HELP!! Truck knocks HARD and shakes violently
1986 ford ranger 2.3L 2x4
So on the way home form work today driving on the highway My truck started knocking reallly loud and vibrating real hard. I drove it to a place where I could stop and checked it out....idleing it vibrates alot and idles rough, the motor is bouncin around like crazy, I thought I had broken a motor mount but the two I could see look fine. When I put it in gear and start driving it knocks loudly, and I hear a hissing as if air is being sucked in somewhere. I lost alot of power near teh end and I was basically running on like 20% power.
think my transmission is hooped?
Thank God it's the weekend and I can get it fixed or buy a new truck or something.
Any suggestions would be quite helpful.
