ok i have a 03 f150 4x4 70,000. it seems while turning from a dead stop the rear tires are trying to catch up with one another . it vibrates the entire truck its not a clicking sounds but just the vibration and screetching minimal of a tire. .. is this the differential going bad??? or what some firestone mech said something about the limit slip dif centerline and something else being bad ? whats really going on???

it almost sounds like the spider gears are welded together to me

well i dont think they are i jacked the rear up on one side and was able to spin the tire just on the one side with the other on the ground. the left tire def seemed a little harder to spin. so i guess that rules out the spiders. it seems like the rear is kinda hopping around while turning. i just got the truck friday called the dealer today he said he will take care of it. yeah worst case it will cost 800 bucks. i am sure they are going to wanna just for over the repair bill

i would say inspect the rear brakes it sounds like you may have a caliper sticking or something specially if its only happening from a dead spot could be totaly wrong but anythings possable. good luck!!

does not do it while go straight from a dead stop though kinda sounds like rrr rrrrr rrrr rrrr till the truck straightens out just a min turn does it as well.

What does the term spring pack mean. Thats what the mechanic said might be the issue

06fordf150

the leaf springs i was thinking that also! could hav a cracked leafspring or shackle!

jvislax32

not sure a leaf spring is what i ment inside the limited differential i believe mine has one where as there is a clutch plate inside and stuff

06fordf150

well you may have a broken spring in the clutch pack which is not alowing it to disengage!
