I'm thinking this was most prevalent from 91 to 96.

I know it happened to a ****load of the XJs we sold to the Forest Service.

 

Shifting the manual with the throttle wide open did break my passenger side bolts. With luck, the old bolts back out with fingers/pliers. However, if you drill them with a REVERSE drill bit, that may back out with that process. Or, once you have drilled them, you can use an EZ-Out or other extractor.

This is easier said than done. Good luck - this will test your craftsmanship.

 

If I owned a 91 to 96, I would flat-out check those bolts.

 

Something odd.

I checked the catalogs and found that the 91-93 have different part numbers than the 94-99 (6034989) and that for the 00 & 01 the number changed to 6036176AA but the description of these bolts and the 94-99 are the same, i.e., .375-16X1.125. The 00-01 mount bracket part numbers are the same as earlier brackets (99). Go figure.

I wonder if the 00-01 bolts were made of a different material/different strength?

Edit: Looking up the bolts on a Mopar site, the part number 6034989 was not superseded by 6036176AA, so something did change with the 00-01 bolts.

 

So should I get a 99-01 bolt as it may be stronger? Or keep it in the 95 range?

 

If the has bolt any threads sticking out you can always weld a nut to it, let it cool & then take a wrench to it.

You can thank my Dad for that trick.

Happy Fathers Day.

 

sadly i haven't learned to weld yet.

 

The 94-99 bolts are the same part number (6034989). 00 & 01 bolt part numbers changed and it is unknown, to me, what changed so you should stick with bolts for your model year.

 

Follow 5-90's advice as I posted it and you'll be just fine.

 

I just had this same thing happen to me last friday, Motors setting on it side now. Getting ready to pull the brokens bolts out today. death wobble sucks

 

My question is would the bolts be differant for a 98 block in a 92? thats my current set up. i'm in the current process of fixing my death wobble, i wont still the thread. When the bolts broke i think it screwed up the tranny mount as well. Good thread made it easy to look for the problem.

 

Bolts are too long and the threaded area is too short. Read what 5-90 said.

 

put on a brown dog 6 hole mount on.the new motor mount is badass.

 

bolts are oem size. just dont put grade 8 bolts in you will never get them out if you shear off motor mount. this happened to me 3 times trust me if your keepin your jeep go with upgraded mounts. itll save your rig pain down the road

 

yeah, i couldnt get a drill in spot to do that and without pull motor out i was able to get one out and went with aftermarket hd mount. i tried, but my idea to go to grade 8 bolts was dumb. oem bolts are 6 i think but grade 8 isnt stronger just harder which makes them more brittle and hard to drill into.
