Rear Pinion Yoke Help!

I recently had a bolt break off on my rear axle pinion yoke and need to replace the yoke. My jeep is a 91' YJ wrangler with an np-231 transfer case. What trucks/jeeps can I pull a pinion yoke off of to match this one? And can I use the front axle yoke as a temporary fix tell I can get another one? I’m strapped for cash.

Needs to be the exact one. Also get a crush sleeve. It may be better to get the broken bolt out. The yoke needs to be Installed correctly which is about 20 INCH pounds of rotational torque. If its not done correctly the pinion bearings will fail costing much more then having it done professionally.

Taking the yoke off resets the backlash and changes all the wear pattern of the ring gear to pinion contact surface. I highly recommend you not attempt this yourself. Improperly installing the yoke can result in injury or death.

It's better to take it to a shop to do it or possibly extract the broken bolt with an extractor

Agreed with everyone... I would recommend having it shimmed so you don't have to worry about swapping yokes on a trail..

Ok, since no one answered my question I did the research for everyone else reading. It is 2.98 in. overall height, 3.00 In. overall width. The spline is 26. It also fits these vehicles.
• 88-01 Jeep Cherokee (XJ)
• 91-92 Jeep Comanche (MJ)
• 93-98 Jeep Grand Cherokee (ZJ)
• 87-91 Jeep Grand Wagoneer (SJ)
• 87-89 Jeep J Series
• 87-91 Jeep Wagoneer (SJ)
• 97-06 Jeep Wrangler (TJ)
• 87-95 Jeep Wrangler (YJ)
The front yoke will not work because it is the wrong size.
I do appreciate the comment about the 20 INCH pounds of rotational torque. But taking off the yoke does not reset the backlash and improperly installing a tire can result in injury or death just as well. It’s obvious no matter what job you do, you need to take precautions.
I went to a u pull it and for 10$ I got one off a 98 Grand Cherokee that works great.
