My Formula had developed somewhat of a mystery noise in the rear end. I'll start off to the events leading up to the noise. I had replaced the rear brake pads about 1 month ago, about a week later the tq arm bushing broken compiled with a broken tranny mount didn't make for a driving experience. When I got the car fixed it was fine for about 1 week. Now I'm starting to develop a noise from the rear end area.

It seems to be more concentrated on the passenger side. I went out tonite to look at things. There's oil on the passenger side of the pumpkin, the driver side is clean as expected. I do have a nasty rear main seal leak, I doubt it's engine oil because the tq arm is clean where it meets the rear end.

The noise sounds almost like a sticky pad. It eventually fades away in less than a minute.Then I don't hear it again till the car is parked for a half hour or more. The noise doesn't get stronger or go away when I round a curve. There's hardly any noise while in reverse. I have 107,5xx miles. The rear end fluid has not been changed since I owned the car, the previous owner did not have it changed either, I asked him.

Could the broken tq bushing/trans mount cause enough movement to put any seals out of spec?? I need some help guys, thanks.

 

where at on the pumpkin is it leaking at? the differential cover, or by the driveshafT?

 

It looks like it's coming from the axle tube and up near the driveshaft.
