You said "the part from the servo to tie rods" There is only a linkage rod there between the steering servo and the servo saver. What is coming loose? You have the servo horn which is the part thats screwed onto the servo itself. Then it has a linkage rod connected between the horn and the steering servo. When you say bellcrank are you talking about the servo saver which is tied into the front steering assembly? It's the part with the adjustment wheel on it. If it's set too loose the wheels will not turn. You'll see the servo push the linkage rod to the servo saver, but then the servo saver will not turn the steering linkage. If you can post a pic of what is coming loose.

the servo saver, allows the servo to turn without turning the wheels when the wheels are stuck against something or when the wheels recieve an impact.

There is a thumb adjustment on it....screw it down and the servo saver is tightened. if its to far up, (unscrewed) then the servo will turn without the movement transfered to the wheels.

Then there is the servo horn. sometimes the splines on either the servo's output or on the inside of the servo horn can become stripped. no matter how hard you tighten the screw that holds on the servo horn, it wont put the power of the servo to the servo horn....thus wheels wont turn.

Sometimes the way the steering linkage is set up it binds on the adjustment knob and actually loosens it as you turn. Also there should be a through bolt that goes from the bottom of the chassis thru the servo saver with a nut on top. This seems to be where your problem might be. It should tighten down without binding the servo saver. It sounds like it's too tight and causing the servo saver adjustment knob to loosen up when it turns.

here are some pics of my servo saver from my Tornado. Looking in the manual they look smilar. Is it possible your adjustment knob is missing a washer between the top plate and the knob itself? Does it look like yours is setup like mine? Take it apart and look at it real good. I bet you figure it out once you start trying to get it back together again.

thats the exact same set up on mine,  so your saying im missing the washer??   if so im sure i can find one at work or in my tool box at the shop
 im a bodyman so im sure i have a washer,     its frustrating to me becasue i never had to deal with some many issues on a rc truck before
   i just want to go racing, or some bashing  and i cant because its always breaking on me

did you figure it out? I was thinking if it's too tight it will want to loosen when steering.

I wish I could do more to help.  The only thing I can think of is something is binding in the servo saver assembly itself to make the thumbwheel adjuster move.  Have you tried disassembling it yet?  I wouldn't be surprised if something was missing, maybe a spacer or washer? The top plate should have something between it and the movable link so that it does not bind.

i switched to a spektrum reciever and it came with a servo a strong servo, the servo saver is moving freely, nothing binding up 
 so i guess ill break down the steering linkage and see what happens
  or is there a different bell crank  that is compatable with the red cat

I thought the original problem was the servo saver adjustment wheel kept loosening causing the steering to not work? It sounds like now your saying it wouldn't turn because it was too tight, but now a stronger servo is making it turn? Do I have that right? If that's the case, remove the servo linkage from the steering linkage and turn it by hand. Something has been snugged up too much which is probablly binding the steering linkage. Or is the servo saver adjustment wheel too tight now? Make sure you find the bind. You don't want to burn up your new servo.
