limited slip shudder
My 08 with the 3.73 limited slip I believe is making a shudder on takeoff. It just started maybe a month ago from a dead stop turning. Well its starting to do it going straight. It feels like a clutch pack shudder to me but the straight takeoff makes me wonder. It has about 130k on the truck and I don't know if the fluid has ever been changed in the rear. I'm planning to do it but wonder if that's what is causing it.
Thoughts??

Almost always a fluid change gets rid of this problem. It has for me twice, once on my 1965 Chevelle that had a 12 bolt eaton posi-traction back in 1968. More recently it got rid of the problem on my 2000F150 5.4scab 4x4 that had the 9.75" ford traction lok. On my 2000 I had to put two bottles of friction modifier in it because that year the clutch pack was shimmed a little too tight.

I agree with what these guys have said however, every case is different. Change out your fluid and be sure to add a bottle of XL-3 friction modifier. Hopefully this cures your condition but if it doesn't then it is time for a LS repair.
If you're like me and don't ever want to worry about this issue coming up again, then replace the factory LS with a Detroit Truetrac. The truetrac is all helical gears that won't wear out like the factory LS clutch packs will. I never had the shuddering issue with my LS but I changed it out to the truetrac anyway because I never wanted to encounter the problem. The truetrac works better than the factory LS anyhow.

I changed the diff fluid on my truck long before I took it in for the gears and truetrac and I used nonsynthetic gear oil with 2 bottles of XL-3 and the truck behaved the same as it always did.
