Do I have to replace the entire rear end on my Ford Escape '01?
My o/d light started blinking while driving down the interstate. My Escape started jerking, vibrating underneath, and loud rumbling sound like it trying to change gears. It stop when I took my foot off gas pedal but return whe accelerating. It slowed to 20mph. I floored it still 20mph. It was hard to pull as if something was holding it then let go. When I pull over and shut the engine, it started again with no problems. Few feet the same problem. When my dad tried to tow it with his trailer, it made the loud rumble it was hard to pull like it was being dragged. The mechanic wants to replace the entire rear end. Is he correct?
