1991 Toyota Camry Repair Question
Toyota Camry Noise Problem
It is not your Fuel Pump.
Could be a myriad of problems; including low transmission fluid; bearing failure occurring in the differential; cv joints having a problem, etc.
You need to get it up on a lift and have fluid levels checked (if it is damaged because of worn out/ or low fluid - adding fluid won't fix it); suspension checked; drive shafts checked; etc.
If a friend has a lift - sign up for alldata; or purchase a good condition used FACTORY manual from books4cars.com or take it to a Toyota dealer. (diagnostics - figuring out what is WRONG is only about $136 total including taxes and shop towels in Seattle).
Serious noises like these need to be FIXED asap; or you might soon be losing a WHEEL; and dragging the rear end of your car down the freeway - modifying the body shape in not a good way; and hopefully not causing an accident in the process. Some things definitely should not be ignored.
