What tools are needed for this job? is it a 14mm hex? do i need a pump to get the fluid back in there? is both the drain and fill 14mm?? I'm about to go buy the hex and wonder if I need any other size. I hate these strange sizes that no one carries.

I believe it is a 14mm hex key. Make sure you get a short one because it is a very tight fit in addition to the ratchet. You will also need a pump to get the fluid back in. I also believe both of the plugs are the same size 14mm).

Hello,
I had to change my differential fluid not too long ago and I had to look around for a 14mm hex tool also. I got mine on Ebay. The tool itself is made by a company named HAZET a German Company. It is imported by SAMSTAG SALES

It has a HAZET and a # 985 stamp in it

Hope this helps

BavAuto also sells the tool

anyone want to sell me this 14mm hex bit?

I believe a 14 mm hex head is all you need. I picked up a pump from the autozone for a couple of bucks. Stupid red-line fluid bottles are crap, so you can't squeeze them. I did my tranny fluid last weekend, but didn't have the hex wrench to do the rear. Make sure you get 2 quarts of fluid cause i believe the diff holds something like 1.1 quarts

I could not find a 14mm hex. craftsman don't make one either. I ended up ordering one from snap-on.

wish I found out about this sooner. My snap-on bit is $10 more.

If you don't have or want to buy the proper tool yet, you can buy a 14mm bolt with two nuts. Jam the nuts together on the bolt and use the bolt head to remove the plugs. It works well but its not elegant. Buy the tool later if time is important. Also buy a stalube pump. They are cheap and needed to get the new oil in the cases.

I bought a 14mm allen wrench from NAPA and a 14mm 6-point socket from Sears. I hacked off ~3/4" long chuck of the allen wrench with a cut-off wheel and glued in it to the socket :D

Thank you Bimmer95! You saved me re-posting this low cost solution. I don't even glue the hex-key stub into a socket. I just leave the 1" stub in my toolbox, and then slip it into a socket or box-end wrench as needed. The box-end wrench is helpful for limited clearance areas.

You can get a whole set of good quality hex keys and cut 2 or 3 stubs out of each for less than the cost of one Snap-On socket...

When cutting, remember to keep the hex key cool to retain hardness. I cut for about 5 seconds and then spray with water. I also keep the key clamped in a vise, which acts as heat sink.
