Hi Scotty, first let me say that I really like your videos. I just had an expensive issue with one of the products you suggested though. I had a VERY minor leak in the rear axle pinon seal. I had very recently changed out the fluid with Mobil 1 synthetic 75-90w fluid when I watched your video regarding the AT 205 sealer product. I thought it couldn't hurt and put some of this sealer in it. BIG MISTAKE!!! A couple of days later I noticed that the rear end seal was leaking like a sieve all over my garage floor. Took it to a mechanic and later he called me back to the garage to check out what he found. The seal was all bunched up and the mechanic said that it looked like some kind of sealer had been added that was not compatible to that type of seal material. I played dumb and did not admit putting in any sealer. He said that most likely the axle seals were probably also compromised. He is now pulling the axles, replacing the bearings and seals for about $1,500.00 parts and labor. This is on a 2003 Chevy Tahoe with 127K miles. I also have a very minor rear end seal leak and had also put this product in when the oil was last changed. No problems so far, but I will be draining/replacing the oil, just in case. Word to the wise and all...

Thanks,

Noel King

I've used AT-205 in 3 of my vehicles with no issues whatsoever.

I find that hard to believe, because the only thing it does is rejuvenate rubber seals. And that should have rubber seals . BUT , if someone put some other weird kind of sealer in before, the reaction with the AT 205 could have created a problem. It will not with regular rear end oil or tranny fluid or engine oil.

If that happened to me, during the same minute I'd be on the phone w/ AT-205 Re-Seal manufacturer. And I'd let them tell me what their research supports as far as what happened to those unsuspecting seals-- That said, you don't specify your make-model-year-mileage. It's possible your seals were compromised already-- dried out, torn, brittle, e.g., and *** possibly needed to be replaced anyway***. In other words, if the seals were beyond the capability of a sealant product, blame cannot be placed on AT-205 Re-Seal.
