed gave this product a try. Worked great, after two rounds of golf leak is completely gone!

No noticeable difference,

Seems to have solved the oil leak problem.

At the age of 58 years old, Ms. American 3.14159 (the ONLY 1964 Ford Galaxie 500, Four-Door, Hard-Top Police Interceptor that is found on the WHOLE World Wide Web) had a Transmission Seal begin to leak. Got a Tube of Bardahl Stop Leak, and wonder of wonders, it fixed the old Gal's Transmission. Thanks Bardahl. She needed THAT! JCAllison

I SEE NO SLOW DOWN OF LEAK. will update @ 2 weeks, been another week still I see no slowing down of leak. Will update again..ok been 3 weeks since added to transfer case and still have leakage. Lower my rating to 2 stars, JUST HIGH PRICE LUBE....NOW BEEN 3 MONTHS STILL WEEPING, AGAIN JUST REALLY HIGH PRICED 80-90 GEAROIL....
