Here are the finished hydro assist pics.  I made a new bracket for the top of the diff.  It's made out of 2"x 2" x 3/16".  I tried to place the ram as perfectly in line with the tie rod as possible to try and get rid of the ram rotating the tie rod.  I also tried to get it as close to keep the leverage factor down on the bracket welded to the tie rod.




Backside of mount on top of the diff



As close and as parallel as possible.  Close enough that I have to undo the passenger side hiem from the steering arm to get the bolt in and out of the diff bracket. 



It makes slight contact at full steer L&R.  I have a new bolt with the head half shaved off to replace it.



Frontside of diff bracket to show the radius cut to fit the curve of the housing.



I just used the TG tie rod bracket I had bought from the first time I installed the assist.  I cut it down and just welded it to the tie rod rather than having it on a clamp.



Another shot of the tie rod bracket.

Your set up looks nice. Great pictures. I am gonna have to figure out how to do basically what you did and integrate a track bar bracket. When I complete I will post pics.

Volcom, how close do your ram hoses come to the oil pan on compression? Looks pretty tight...I know mine is...I actually have a couple small (clearanced) dents on the pan from the fittings on the ram lines

When bleeding the box do you crack the bleeder while turning the wheels lock to lock till its just fulid comming out or just turn it lock to lock then crack the bleeder for a sec then do it again similar to brakes?

I think they come close but they don't touch.  They might touch if both front springs compressed at the same time to the bumpstops (aka jumping :)  ) but I haven't ran the truck that hard yet.  If it becomes a problem, I can rotate the ram so the lines are pointed toward the rear.

Steers great on the road.  I don't notice the over steer.  It makes mine streetable.  Without hydro assist, my death wobble is so bad, I can hardly drive it.

i have heard alot about people complaining about it steering weird on the road. but that is as far as it goes... only heard... i am yet to drive a rig with hydro assist. but i am not scared. haha. on my truck i dont run a stabilizer or anything and all i have is a pull to the left but i am sure that when i set uo the rear springs i have, i was a little off on my hangar placement. :( (one of the rear hangars is at a greater angle than the other one) I think that being able to steer over anything with your pinky finger is well worth it.

Thought I would bump this for my own question....

I have just finished hooking everything up and i am in the process of bleeding everything. I seem to either not know what i am doing or i just dont know what i am doing

info on set up--4.3l, saginaw pump, toy ifs box, 6" stroke ram

When the truck is in the air the ram will not move until i go all the way to lock, this is turning either direction.

With tires on the ground the ram moves immediately but the rest of the steering will not move until the ram has maxed out its stroke.

I have been going back and forth with the steering wheel both engine running and not, also tires in the air and on the ground. I have continuously bleed the box and air comes out on the occasion.

Does any of this sound familiar to when any of you bleed your box? Sny better tips on getting this working properly? (or whatever normal is if you care to explain)

When bleeding the system all the parts should be connected. Is the ram attached at both ends? If not it should be.

Mine did the same thing.  Ram wouldn't move until steering when to lock.  Sounds like you still have air in the system.  Let it sit and try again.  You might also have to remove a hose (or both hoses) from the ram and manually fill the ram with some fluid.  It takes awhile to get that ram full of fluid.  My fluid would also have a ton of bubbles in it.  I would let it sit for 30 minutes and come back and turn it back on and steer back and forth with weight on the frontend.  I repeated that probably 5-6 times.

Help Me here. How is it possible for your ram not to move until you are to full lock. If the ram is attached at the axle and tie rod how could it not move together with the steering?

Wow, I didn't prefill anything and the first time I hooked it up, it bleed within an hour.  2nd time (after fixing a broken ram) wasn't as fast but still got it done.

Yeah both the steering and the ram should move at roughly the same speed.  Like the name applies, the ram is assisting the PS box.  When you have the motor on, can you take the cap to the reservoir?  Can you see a ton of bubbles in the fluid while the engine is running?  Once you see bubbles, shut the motor off and let them dissapear.  Also, I had to rev the engine higher than idle to get the air out.  Hopefully you can get it figured out.  I'm just trying to throw out some ideas??

Your ram isn't hooked up to the axle or tie rod yet?  You might try hooking it up and having the tie rod basically move the ram in and out to help get that air out.

did you do anything other than just run the truck and let the air work its way out?

Exactly. The ram should be attached at both ends or you are wasting your time.

When you hook it up, make sure you get it centered along with the steering box centered.  You don't want to bottom out your PS box and still have ram travel.  Something will go boom.

It wont move with the tires in the air until i get to lock. I will try to center it by hand

i pre filled my ram and lines hooked it up and let it hang and it worked great right out of the shoot. I bet you still have some air in there. do you have is going through a cooler? i also pre filled my cooler and cooler lines as well

I have a cooler and the lines get warm when the truck is running, I didnt prefill those though
