Here is some very good info on the the 44hd 44a 44If the housing is oval, it is a D35. If it is not a perfect oval, it is a D44HD (Aluminum). The 44HD is very different than the other D44 diffs.
The easiest way to test is to grab a magnet off of your fridge, and see if it sticks to the bottom of the rear diff. It is a 30 second test, go do it.
You should be able to pull the CV's and axle shafts out both sides and fit XJ or TJ Uni Joint type axles straight in..... but it's a VERY close fit!(some times you need to enlarge the holes.).....if buying NEW, make sure you get axle shafts that have the Tone Ring reluctors pressed on so that your ABS keeps working!.....,also get ones for 95 and later which had the bigger Uni Joints. TJ's didn't have ABS and I think only some XJ's had ABS.What Is the WMS (wheel mounting surface) for the Dana 30 on a 95 ZJ? Ive been looking everywhere and need to know the exact measurement not the guesses. planning on upgrading to u-joints and figured that i might be able to get some shafts from a TJ, YJ, or XJ. Sick and tired of dealing with torn CV boots.
damn. and to think i thought this site was family friendly.haha k thanks I'll go yank on it then
I believe only Quadra-Drive does, That's the only difference I know of between Quadra-Drive and Quadra-Trac II. The NV-247 is a Quadra-Trac II T-case and the Vari-Lok is the pump system in the differentials that splits the power between the left and right wheels naming the system Quadra-Drive. Where Quadra-Trac II can only transfer engine power to the front or back as needed, Quadra-Drive having Vari-Lok allows power transfer to the front and back and left or right wheels individually as needed. Jeep claims "Even if only one wheel is on the ground, Quadra-Drive will send all the power to that one wheel and keep you moving."Does the NV247 Quadra-trac II also have veri-lok or is it only the Quadra drive? I know the Quadra-trac has some type of limited slip.
Just a side note, the 45RFE can be a 545RFE. The only difference is a PCM flash from the dealer. my 2000 had it done way back in the day.Now for Jeep Transmissions
