I just lifted my xj 3" and I was about to do a flex test and I herd a loud bang from some where up front. I was turning left to get my wheels lined up with a wall I was going to clime . I had it in L4 and it was engaged . When I got out and looked I couldn't find anything wrong well it all looked ok as far as I could tell

Any ideas?

 

Mine did this, ended up being an axle shaft u joint that was worn. It broke the cap and all the needle bearings out. Crawl under and look between the steering knuckles and inspect them good.

 

Ill look today

 

Put a wrench/socket on the track bar bracket to frame bolts and make sure they're not loosening up on you.

 

what year? i have a cad front, its gone bang a couple times cause the shift fork slides off the collar under load and either breaks the fork, or busts the pads off of it.

 

Still vacuum operated?

 

Yes on the vac and its an 85

 

Could be a shift motor issue. Ever considered this?

By the way this only happens in 4 w

 

And it's a stick shift

 

I figured that.

 

Just giving out tidbits at a time, are we?

 

Sorry I only get enough time to get that much out my little helper doesn't let me do much . I lifted my jeep one bolt at a time with a play time between each one took 4hrs to do one set of coils and shocks

 

no. i did the permanent trick, and busted the fork right in half. then after finding a much beefier looking shifter fork in the jy, (i should have taken a pic) i put it all back together like i had it before and all was well for about 6 months or so. then it started popping (read: loud bang) off of the collar when it was in 4wd and i tried to turn. pulled it apart again, used the force (my brain) and rammed a little bushing i machined in there. now its nice and tight with only a few thou of axial movement.
