Hydro Assist Threads

So dumb question.

Are you not moving the arms up?

 

[mr jits]

Not a dumb question at all.
If, a high steer kit is needed, I'll go that route. I think that there will be enough room if I'm attaching the ram in the rear (which also counters the forces in the front as LT pointed out), that I'll be able to do the install without interfering with anything. It may take some creativity in fabbing up a mount, but I'll deal with that as I'm planning.

Mr. Curmudgeon Rice has the ability to lathe the threads for the 80 series tie rod ends. He did it for our 80 series and for my FJ40.

 

[Delancy]

I can't seem to visualize the aft mounted ram.

 

[mr jits]

Rice is already on board for the rods.
I'll take some pics over the weekend and do some p-shop to give a visual of what I'm thinking.

I can't seem to visualize the aft mounted ram.

Just picture the ram mounted on the back side of the axle housing and the tie rod. Just like the front, only flipped around. That's my plan anyway.

Edit: apparently this was covered...

 

[ThreeEyedBandit]

Please do, and good to hear from you! I'd love to see what you come up with. What I have in mind is going to be very simple and straight forward. No high steer arms or anything crazy.

Good to hear from you too! Sounds like we might have the same plan. I've already made and installed some heavy .250" wall steering links, and next will be the ram mount and R&P. I'll keep you updated as this comes along.

The tie rod remaining in the OE location, not relocated to the top of the knuckle, right?

Guess I never considered this as an option, and reason for confusion. Apologies.

Imagine the mount I posted up earlier attached the tie rod behind the axle

Look at post #22&23

Yup! You got it now. Stock arms and tie rod location behind the axle. No worries, glad the idea clicked for you.

Post 22 relocated, if I'm not mistaking.














Post 23










Not seeing how the angle isn't an issue, but won't clear the arms.

Unless I'm missing the point.

Still don't see how it'll work.

To be remotely close to parallel with the tie rod puts the ram mounted some distance from the axle.

Am I missing something?

Is the angle depicted in post 23 not an issue?

 

[mr jits]

Using heims allows for a few degrees of deflection up and down, and if your angle from the tie-rod is severe, you set up your mounts to adjust for that. Also, would need to have a long enough ram to adjust for the extra throw.
All that aside, I think the ram will be almost parallel to the rod in the back. None of the above should be an issue.

Look at your post #12 on this thread. Imagine that mount behind the axle, same principle just mounted differently in the picture that I was referencing.

 

[Delancy]

Haha. I forgot that we all don't share the same tolerances around the tie rod, the source if my bewilderment, but also realized a double shear high steer may not be possible, either.

It's late and cold here, but preliminary, so hopefully " we" can figure this out.






Also encroaching is the DC joint.

The DC joint is actually my biggest worry for clearance. Out wheeling the other week I noticed my friends front DC joint barely touching the tie rod while climbing an obstacle. It will be a tight fit, but workable.

 

[PKP80]

I have hydro assist on mine

I have it on mine as well on the drag link instead of the tie rod so it works with a factory setup.

 

[Delancy]

This may be the dumbest question in the of mankind, but : flipoff2:

What about attaching the ram to the inner DS arm, being the fixed point, the ram body paralleling the tie rod?

 

[landtank]

the DC end typically bolts to the transfer case. I know Chris has a double DC shaft, is that the case of your friend as well?

 

[LT]

Luke @ 4x4labs already makes a similar steering arm like the 80 series for the FJ40/60 and mini truck axle. Perhaps he can make some custom ones that are designed for the 80 but are bent up higher to clearance the drive shaft issue.

Or you can reverse the ram and have it mounted up by the third member with the ram extended and collapsing to the driver side knuckle.
