I have a 1998 F-150 with a 5.4L and a E40D trans and I had a broken tranny mount and I replaced it with a new one and i broke it within 5 days???? I didnt know if its because I have a 6 inch Suspension lift and a 3 inch body. I wanted to know if someone makes a polyurethane tranny mount or somthing??

 

If you have an angle problem that is causing the mount to fail do not put a solid one on there. You'll just bust the extension housing or something like that. You probably need to readjust your angle usually the rearend needs to be tipped up in the front a little and the transmission need to be lowered slightly. Have you checked the engine mounts? What about the U-joints? poor angles make for short lived U-joints.
