howl, squeak and clunker

[winsett]

Hi all...havent been in here for help in some time but I need all of your expert input on sounds and associated problems.

Heres my Rig:

94 Full Size Blazer
5.7L 350 (rebuilt with 200kms)..yes...it hurt itself with a leaky manifold..
Auto


1. Howling sound from rear end somewhere but only when I accellerate....some metal in my diff fluid but not alot (finger test)

2. "CLUNK" IN TRANNY WHEN AUTO-DOWNSHIFT

3. "GRINDING" sound in rear wheels when brakes applied and speeds <40km. - Also, when backing up a high pitched squeaking sound as the wheels rotate.


If you're asking yourself why I keep this truck on the road, the answer is that I'm attached to it. Pretty sure I got hosed with a reset odometer when buying and have paid into it dearly and deservingly.

I know from how many of the questions and responses on here and from past inquries, you guys are the best to get help from.

I would love to hear your response..
