Hey k so i have a 1990 f150 4x4 5.8L w/ E4OD trans, my door jab sticker says H9 for my axle code, so that means i have a 3.55 limited slip right? and if so then both of my tires should spin right?

if u jack the rear end of your truck up and spin the one tire, the other one should spin the opposite way

look directly on your axle theres a tin tab that will have a 3L55 on it of its limited slip if not it will just be 355

yeah my tab does say 3L55 but like when i life up the rear end they do spin the opposite way but my friend also has limited slip and they both spin the same way

You may haave a very, very worn out limited slip.
Or a previous owner may have replaced the LS with an open

oh arlight so how do i see if it's worn out when i pull the cover?

After 18 years it is a safe bet the clutch pack is toast. Fastest way to tell is to stand on it. One wheel peel or both hookin' up and spinning you around will determine it right quick.

yeah so it's toast, thank's for all the info and help, one last thing to fix it i have to install new friction and clutch plates right?
