Wj Upper Control Arm / Death Wobble / 3" IRO

I've got a 3" IRO lift on my 2004 WJ. Had some problems early with death wobble and thought they were solved. Not quite, encountered it twice last week so I'm trying to work through the parts to see what's wrong.

JKS adjustable track bar is tight with no loss of torque from installation/balance/alignment.

TRE's look good, no indication of bad ball joints.

But I found that the drivers side upper control arm bushing looks odd. I would welcome any input if anyone sees anything out of the ordinary with this -- looking at the drivers side upper control arm where it meets the front axle. Looking from front of vehicle.

Thoughts?

Mine looks similar. I'll take a pic and show you. It is amazing however how bad the FUCA bushings can be. I have one out now and will change drivers side as soon as new bushings arrive and I can install one in pass side.

Okay, so I guess that's normal? Or needs to be replaced?

That's normal. I just replaced my upper control arm axle bushings a few weeks ago and I thought the same thing...its just the way it sits in the axle mount above the differential. Just check to see if the rubber bushing is still good and not cracked/split/etc.

Was driver side any easier? I hope to do that one tomorrow. Pass side was a real bugger.

Drivers side was easier for me. I used a sawzall to cut through the metal bushing for both and the drivers side one just popped right out.

Wow! That sounds easy! Just drill and sawzall..... I'll consider that technique as soon as I get the pass side bushing installed. Hopefully this weekend. Darned snow storm .....

Mine at 178k miles were cracked and horrible!! Hard to see until you take arm off. If you hear clunking when hitting bumps and can't find the location.... I'll bet you need them too.

Wj My solution

I finally completed the drivers side... used a homemade "Miller Tool" from a grade 8 8" bolt with washers (get progressively larger washers) and the back side of a ball joint tool.

And a BFH!!

But the tool got it out pretty well, did the same thing on the passenger side, worked well.
