I have a 95 F150 2wd 5.0 automatic. Lately there has been a strange wooshing/squeeking sound coming from the rear of the truck somewhere when I back up. Sometimes when I turn or go over a good sized bump something pops. Don't know if the two are related. Any help would be greatly appreciated.

Thanks

 

check your spare tire, to see if it's fully secured,I had the
same problem, until I saw the spare tire shaking going over a
speed bump, (friend was driving my truck) so I tightened it up
and noise gone, what I did was,take my floor jack and jacked it
up until it justed touched the tire rack, then gave it a couple
more strokes until I saw that the tire and rack had no more slop
in it.... hope this helps you,....
