My 2000 Toyota Camry is making a deep groaning sound when accelerating?

My 2000 Toyota Camry is making a deep groaning sound when accelerating, especially in middle RPM's. It seems to get louder if I drive it longer. It never used to be this loud up until recently. Any ideas if this could be serious or what it could be?My 2000 Toyota Camry is making a deep groaning sound when accelerating?does it seem to be related to engine speed? or the speed of the car?

if engine speed related it could be a waterpump bearing or a timing belt idler. if vehicle speed related, it would be a frt axle bearing---try turning and shifting the weight to the left and rt while driving; get louder? or quieter? any play in the wheels? the 4 cylinder has a separate differential fluid chamber--is there fluid in the differential?--it hard to check without a hoist as the fill plug is on the back cover and most oil change places forget to check the level. It could be serious, so dont delay getting it checked..the side of the highway is not where you want to have to work on your car. good luck.

Could be that you're running low on transmission fluid. Or that your fan belt needs to be repaired, but that'd be more associated with a high pitched sound.

Anyway, yeah, I think you're out of transmission fluid.My 2000 Toyota Camry is making a deep groaning sound when accelerating?Have an experienced driver or mechanic test drive it,can be a lot of things.Do not fix car by speculation,it is costly and more problem like open up a can of worms.The sound has to be heard and felt.My 2000 Toyota Camry is making a deep groaning sound when accelerating?
Could be serious. Take it to a trusted mechanic.My 2000 Toyota Camry is making a deep groaning sound when accelerating?out of tranmisson fluid or you have alot of miles or fan belts
