Good day. Every one sorry this is my first post. Just got a second hand rav4 2door 1997 model. Just want to ask if anyone here encounter the same problem like mine. Everytime i take sudden movement like forward or reverse i here a sound at the back underneath. It is when i slightly step out of the clutch pedal immediately and going to jerk there will be the time always hearing that sound underneath. One mechanic says it might be the differential shaft or something... Do you have an idea? Thank you fo your help.
