My 97 4x4 getting a roaring in it!!

My 97 Tacoma 4x4 has 302,000 miles and nothing major ever done to it,still has the original clutch.I recently started getting a roaring that almost feels like it’s coming from my rear end. It’s a lot worse when I go up a steep hill in 1st and 2nd.It starting to vibrate the truck, It calms back down when you get more speed in it,I was wondering if anyone else has had this problem? Recently changed the gear oil in the rear end.It had some build up on the magnet but nothing major. No big pieces of metal. THANKS AND GOD BLESS

 

how are the rear tires ??

When some wear down they can do strange things.

Different Road surfaces can cause strange noises and vibrations
