Pumpkin Leaking.....What Could Cause this?

no problem. I actually did a full photo documentation of the process, but I never finished composing it.
it's odd to say, but it was actually fun though at the time I was going to kill myself because it was ungodly frustrating.
the last person to have removed my diff (when I installed the LSD) stripped the bolt holding the diff into the rear bushing... and it's deep so i couldn't fit any of the stripped bolt remover tools in there! we tried everything. that was a ....hurdle.
also, make sure to be careful of the speed sensors on the diff when removing it or when doing anything near the bushing (they hide up behind the subframe and are delicate)
and as long as you have a friend, you don't need a transmission jack to hold up the diff when you drop the mounts. it's only about 70 lbs or so.

like I said at the time.. my bushing was trashed so it's like going from shoes with no soles to air jordans...
but the changes I noticed the most:
- improved shift action (stiffer drivetrain) on the 6mt
- more predictable traction, and breakaway
- NO AXLE HOP <
there are others (like: the car can now literally fly, and shoots lasers) good effects, but these are the easiest to explain and least controversial. I think it improved the car a bunch personally... it feels different.
downsides:
- when cold, there is increased gear noise. once up to temp I really don't notice any difference (and I have a stock exhaust on now + test pipes/headers) in NVH.
it does not at all degrade the ride quality, but makes it better by isolating movement to the suspension, where it should take place. the subframe bushings isolate the road noise and vibrations very effectively.

apparently they are very fragile. you have larger, gripper tires, stiffer suspension...
did you ever launch your car at the drag strip? even when stock a little bit of axle hop can destroy it.
not just power causes it... and it could have been busted for a while. it's not really apparent or affects anything until it's really bad.

*the shops I have seen replacing subframe bushings usually use a blow torch to melt them, and I would do the same if I had dropped the subframe.
the new solid SPL bushing is not 'too' hard to put in, you use a TON of soap and a lil water to lubricate and you basically hammer the everliving hell out of it to get it in. SPL provides a tool so you don't destroy the beautiful anodizing on the bushing but it isn't the greatest tbqh.

A trick to putting in the new bushing is to freeze it overnight, that will cause the bushing to contract and be easier to slide in, though you have to work fast since the aluminum subframe conducts heat pretty well
That was a little joke, that picture of the subframe upside down is AFTER we had replaced the bushing (you can see the aluminum bushing on there). Gear oil leak will not stain the diff housing in that manner, like with any oil leaks it should be oily/gummy and can be cleaned off. The silicone leak from the bushing will stain the housing, and dry on like paint; we tried cleaning off the stain using brake cleaner and it won't come off.

The tool provided is to allow the use of a shop press to press out the old bushing. Orient it so the smaller diameter end sits against the rubber on the old bushing, then start pressing. It will start pushing out the rubber, and then the larger diameter part will hit the bushing sleeve. At that point it has "centered" itself on the bushing, and becomes straightforward to press out.
