How do I know if a throw out bearing is going out

hi barb. yes it could be a throw out brng.the simplest way to tell is to listen carefully {we use a stethoscope for this} but with the truck idling in neutral put your foot on the clutch and just barely move your foot to engage and disengage clutch listen does the noise change when you do this?? if yes throwout bearing is bad if no a trans bring or even worn gears in trans. but honestly most of these trucks will make this noise when they get a few miles on them. so prob not an emergency just a prob down the road. but make sure the trans is full of fluid. this video and guide can help

Please run down this guide and report back.

Hi Barb, Billymac is on the right track, and I would also replace the trans fluid with 15w-40 engine oil or synthetic 50W Transmission gear oil. We use the 50W in all of our manual transmissions here at International Truck and have had very good results with it. It keeps the gears lubricated well and they run quietly. Ford uses ATF in there transmissions and I believe this is too thin a oil for the heat they work under. Try this as it has helped quiet trans noises. I did this on my Ranger and it made it run smooth and quiet. Craigfer
