Hi,
Wrangler TJ 2.5 1997
VIN 1J4FYN9P3VP491639
can anyone confirm that my rear diff is indeed a Dana 44. Looking at the charts I've found it certainly looks like the 44. It has the metal filler plug.
The numbers stamped on the diff cover read
42960 1
439 5
REV S
08 03 95
Pics attached.
Many thanks

Looks like one to me clean up the data tag with a wire brush, it will tell you the ratio :icon_winkle:

Looks like a D44 to me too
What do you need to know for?

Quote from Doctor Mike back in 2006
All UK supplied TJ's were equipped with Dana 44 trac loc rear diffs
UK supplied RHD jeeps have the D30 up front. The YJ, XJ and ZG had D35 rears (except most of the 4cyl petrol XJs which had Chrysler 8.25 for some reason), The WG and TJ have D44 at the rear.
All YJ,ZG,TJ and XJ with 231 t/case had LSDs, XJ after 1996(I think) with 242 T/case did not. WG had the Variloc differentials front and rear if ordered with Quadradrive, otherwise they were both open.

It's a D44 , with a nice new exhaust.....

Thanks for the replies. I've got a noisy bearing (finding it difficult to determine which one) and have been pricing up the bits and just gestimating how long to do the job if I have to do the axle bearings or the diff / pinion bearings. Also the tools I would need.
Noted that there is a big difference in prices between D35 and D44 bits.
Thanks again

Normally it's the pinion bearings (or for me it has) but replace ALL the seals at the same time ...

If your local to Brum or can drop it off, talk to Kev aka Bubba on here, he's done plenty & has all the tools, especially the bearing pullers, vital to help setting up without damaging stuff.
Check out Randys ring & pinion for parts :icon_winkle:
Been there, done this & would highly recommend this route

Bear in mind, what it says on the case may not be what's inside.
Line's the standard case, but inside is a very different locker with a very different ratio.
With cars this old, with so many custom parts available, you can't be sure what previous owners have done.
-
Thanks again all.
Think I'll go for doing the outer pinion bearing and seal. There is a ting leak in that area. Been meaning to buy a bearing puller for ages anyway.
Watched a few U tube vids and they reckon marking the yoke, pinion and pinion nut well to ensure it goes back in the right place and as a rule of thumb around 180lb ft on the torque wrench then check with an in lb torque.
Anybody think any different?

If it's a low frequency wheel bearing scraping type noise, it's carrier bearings, if it's a high frequency wail that doesn't change on/off power it's pinion bearings, if it's a whine that changes on/off power it's gear noise due to wear or incorrect setup. If it's anything other than carrier bearings, you're wasting your time not doing a complete overhaul.

Yup that my reckoning too
