Lucas oil stop leak?

I have a small leak on my front diff seal, passenger side. Would it be OK to use the Lucas engine oil stop leak in the front diff? Lucas says it will work and has worked. Detroit Tru Trac diff in the front. How much could it hurt to try? I will have to pull it all down for the leak and replace all but pinion seal. If it works it would be a great way to cheat my way out of a lot of work.

Lucas stop leak

I can tell you from experience lucas does have great products but the stop leak is not one of them.I have a dodge neon as a DD,with 2.0 4cyl. and it had a leaking rear main for about 25k and I had run the oil stabilizer in it and that keep it going.I decided to try the stop leak and that was a big mistake!I put it in and drove to work 80 mile round trip, oil was pouring out of it! Lost 2 quarts in 40 miles and another 2 on the way home.So I done an oil change and went back to the 30 wt. oil and Lucas stabilizer.Back to about a quart every 1000k.Had seal replaced and all is good now.Moral of this is, just replace the seal as soon as you can.Their stop leak didn't work for me and its the only thing they make that I don't like.

You may want to try Lucas Oil Stabilizer. It will probably slow down or even stop your small leak. Lucas says it can be used in 50 to 100% mix in a diff.

The advice I got is from the Lucas oil tech department guy. The oil stop leak is thick like the stabilizer and there is no oil preasure on that seal. I would never take advice from just any guy said so, like here;-). I will probably give it a try and report back.
