My 87 turbo with 136k miles has a rumbling noise from what I thought was a bad rear wheel bearing. Apparently the previous owner thought the same thing because when I pulled the left rear spindle it looked as though the bearing had been replaced already. I went ahead and installed a new bearing and seals but when I test drove the car after wards the sound hadn't changed. I have tried listening with a stethoscope but I hear no distinct rumbling or difference in sound from either wheel.
Has anyone experienced similar issues? Could this be a diff carrier bearing? The rumbling sound is definitely emanating from the rear of the car. It is speed related but does not change pitch when I load the bearing by turning left or right. I have no drive shaft vibrations but could a u joint cause such a noise? The drive shaft seems tight with no play at either yoke. I had the car aligned after installing the bearing and all wheels/hubs spin true.
Any thoughts/ideas would be appreciated
