Review on 🚗 Enhance Your Ford's Performance with Torco AFM0050JE Type F Limited-Slip Additive - 4oz by Delbert Potter

Saved me over $1000 on a new rear diff! I bought a 2004 GTO with a six speed manual transmission and an LSD rear diff. After installing new tires, I noticed a rattle in the rear differential after a long drive. I changed the fluid to Torco 85/145 racing grease and added this friction modifier. He took care of the noise! 95% better. I would still hear intermittent noises here and there but NOTHING like it was. yes, just in case I drove it for a month then changed the fluid again with Racing Gear Lube and this modifier again and the noise was 100% gone!
