Smooth driveability and reliability depend on having a driveshaft and universal joints in good working order. A Mustang's driveline is something you want to know is there without being able to feel it.
When the driveshaft and universal joints, or U-joints, are felt and heard, it's usually bad news. These quality, replacement style universal joints connect your fox body Mustang's driveshaft to the rear end pinion yoke and will get your driveshaft turning smoothly again. Sold as each.
Working in a customer service oriented job I can truly appreciate minute by minute notifications and incredible customer service. I am building my seventh fox and have dealt with every known distributor on the planet and LMR is by far the most efficient and thorough company I have dealt with.(twisted wedge top end kit and supporting equipment project starting this week)
