Well I'm somewhat stumped as I could not find anything obvious over the weekend with the pry bar. TRE's seem fine. I did not put a wrench on the steering arm bolts but visually they looked good and I did tighten them back up post CM12. I guess I need to pull the wheels and do a complete inspection on jack stands this weekend.

Its still hard for me to accept I may have overheated the brakes. After many trips with an un-braked trailer behind me I have never got them hot. A casual trip to Silverton should not have worked them that hard.

I had a serious DW issue last year. Turned out to be loose spring ubolt nuts. I found them when I was tearing it apart to put shims in, because I thought that might have been the problem. Added the shims and tightened the nuts down good and no problems since. Sometimes it's the simple things.

Or a combination of simple things that add up. Ever wonder why troops break march over bridges?
Good reminder to tighten mine as part of the troubleshooting. Mine have been loose in the past, and I'm pretty sure that creaking I get in the front end under flex is related to that.

Well this might explain a few things. Bad phone pic but the LCA hanger is cracked to the point of 90wt leaking out.

And discovering this on your birthday none the less! Ouch! Think its repairable?

I think to determine if I can weld this back together would require complete disassembly. I don't think I want to tear it down to that point without a housing on hand for re-assembly. I don't have the garage space for long term storage of an immobile vehicle.

So I thought about this and I am sending a spare box (cardinal's actually... I hope he approves) off to west texas offroad to get rebuilt. They get good reviews on mud and I am thinking maybe I might be missing something in the steering box. I'll get it back in a few weeks and put it in the 60 and see if there is any improvement.

I feel like I have checked everything on my rig. I even actually put two power steering gear boxes on it, one good used one not rebuilt by me or anybody.. Some had slop and the rebuilt ones didn't. Still they all had a "pulsing" feeling when turning slowly. I think that may be contributing. Also, just FYI I have been through 3 power steering pumps seeing if it was that. none made a change, but my super fancy one from PSC groaned really loudly and I replaced it with a NAPA one after sending it back to PSC twice with no improvement.

It's back! My trip to Moab last month was sketchy at best. I hit a diagonal expansion joint coming through Vail that nearly tossed me into the guardrail.
Truck is now down until I can rebuild a number of systems, not the least of which is replacing the lift. (I did a knuckle job, apparently wasn't the full problem)

My springs are now severly sagged on the driver side and I suspect that is pushing the truck out of alignment enough that I'm wearing my tires oddly. Couple that with spent bushings (likely) and you might have an explanation for the DW.

So, what springs to get? I really wanted to pop the 80 arms under there and put some coilovers in, but I think I have talked myself out of it.

OME- I have had OME leafs on a 40 before. Not bad, but not too much lift, and they sagged quickly IIRC. Also stupid expensive now for some reason.
BDS- I had these on my otherwise stock 60. Rode like garbage, even after years of use.
OME coils- Had these on my 80. Not impressed. I think progressives would have been better. In general, I think OME is set up for mild heavy trucks.

What I do: 90% is daily driver to Boulder and back. 10% expo style wheeling with just a little crawling mixed in. Nothing too extreme but my current lift has ZERO rear articulation and rode like crap to boot. Only heavily loaded did it ever smooth out.

Mods: I have a PTO up front, a diesel, and a hardtop, all running on 33's. Nothing too crazy. Ideally, smooth ride with some whoop travel would be nice.

Thoughts? (Retire it and buy an 04 taco you say? lol)

I found a loose pitman arm, loose knuckle studs on one side, and one wheel bearing was slightly loose. My guess is that several years of pounding the truck on these Maze trips has taken its toll on the hardware.

I thought I had it all fixed, but the problem was still there. At highway speeds, I would hit a bump and it felt like a tire was out of balance for a second or two after. Not a huge deal, but weird. I took the truck by Robbie one day at lunch and in about 5 minutes he diagnosed shot TRE and trunion bearings. Funny part is that the TRE's were replaced 5 years ago or so.

On the ride home that day, I watched a Cherokee nearly wipe out on the interstate from this problem. Bump and then violent wheel shakes and he barely kept it under control to pull over. Friday on the way back from the Boulder, the same thing happened to me. Had to nearly clean my shorts after that experience!

All that said, I will be planning a full on knuckle rebuild along with a lot of other stuff that's overdue.

The tech part of this, is has anyone else with five five five TRE's had similar early failure of these parts? I think the main problem I'm feeling right now is more TRE than trunion, but it all has to go.
Just to clarify, you had not replaced trunion bearings before experiencing the death wobble?
