Bob Moore uses Lucas Power Steering Stop Leak for 86 celebrity wagon


I've been driving an 86 celebrity wagon. I was told the steering rack needed to be replaced and it would cost about $400 to replace it. I didn't really want to put the money in it in the beginning because it wasn't so bad, but now, it had no power assist when you turned right and very little when you turned left. So I've been muscling it around for about 3 years now. I put a bottle of your Power Steering Stop Leak in. I didn't really think it was going to do much. BOY was surprised, it cured it in just seconds. The steering is totally fixed, I'm amazed your stuff really works like it said on the bottle. I've been telling everybody about it. I can't thank you enough. I'm trying your other products as well. I am very glad to see that they are made in the USA.

Thank you,

Bob Moore
