With the first trys I had this problem.
These have space to rim, not much but enough.

I ordered 3/8" heim joints, weld in bungs, lock nuts, spacers, and tubing from QS components in Indiana for about $120.00. Enough to make all four tie rods and the front steering rod. I also had to purchase bushings, grade 5 fine thread 3/8" bolts and nylock nuts (I went with fine thread because the nuts work great for wheel lug nuts also). I then made tapered bushings to bush the tapered holes in knuckles and turnbuckles to straight 3/8" holes. No permanent modification to any original parts. All went together great and the mule drives like new...probably better.

I looked back in my phone photos and found a few. Wasn't planning on a tutorial, just a few to remind me later of what I did. Here are a few of what I used and how the joints compare in size to the original tie rod end. I bought the spacers thinking I would need them for clearance but ended up not using them.

Good looking parts, I'm sure in the near future I will be needing new tie rods.

Here a some pics of the bushings I used and the primitive jig I made to turn them. I pulled a tie rod end apart and matched the taper on my mini lathe. Used a 3/8" shouldered bolt and an all-thread connector nut to chuck it up in my lathe. Center drilled the bolt head for a live center to hold it true. I turned the bolt head down a few thousandths undersized (at selected taper) for clearance.

I turned the bushings long so there was enough material to fit to each individual tapered hole. The bushings were installed and tapped into place lightly to seat them in the taper. A die grinder with an abrasive pad was used to easily remove the extra bushing material for a perfect fit in each individual hole. The old tie rod assemblies were measured center to center of tie rods and the tubing was cut and bungs welded in with my little 110v mig. Couldn't find any pics of finished product or my notes on measurements but that's pretty self explanatory...they need to be the same length as your old assemblies (center to center) while in the middle of their adjustment travel. Easy peasy....about 3 hours and $150 and your mule will drive like a dream!!

QS Components had these ends listed under "panhard bar kits". I was initially concerned about the strength of these since they are only 3/8". They have a listed load rating of 7,605 lbs. each and I've been running on my mule for the last year and a half without issue..including hauling heaping loads of ammo and people in and out of KCR.

Very interesting post! I have a couple of questions; I assume you ordered DOM tubing from QS Components to make your new tie rods, do you remember the size and wall thickness you used? Do you happen to remember the taper angle you turned on the sleeves?
Thanks again for posting, this is a very good solution for replacing some very hard to find parts.

Yes, DOM tubing from QS. If I remember correctly it was .750 OD x .058 wall. As far as the taper angle goes I believe it was 2 degrees. I set it directly from an old tie rod because the shape of the tie rod made it very difficult to measure. My cheap little Chinese lathe has degree markings on the cross slide but they don't appear evenly spaced so I don't trust them, but it did indicate very close to 2 degrees.

Thank you for the reply. I think this may be a project for this winter. Original ends are almost impossible to find, and expensive if you do!

Does something like this help solve the problem. Most automotive tie rods are about 7 degrees and there is lots of different size tie rods to choose from.

I suppose there are lots of solutions. I had three priorities in mind when trying to come up with a solution.
1. No modifications to original parts. No original parts were modified, original tie rods could be replaced in minutes. Reaming the steering hubs to accommodate a different rod end would/could significantly decrease the strength of the attachment point, where adding a bushing would only strengthen it.
2. Affordability. About $150 total to do all five tie rod assemblies. Replacement heim joints are about $6/ea.
3. Easily accessible replacement parts. Heim joints are used extensively in racing and hot rod circles. Many different manufacturers and most are standardized sizes/threads. Shouldn't have any issues finding replacements and you don't have to have the specific application (i.e. Right outer tie rod end for a 1980 chevy chevette) to find the correct one in the future.

Any suggestions for size and source(s) for dust boots for the original tie-rod ends?

Contact me via e-mail. I have them in stock. Ones for the later style O&S or the early style found on the M274 having zirk fittings.
