i have a 06 f150 XLT that vibrates and shakes in the rear end when i turn right or left for a complete stop it went away when i fixed the booster pump but its back again any ideas?

 

it shakes while braking and turning at the same time or it shakes everytime while turning?

 

only when turning

 

clutches in the LSD,(the diff)

 

does it have the right fluid in it? and does it have friction modifier in it? has the truck sat for a while? i know of a couple vehicles that will do that after they sit for a while. they eventually straighten themselves out after a good drive.

 

i have the same problem on my 2005 f-150,but i've juste making a oil change in my rear diff, and the garage where i put it the said that they respect the ford condition, and the noise start just after my oil replacement,my truck only have 120 000km..is that normal?

 

It's a normal thing. It's the LS trying to lock up because the two rear wheels are moving at different speeds.
