Because a video is worth a thousand pics:
I spent the better part of the day swapping my diffs – pumpkin for pumpkin. That is a BIG one man job! The JZX pumpkin makes the Nissan R200 housing seem like a tennis ball. Having now swapped both types solo…this was a BEAST! To jump to the punchline, it was a success. I emerged from under the car beating my chest yelling “I AM ALL THAT IS MAN!!!!!” Seriously, I was ecstatic to get the first front mount bolt started; at that point, I knew I had it. I got it in on the first try. All be it that try was a 30 minute wrestling match, but I never had to put the diff down to restart. PROUD.
I didn’t snap any pics of the removal or install since it is a well documented and incredibly straight forward process. Instead, after getting the old diff out, I spent a few minutes coming up with a possible fix for the rear diff’s nasty habit of puking gear oil out when it gets hot. My goal was threefold: help the breather breathe easier; keep the fluid in the diff; and keep outside contaminates out. Here’s what I came up with:
A side note, I noticed this two casting differences on the two diff covers. I don’t know if they mean anything, but I thought someone out there may know. My guess is it’s an indication of open or torsen differential since those are the two options. Or, it’s just a production run marker.
I am sore, tired, and going to bed!
