I wasn't referring to the angle, you said you replaced all the tre's, on the draglink is one that can only be replaced by a "NEW" draglink!

Oh. Yea. It was replaced. I figured sence it is also a tre that’s what I’d call it. But the funny part about today is I’m just the neighborhood jeep mechanic for me and my buddy’s. He’s got a 93 xj with a starting issue and his keyless antenna in the headliner cought fire this morning. I have to replace a belt ( ate a rib off) on mine and replace my cracked exhaust header because when I tack welded it I made the air turbulent and not it runs at full rich. I get 4 mpg with my striker now and it lobes and idles bad.

If you've got cracks in the frame you need to fix them "good" ! Then get a "steel" steering box mount, a "good" bumper that has full tie-in's. I also suggest something like a trackbar or steering brace.

When you get some time, tell us the specs on your stroker build and the issues in another thread!

Are these brackets custom built or store bought?

I’ll do an update on the stroker when I rebuild it. Again. First rebuild was because a cam gear. Second was a bad wrist pin and I didn’t wanna chance it. This time it’s bottom end making my noise. Just an excuse to put a bigger cam in. It’s currently .060 over, mild cam, head worked over buy a reputable local, 4.0 rode, 258 crank and the auto.

I would do a tape measure alignment for toe. See if that solves anything.
When I lifted my MJ, the cure was using my ironman4x4 tie rod. Stock is basically a toothpick.
I meow have WJ 30 under it with better steering and brakes.

It's a set I cut out for my last bumper!

[blakews2217]

Well. False positive. Welded and added a stiffener and it is worse. But I hear something that sounds like a hammer hitting the driver side floor when it wobbles. Also, it’s harsh. Like it is almost impossible to hold on to. It also dives right when it wobbles.

Not to state the obvious, bur if you have not, id suggest to have a friend sit in the jeep and cycle the suspension lock to lock as you look very closely under the Jeep. The slightest part moving ever so slightly, can cause major issues. I found this out many times offroad, would have my girlfriend hope in the seat (BABE KEEP IT IN PARK &#129315 and bam, would easily find the issue i couldnt see otherwise.

Is the track bar tight at the unibody end?

Sorry for letting this go dead. I had other issues come up. It still wobbles. I had done that many a times to see the lose parts. The trackbar is indeed tight on both ends. I’ll revisit the UCA on the driver side because it makes noise when it wobbles and I feelnit I’m the floor. Possable bushing didn’t make it all the way in? Maybe I’ll jack it up and set it on stands and push and pull and see what’s loose. I just wanna say thanks to everyone who’s involved here. This thing has me scratching my head.

As has been mentioned before- you're not wasting money, you're resetting the maintenance clock on all this stuff.

That said- EVERYTHING on the front end that moves needs to be replaced if you aren't seeing anything moving when you steer lock to lock.

I had this same problem on the wife's ZJ last year. I forklifted it everything in the front end that slides, rotates, or pivots (except for brake pads, calipers, R&P and those associated bearings) was replaced-

control arms with bushings
steering- from the draglink sttachment to the pitman, to the TREs at the wheels
wheel (hub) bearings
axle shaft ujoints
driveshaft ujoints
balljoints

And the problem went completely away.

Did you look at your steering box spacer? Bet it's broken too.

That list is pretty much what I am doing to my current XJ that I'm also converting from 2WD to 4WD. It's low miles (105K), the last one I had was a 97 that I ran from 92K to 220K, redid the front end as you described and it ran straight and smooth the whole time. Last time was a 2" budget boost, this time is a 4" RE lift. Good stuff.

I hear you. I'm in the process of doing the same to my son's 97 XJ now... and while I'll rehabbing my 90, I'll wind up doing all of this as well, just so when the darn thing is done, it's ready to go. Though cheap, I'm sick of paying insurance and tags on a vehicle that's just sitting there killing my grass.

One thing that doesn't come up very often in DW threads is motor mounts. While bad motor mounts themselves don't necessarily cause DW, they can make a small shake a lot worse. The motor is after all the majority of the mass being tossed back and forth.

This video does a great job of showing this. Notice the opposite motion of the engine and axle...
