Ok, so after my last case had a bent main shaft i ended up buying a used case from a junkyard, it seems to be rebuilt but 3 of the 6 bolts to mount it on the transmission are missing i can take the ones out of my old transfer case, but i am unsure how to do it without messing them up. is there an easier way. i tried to do using vice grips one but it was difficult getting it all the way in. when i couldnt get it farther in with vice grips i used the nut and a socket but it ended up messing the nut up when it got to the end of the threads. luckily i have extra bolts and can buy extra nuts but i need to get this done by the end of the weekend. Any help is appreciated.

[EDIT] - the case is a 231 AMC

 

A simple way to install studs is to use two plain nuts. Run one nut on the stud then run the other nut up to it then tighten it down on the first nut. Put a wrench on the top nut (only) and drive the stud home.

Used this technique over the years without using a commercial stud driver.

Used this technique to install two studs on my TC.

 

Thank you so much, i wish id thought of that. i could have had this done a couple days ago lol, i was scared i would mess it up.

 

ok, so ive tried that. but when the studs get about half way in both nutes start turning and the stud wont go in any farther. could it be due to dirty threads on the case? ive tried cleaning them out, but i dont have breakparts cleaner atm. the best i could find in my jeep was pb blaster. should i just go out and buy some breakparts cleaner tomorrow? or could it be the threads werent lined up right. i did my best to line them up.

 

You're sure they're the same length as the ones you took out? Sill question I know, but things may vary from year to year. I haven't had the pleasure of trying to remove the bolts you are trying to conquer so I'm not sure. Can anyone chime in on this?

 

Get some good cleaner and make sure the threads in the TC are clean. If you cross threaded the stud it would show up right away. It sounds/looks like the internal threads are full of crap. Use an open end wrench to hold the bottom nut and use a box end wrench to turn the top nut simultaniously as you turn the stud in. You may have to do this all the way in. Measure the extension of the existing studs and use this measurement so you know when to stop inserting the new studs.

Like BillyBoy asked, are these the correct studs? You said you have extra "Bolts".

 

They are the studs from my transfercase i took out, the cases are both 231 amc, i dont know the year of the one i am putting it. but yeah i need to buy some cleaner and do that. i will measure the studs and the holes.

 

I forgot to mention this, but it helps to put a split lock washer between the two nuts.

 

What year is your XJ?

What does the data plate on the TC say the model is?

It's odd, but the parts catalogs back to 1988 call for metric studs: M10X1.54X36mm. I installed SAE studs from the hardware store in my 1999 NV242J with no problem. The studs from your existing TC should work okay in that replacement TC, but make sure the threads are apples to apples, i.e., metric to metric.

 

pretty sure its just because the threads are dirty. its an 89 cherokee.
