This problem has been lingering for almost 9 months now and nobody seems to know the answer, or they just tell me "its a 20 year old car, what do you expect?"
I'm aware its 20 years old. I'm just trying to make it right again.
Its a 1985 Corolla, RWD, SR5. I just had the driveshaft rebuilt. Here ar e the symptoms I'm getting:
- Rumbling noise and vibration from about 30 MPH to 65 MPH - independant of gear or engine speed. Just as bad in neutral as in any gear
- Had a stethescope hooked up to it, very little vibration coming from the support bearing itself, and a significant amount coming from the rear end and transmission.
- The rumbling and vibration ONLY STARTED when the driveshaft was replaced.
My question is this - could the tranny or driveshaft been ruined by the installation? Could the driveshaft still be out of balance, even though the reading is low on the support bearing? My mechanic said he was sure that the shafts were in phase with each other. How can I check this?
Maybe I just have a shitty driveshaft?
Any responses are appreciated. I'm sick of getting a headache whereever I drive.
