Let's talk tie rod ends. A buddy and I both have similar JKU builds on 1 tons, we both utilize offset TRE's in the stock TRE knuckle hole on a 99-04 SD60 housing. Offsets were used to keep the tie rod off the diff cover as the real estate is tight there. My rig has 3000ish street miles on it, and 14ish wheeling days on it. His has 500ish street miles and the same wheeling time. Last wheeling trip we both snapped off a driverside TRE where the shank meets the body. 2 different scenarios, but both the same failure. That has led me down the rat hole of looking for a different option. We all know the offset TRE quality is shit to say the least, so that's part of the problem. We could go to a normal TRE, like the ES201R/20102, ES2234R, etc., however that is still a 7/8" shank. Looked at a few other options with Super duty stuff but the shank required too large of a tie rod (1 3/8" shank), or it wasn't cost effective to get tube adapters or threading done (1.0"-16LH thread). That led me to find the ES2062R TRE. This is actually an 85-99 Chevy/GM P30/3500 TRE. Looks to be the same taper at 1.5" per ft, it just uses a larger diameter 3/4" nut, .783 - .905 on the taper diamaters vs the 5/8" nut, .675 - .776 of the normal "1 ton" stuff. These are 1"-16 RH thread only, vs the 7/8"-18 RH/LH options as well. Anyone utilized these particular TRE's by chance? I can tell you physically they look much beefier, and much stronger appearing than the normal 7/8" stuff that everyone runs.

The shank are ties into the body much better on these ES2062R versus the normal "1 ton" ES2010R/L pictured below.

Side by side comparison, the picture doesn't do it justice, as they ES2062R is significantly larger. Seems like this would be a significant upgrade, over the 7/8" stuff, not much added cost, and all parts are readily available. Only real downside is that both sides are RH, but we generally set the toe once and forget about it unless you are compensating for a bent tie rod later now.

On another good note, jam nuts and tube adapters are available off the shelf for there, or you can also buy 1.5" .281" wall DOM tubing. This leaves .938" ID, and a 1"-16 tap requires a 15/16" or .9375" hole. You should be able to tap these yourself theoretically. Obviously not near as good as single pointing it, but definitely doable.
 
No real opinion on the joints but i have questions about your setup and busting the rod ends.

What diff cover do you have? Super duty housings stick out further for some dumbass reason and use a shallower cover to keep the tierod out of the cover on a stock setup.

Stupidly obvious but you did cycle the knuckles to make sure you are actually clearing the cover with the offsets?

Using the Ruffstuff SD60 specific cover. Offset's clear with no problem at all. I run a 1.75" .250" wall tie rod, with straight ends it may clear with less than 1/8" of clearance (Will prove this soon). The other issue that causes though is giving me minimal room for the ram due to the lack of room between the trackbar mount, trackbar itself, and the tie rod. I believe i can make it work though, and that's the next thing on the to do list for the rig.

Now, to be fair and clear I only use a 6.75" stroke cylinder. My axle doesn't quite make it to the mechanical stops on the knuckles when going lock to lock. Had I drilled the arm a little further back, I could have gotten a bit more steering out of it, however the tires would be all into the frame and grill during uptravel travel at steering lock. Also any added steering would for sure cause significant interference with the tie rod and diff cover itself. As is, at full lock, full stuff my tire will just slightly catch the frame rail on the back, and just miss the grill, and with the offsets there is no diff cover interference at all. That's with full width 99-04 housing, ~4" BS wheels, and 1.5" wheel spacers.
 
Have you looked at any of the Synergy TREs? Synergy Super Duty Replacement Tie Rod Ends

Several are 1" -14 shank and are a direct bolt in to the knuckle. They also sell double adjuster ends the just weld into tube and I'm pretty sure they are going to start selling pinch bolt forgings soon also.
 
