Rear end shudder - not while turning
Hey all, this is starting to bug me, so I'd like to get some input on it.
Bought an 04 New Body Supercab w/ 97,700-ish miles on it, about two months ago. Since about 98,000 miles, it's had a "sometimes" shudder when taking off straight from a light or dead stop under light throttle.
It doesn't do it while turning, it doesn't do it if I give her hell when taking off, and it doesn't even always do it.
If I'm paying attention, I can actually count the "skips/shudders" it makes - between 5 and 7 most times, and it does it for between 1-2 seconds on take off.
I'm fairly certain it's not misfire; I've got no CEL, the 4.6's idle is smooth as glass, and there's no vibration when I give it very light throttle in park or neutral.
It doesn't impact the driveability of the truck, but it does irritate me when it happens. Any ideas? I'm already planning to change the rear differential fluid and additive when she turns 100k, along with plugs, oil, filters and trans fluid check, as I don't know much about the service records.
Thanks for any input.

does that mean it probly has limited slip and needs friction modifier too?
