try it in 3rd, 2nd and 1st, see if the noise changes

 

no it doesnt change the sound, but it only seems to do it after 1st gear

 

my blazer has the same problem but i dont have 4 wheel drive?

 

i think it might be bad or sticky calipers

 

maybe something to do with the ABS system?

 

i checked out brakes, i even changed the brakes and it didnt seem to be that but we brought the truck into the garage yesturday so when i find out whats wrong ill post it on here, thanks for the help though everyone

 

alright well the shop said the whinning noise was from a blown cv joint and the locking up was from a wrecked gear in the front diff. Thanks for the help trying to figure it out though
