Completed the front differential fluid change yesterday using the long hex bit socket. It was still a pita with the metal lines on the way. First I tried to bend them slightly out if the way but abandoned that in fear of damaging them as there is not much leverage to bend them from underneath in that area. I kept trying from the wheel well side and almost gave up but one final chance after connecting another medium long socket extension I was able to force the long hex bit in. I could see the metal line moving slightly aside as I was pressing in to fit the hex bit. An extra long hex bit socket would work and reach much easier.

Proceeded with the drain from underneath then the after putting on a new drain plug and torquing to spec I filled up the differential with Redline fluid using a fluid transfer pump that fits standard quart bottles. After the fluid starts to flow out of the fill hole I knew I had enough in there. Then now back to putting on a new fill plug. Starting the thread was not going to happen easily as there is no space for fingers down there and the hex bit cannot carry the fill plug to start the threads past those metal lines. I ended up attaching the fill plug to a magnetic telescoping pick up tool and reaching in through the wheel well to start the thread and screw on as far as I could. Then used the long hex bit to tighten and torque it to 44ft/lbs. Took me a little while to insert the hex bit to the bolt just like the first time. Next time I would use an extra long hex bit socket as it would clear through both the rubber boot and the metal lines as shown in the pic on post #12. Patience is required for this DIY. Sorry I didn't take any pics.
