Things to check after belly-draggin

[SubaCool]

After our last offroad run (Yankee Hill) we've noticed a slight whine coming from the rear of the car at higher speeds (only under throttle). I've looked and looked and couldn't really see anything wrong but finally got it narrowed down to the rear diff area. I've checked the fluid and it was showing signs of wear and possibly mud (I know, need a longer breather tube), so I've decided to start with replacing the fluid. Yesterday I got underneath to change it and while I was arguing with the skidplate taking it off I've noticed the side mounts on the diff crossbar. One of them took a hit on a rock and it bent the whole mount back about 1/4 inch. It looked almost intact if it wasn't for a pinch on the bushing. It misaligned the diff a small amount, but I guess that was enough to create metal to metal contact and it was resonating throughout the frame (thus creating the whine).

I was able to use a pry bar and a hammer to move the mount back forward a bit but didn't want to move it too much as I didn't want to stress the welds anymore. It's still a little rooster eyed but it doesn't whine anymore (resonate). Now I'm not sure if the welds got compromised but it appears to be fine. I'll get it checked out soon though.

I've just thought somebody could use this info, learn from my mistake If you ever end up dragging your belly and then hear weird noises from the back, check the rear differential area. Oh, and always pay close attention to things, it took me 4-5 inspections to finally notice it on accident
