wolfman_dlc Posted November 13, 2011 Share Posted November 13, 2011 OK. Last night I hit an (already dead) large dog on the freeway in my 280zx. I didnt have an option not to hit it so I aime for dead center. Unfortunately my car was too low and I high centered feeling like I hit a speed bump at 60mph. Immediately after I hear a loud whine from transmission area. I put it in nuetral, pulled over, shut off engine. I didnt see any fluid or obvious problems and had no cell phone on me so I started her up. When I started her the sound was gone, gave her a few revvs just to check and had no problems. Forgot to mention This is a three speed Automatic with 240,000 miles. I decided to drive her home and as soon as the wheels start to spin the noise begins and grows very much worse when letting off the gas. It is mostly consistant with road speed as I put it in neutral at 40mph and had no change when revving up the engine. It sometimes sounds like a rod hitting the oil pan, sometimes like a warped rotor rubbing a brake pad. From where the sound is coming from my best guess is either torque converter or transmission. Can anyone shed some lite for me. This is my daily driver of 100miles per day. Daniel Quote Link to comment Share on other sites More sharing options...
Miles Posted November 13, 2011 Share Posted November 13, 2011 Could be any number of things. Need to get it up on a rack and inspect everything. May be something simple. Quote Link to comment Share on other sites More sharing options...
wolfman_dlc Posted November 13, 2011 Author Share Posted November 13, 2011 Jacked it up today and could find no damage. No dents in the oil or tranny pan. I even removed the fly wheel inspection cover and found nothing wrong. Suspension and wheels all looked and felt fine. Car drives absolutely normal other than it sounding like its gonna blow.

Miles Posted November 13, 2011 Share Posted November 13, 2011 When you inspected under the car did you try turning the drive shaft, half shafts and wheels by hand while listening for noise/slop? Quote Link to comment Share on other sites More sharing options...
wolfman_dlc Posted November 13, 2011 Author Share Posted November 13, 2011 The front wheels I did. The rear half I havent yet, but I will in the morning. Thanks for the replies! Daniel Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted November 13, 2011 Share Posted November 13, 2011 The heat shielding is rubbing your driveshaft. Check the shield that bolts to the frame rails.......it goes over the exhaust but below the driveshaft. Quote Link to comment Share on other sites More sharing options...
