I've lots of experience with various chevy LSDs and and import ViscusLSDs and what not.. this is my first ford 8.8 TracLoc.
The clutch packs chatter pretty loud on corners... after the diff fluid is warmed up. Not when it's cold.
Sometimes it's just a loud whine, some times it sounds like metal biting metal as I feel the packs jump, rather than slip.
It's a rebuilt diff with new steels and fibers. Full of Mobile 1 full synth 75w-140 and a bottle of Ford Friction Modifier.
When the diff is cold, or just staring out. it's quiet. After a bunch of miles when I assume the oil is warming up, she gets louder and louder.
I spent about 10 minutes last week doing slow figure 8s in a parking lot. Didn't change anything.
Is this typical of the 8.8 TracLoc? Should I just keep driving for ??? miles to see if it goes away?
Do I bite the bullet and re-do the clutch packs? Is the fact that it doesn't start until the oil warms up something to look at?
Advice?
