I'm removing my transfer case drop kit. Anybody know the length of the OEM bolts that bolt the crossmember to the "frame"? I'm guessing I'll need shorter bolts. Maybe not? it's a 1" drop kit the PO had installed.


Thanks
 
Thanks. Was hoping to have them before I started with the off chance that somebody knew.
 
I don’t see why you need shorter. There’s nothing inside the “frame” they will run into. Just gonna stick inside the frame an extra inch than stock.
 
One more question...should I loosen the motor mounts before I do this and then tighten them back down after the Tcase is bolted back to the 'frame'?
 
I doubt the PO did it when the drop was installed but if you want to do it to “square” everything up I guess it wouldn’t hurt.
 
@cufor98 i guess as long as your getting to the motor mounts depending on the miles it may be worth changing them out for piece of mind. What motor is in it? 4.0? And also if you stiffen up the MM make sure you change the trans mount too as the 3 all work in conjunction.

Thanks for the tip. It's a 4.7. 129k miles.

Not for sure about that motor all I have ever ran is the 4.0 XJ’s and a couple 5.2’s in my ZJ’s. All I know is motor mounts are something that often get overlooked but play a major role and take a beating especially in an off-road rig.

Unless they aren't like most standard hardware, 1-1/2" length bolts and longer aren't threaded the whole length. Before you get started, I'd back one off a few turns to make sure the threads go all the way up to the head. If so, then you're good and don't need shorter bolts.

Touché good sir, I guess I didn’t think of this.

I've gotten myself in a bind (literally sometimes...lol) with having incorrect hardware for some applications...figured I might pass some follies off as experience/help!
 
Guess it wouldn’t be too bad to back one of the bolts out a little and should be able to determine the amount of threads and go from there without getting too committed
 
10-4. Thanks fellas. I thought about thread length as I've been screwed on that before too. I haven't had a chance to look yet.
