1990 Dodge Shadow iM not sure but I think something is wron

My problem started about 5 months ago whenever I would stop my car and release the brakes the drivers side near my back tire would make a loud pop well I tried to explain something might be wrong but no one would listen well today I tried to drive my car it would go fine if I wasnt pushing the gas but when I tried to accelerate it wouldnt go anywhere I couldnt go anywhere in reverse either and it makes a grinding noise when I try to go forward so theres my problem im not sure what it could be but I would be thankful if you could shed some light on this problem thank you
