Review on 🔧 High-Quality Ford Fluid XG-8-A PTFE Lubricant - 1 lb.: Genuine Performance for Optimal Maintenance by David Burns

My truck "knocked" when stopped or at traffic lights. This was the result of driveshaft seizure when the suspension was stretched or compressed. I have tried other lubes but the results have always been temporary and the problem returned after a few hundred miles of driving. I have driven over 1600 miles since installing this lube and the symptoms have not returned. I'm curious how long it will last, but this is by far the best lube I've found.
