2006 Tacoma making a rattling sound

Just got an alignment and changed the diff fluid. Picked it up from the shop and noticed a rattle. Loose heat shield or exhaust?

take a look at the dust shields on your front brakes. Might need to bend them back away from the wheel a little bit.

edit:
You most likely will need to remove the two front tires to bend it back.

 

Thanks dude much appreciated!

 

Check the skid plate.
It needs to be removed to drain the front diff.

Step 1 for me would be smacking the bottom of the skid plat and listening for sounds.

 

I'd say skid plate or dust shield. When I get oil changes sometimes they forget to tighten a bolt and it sounds similar to that. But yeah smacking the skid would tell you if its that
