John Chenault uses Lucas Power Steering Stop Leak in 1994 Geo Tracker

The output shaft of my power steering gearbox was leaking profusely. I usually used about a bottle of power steering fluid every couple of days. I checked into replacing the seal and was told by my mechanic that you cannot get only the seal you have to replace the gearbox and it was $1200.00 from the dealer. I decided to try your power steering stop leak and immediately noticed a great improvement, I continued to add only your product and am happy to report that after the second bottle I haven't had to add any fluid for three months. If it hadn't happened to me I would not believe it. Now I use all your products and have had positive results with all. Thank You for making products that live up to their claims.
