Is this hydro steering arm length ok?

I'm mounting up the full hydro ram on my front D60. The best place I have for it(considering everything else that's mounted) is directly behind the tie rod. This is the only place I can mount the ram in this position without hitting the tie rod at full lock. There isn't room to move the ram back and mount it directly to the tie rod. Is this enough distance from the kingpin? Will it create too much pressure on the kingpin since the distance from the pivot is so short? Thanks for any help

The longer the lever the easier it will be to turn the tires. If that ram will push hard enough it should turn fine. However the closer your mount is to that kingpin the more shear you have on it, as in your force is not necessarily being used for rotation. No mechanical engineer here just my .02 from some basic statics. Good luck.

(You've got me wondering about that weld on the tab there to mount the ram does it have any penetration? Just a concern)

I bet that is too close... I use a short steering arm, but thst is way short.
The king pin will be under a bunch of lateral pressure, and
the steering would be about 1 turn lock to lock.

You need to move something to make it work...happens all the time.

The closer you get to the kingpin, the less the ram is effectively rotating the knuckle - your knuckle is going to see a LOT of force pushing it straight sideways. Move something.

I haven't done hydro before, but I would imagine it would be way too close to the king pin. Sort of like trying to open a door by pushing on the hinge side, if you know what I mean. Not enough leverage, you are really just pushing on the hinges. IMO, running it behind the axle might be a good idea in your application. Maybe you should get the Rockstomper, double steering arms. This way you can run the tie rod in front w/ ram behind the axle, or vice versa. Just an idea.

Yep, thanks guys. I guess I knew the answer already just getting tired of changing everything because it wasn't right the first time.
I know what you mean about the weld
I was actually burning it very hot and got really deep penetration. But, I'm still not perfect and sometimes it piles up when I don't move at the right speed.

Guess I'm gonna chop off the mounts and move it to the tie rod.
