... at some point :o After our last 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 brackets on the diff crossbar. One of them took a hit and it bent the whole bracket 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 it 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 **** eyed but it doesn't whine anymore (resonate). Now I'm not sure if the welds got compromised but would somebody be willing to take a look at it and tell me? I can't afford to take it to a shop and get it checked out (or re-welded) at the moment (no jobs), I just don't wanna lose my diff somewhere. I hope I'm not asking too much :o
