What gears are in my Dana 44?

bhicks · Nov 10, 2009

I have a dana 44 from an 89 XJ limited wagoneer 4x4. It had the V6 and not the straight 6 4.0. It came with the automatic tranny. Is this enough info to be able to know the gear ratio or do I actually have to open the pumpkin up. Did this model possibly come with a limited slip in the rear? Also I may convert the donor vehile back to being road worthy so I can sale it. I may drop a dana 35 in the rear if I can't get my asking price with the Dana 44 in the rear. Will this drop right in or am I going to have a rear driveshaft that is too long or something?

Find the Dana Bill Of Material number on it. Seven digits, starts with a 6- like 6xxxxx-x. With an automatic it should be 3.55. 89's never had a V-6.

I thought the same thing, but I have seen the title and I have seen the eninge. I have no idea why, but somebody replaced the great 4.0 with the crapy v6. Thanks for the info on the gearing.

So I got the info on the gearing, now I need to know about a possible limited slip in the rear and the complications (if any) with swaping in a dana 35, so I can keep the d44 and sale it seperately.

You won't have a problem swapping it for a D35. I swapped a D44 into my old XJ (which came with a D35) and the driveshaft length was just fine for both axles.

As far as the limited slip goes, I would just pull the diff cover and look inside.

When you get the BOM enter it here:

Or you could do the usual check for a limited slip, turn one axle shaft and see if the other goes the same way or the opposite way with the pinion held.

If it goes the same way, what does that mean?

That's the clutches in the limited slip trying to turn the whole carrier as a unit. If the carrier doesn't try to move and the other axle goes the opposite direction, it's an open diff or a really worn out limited slip.
