    I have a 2002 4x4 and I need (way past due 110K:() to start looking at changing the fluid in my transfer case and rear differential. I see that the transfer case looks easy.



    My question:

    I can't tell if I have a Traction-Lok (limited slip?) or regular differential. Any help would be great.



    Thanks,

    Michael

    Look at the tag on the tranny or on the door jam.

    Thanks Tom.



    Looking at you fog light fix, how do I know if I have a Job 1 or 2? I am doing that today!

    By the build date located on the door jam.



    That little tag tells you a buch about the vehicle you own.

    Here is the codes for the differential type (copied from another post):

    46 � 3.73 non-limited slip

    42 � 4.10 non-limited slip

    D4 � 3.73 limited slip

    D2 � 4.10 limited slip

    Thanks guys for all the info. I see I have a D2 so its a 4.10 LS Diff. Again, thanks for your help!



    Tom, I show a 01/02 date and I also see the relay box next to the air box, so I hope to make the fog light fix today.

    Well I opened the diff cover and a few gears a chewed up and I have metal flakes/bits all over.



    I thought I had some chattering, but looks to be more than just that.



    I know I need to replace the gears.



    Do I replace the axels and bearings as well?



    Can I fill it back up with oil a wait to get all the parts in (few weeks) or do I park it till its fixed?

    I was all ready to change oil in my 07 trac rear diff. I have the 3.55 with the 3/4 in. drain plug . I think I am ok removing the fill plug if I can find my 3/8ths ratchet but I have a problem . My 1/2 in.drive with the 3/4 adapter wont fit in the space because the end of my half in. ratchet is too thick . I might be able to place the adapter in the sq.hole and use a pipe wrench on the adapter I just dont know and I am open to some suggestions . I'm sure a swivel wont work here because of the angle .