I used to make .250 and .375 wall 4130 heat treated tie rods. In my rig I ran the 7/8-18 tie rod ends, with as minimal stickout as possible. Back then they were ORD HD tierod ends. Not sure who made them for ORD though. The new ones they have look pretty trick. I would slam those tierods against everything. I'd bend it clear to the diff cover. Set the whole front of the truck on it. Never broke a tie rod end. Probably wheeled the same set of those for 5 years.

I have looked at several Super duty specific options. Only issue is I already reamed the knuckles out for the Chevy taper to begin with, so I can go back to the SD taper on them. Easy enough to change knuckles though ( I have 2 spare sets), however I would need to have the passenger side machined again in order to get the steering arm back. All doable obviously, just a little more work/cost.

I actually have about 8 different TRE options sitting on the bench right now I've been working through, these ES2062R just seem to be the best looking option that I have had my hands on so far.
 
What brand/manufacturer have you been using for the prior offset TRE? Just standard parts store, MOOG kinda stuff? If you're already set up for 7/8" and think you can get away with a non-offset TRE, maybe it's worth trying a higher quality option. The ORD ones mentioned above may get you enough strength.

All of the offset ones are non name brand, no quality manufacturer offers an offset that I am aware of. My current tie rod is already bent, needs to be replaced, so I have to build a new one regardless.

I'm going to ream out a spare knuckle today to verify that these TRE's are indeed the same 1.5" per ft / 7* taper as the normal off the shelf GM stuff.
 
Taper is in fact the same as the typical “1 ton” GM offerings. It is deeper than the other options, but it works. Reamed out a spare 99-04 Super duty knuckle, and it works great. Definitely another option for what should be a stronger off the shelf TRE. I'll add some pics next time I'm in the garage.

For comparison, these are the general offerings traditionally used in the GM 1.5" per ft / 7* taper.

ES2010R/L and ES2234R, both are 7/8"-18 thread, .675" - .776" taper diameter and .81" taper length (1.496" per ft), and 5/8"-18 threads on the retaining nut. These are the normal tie rod ones.

ES2026R and ES2027L, both are 7/8"-18 thread, a larger .715" -.795" taper diameter, and still the same 5/8"-18 thread on retaining nut. These are normally used for Drag link ends.

Option I'm using now is ES2062R, 1"-16 thread, even larger .783" -.905" taper diameter and .93" taper length (1.57" per ft), and a 3/4"-16 thread on the retaining nut.

These numbers vary by a slight bit across different manufacturers, reference numbers are Moog numbers.

Side by side the 2062R is much larger, significantly more material in the joint itself, and should be a huge improvement in strength. 1.0-16" tube adapters, jam nuts, and taps are all available off the shelf, and this particular TRE is stocked in most auto parts stores. It may not be for everyone, and surely not the strongest option available, but it is an option for those looking to add a little more beef to their steering setup using off the shelf everyday parts.

I use GM 1 ton TREs in a T setup and clear the diff cover on my 99-04 no problem. It's tight but it clears.

When I was building it I could find virtually nothing about if this would have worked out.

I just drilled the knuckles straight and used a tapered insert.
 
All I think about is I've ran those GM "! ton TREs" for years, I have broken everything an bent a few of them, but never snapped one.
I wonder what changed.

I'll be honest, a regular style one is probably fine, I think our issue was the offset ones, and the fact that they are junk. That being said, I want to upgrade everything that fails in some way, so here I am lol.
 
what diff cover is that? That comes into play here as well. Right now I have a ruffstuff SD specific cover, and a 1 3/4" OD tie rod, with a straight TRE there will be contact in some amount for sure. Im intending to go to 1 1/2" .281 wall and hope for the best, that buys me 1/8" at least, not much but its something. Going to explore diff cover changes and/or mods to help create a little more space as well.
 
Not sure about that.

It's a standard D60 high pinion cover that came on it. Very tight at full lock but still has space. It also only gets that close right at the end of the steering travel as that Ackerman angle really pulls it in close.

I bet if I was running some super tall tires and had my steering stops turned out a bit it wouldn't even be an issue.

I'm running 35s on stock wheels with a Waggy pitman arm so I get full travel.
