yj axle into tj

So I just need a quick fix on my 2000 tj until I have the time to build up some dana 44's. What is the gear ratio in a stock rear dana 35 axle that came out of a 91 yj? Also would it bolt right into the tj?

no, it would not bolt right into a TJ. there would be lots of fab work to get the D35 from a yj into a TJ.
also, i believe there are 3 or 4 different ratios that were available in the YJ. 4.10, 3.73, 3.07, and maybe 3.55. which one it had depends on what engine, transmission, and what year the jeep is.

your best bet is to find a tj with matching gears and go for that.

why do you need a quick fix? gears? axle shaft? what went out? the gearing could be the same, look at the data plate. im pretty sure the spline is the same if its an axle shaft you need.

All the inside of my diff ripped to shreds pretty much and really was looking to upgrade to a dana 44 but cant seem to find any but that xj I just posted.

No. Same issue as the YJ. they have leaf springs. TJs have coil springs.

Also new brackets or no? It needs to be like legos where all the parts fit on everything. I guess it's keep on looking.

The only factory direct axle swap for a tj is from another tj! I have a mj Dana 44 in my tj and have no regrets with welding on a $200.00 bracket kit that was way heavier duty then the factory mounts. If you can't weld try taking it to a local fab shop and have them do it. It would still be cheaper then buying a d44 out of a tj. Look at your local you pull it type yard for axles, I payed $85.00 for my complete axle.

Yeah, already been to a few local yards around me and nothing. It all adds up quick.

And also would the "No pinion yoke" effect anything?

The only thing that is the same is it uses coil springs, the Grand Cherokee's bracketry setup and placement is totally different.

You would need to use the yoke off your d35 and torque it using a new pinion nut and a new seal while you are at it. The price he wanted was high for what it was. I would give him half that, but that would be it.

If I were going to have to do brackets anyway, I'd pick up an 8.8 out of an Explorer.

Been trying to find one. Would I have to get the stuff rda mentioned above for the 8.8 or just the brackets?

You would need a 1310 companion flange and have to modify your rear drive shaft if not need a sye and dc drive shaft. It also hangs much lower then a d44.

Dana 44 out of my 74 Chevy 3/4 ton, 8 lug?
73-79 dana 44 5 lug Ford?
Would either work well?

Neither would work without significant modifications. You would need a passenger side drop transfer case to use the Chevy axle and it's low pinion. Both axles are much wider then the 60.5" tj axle, 67.5" for the ford and 69.5" for the Chevy. If you want a new front axle buy a high pinion Dana 30 out of a Cherokee sport.
