How to diag a bad limited slip rear end

[jay87lx]

I thought I recently saw a thread on how to diagnose a limited slip rear end but now I cant find it. It was something about lifting one side of the rear and see if the wheel spins??Or lifting the whole rear and see if one wheel spins opposite???
I have a 99 expedition that I suspect the clutch packs are gone and I am assuming the procedure would be the same?? If someone has the link to the thread that would be great- TY

Easiest thing to do is to just do a burnout. If you did a one wheel squeal, your clutch packs are shot. If you laid even 11s, rock 'n roll.

It's a '99 Expi. Better find mud. Like really really wet mud LOL

And chain it to a tree. [emoji4]

Yea, I was about to say, AWD too, that thing isn't spinning at all.

Most Expi's and F150's from 98-08 don't come with limited slip. Even my loaded '04 Lariat don't.

I think you can tell off the door sticker code for the rear end.

I definitely have a limited slip with clutch packs, that I am positive of.

There should be tag on the rear end that has the specs for the rear.

That won't tell him if he has bad clutches :burnout:
