Ive got a HMMWV tie rod end mixed in with my other parts and will be using it in my steering setup. It has the 7/8-18 TPI to match my other chevy 1 ton TREs, but it is reliefed like a draglink/pitman arm TRE in front of the threads instead of a straight shank into the TRE body.

I have 3 TREs right now including this one and need to buy one more. If this TRE will handle the angles, I want to use it at my pitman arm and Ill pick up a standard TRE for the other end of the drag link.

I think it will work considering the angle of the steering linkage from the idler arm to the knuckle on the HMMWV, but i thought it would be a good idea to ask the actual Hummer owners. Plus its been a few years since I worked on HMMWVs and am going on memory, which as memory serves, it not all that reliable :D

It's relief'd in order to allow all the centers to be the same length and minimize wear on the ball. If you want to know if it's strong enough, I've lifted the entire front of my truck on one wheel by cranking the wheel. The front has 80% of the weight. I'm a good bit lighter than an H1 (5500#), but their extra weight tends to be farther back. If it meets the movement requirements, I'd say use it.

I know it will be strong enough. Its a 1-1/4 ton vehicle as opposed to a 3/4 ton rig that the rest of the TREs came from. Im wondering about the actual range of motion of the ball.

A normal 3/4 ton TRE doesnt have quite the range of motion as the TRE at the pitman arm here's a pic

The H1 TRE is relieved in a similar fashion. Also, the steering links are at an angle on the H1 given the high clearance steering/diff setup. These links have a decent angle on them and could be comparable to a 1 ton steering setup in a high steer fashion on a dana 44 or 60.

Im sure this thing will be plenty strong, but I do not want to possibly damage the TRE thinking it will have a larger range of motion than it actually does. I want to use this TRE at my pitman arm(its LH thread), and then just buy a normal RH thread TRE to use at my high steer arm.
