    lets talk steering geometry: castor woes and a box/pressure problem

    1, the easier problem: hydro steer box and pump from wto; 2 return ports on the box for a hydroboost truck. keep blowing return lines before my cooler. what kind of pressure is supposed to be in the return line? please dont tell me my cooler is blocked

    2, what is optimal castor angle for a trail only truck? and why? i wanna shim my schizzle 6-8* to correct for a clocked t-case. that will bring it to 2-0* castor angle.

    thanks guys

    Not sure about your first question but the second question i think i can help you with.

    Caster angle is anywhere from 6*-11* on most factory vehicles. The less you have the less your tires will return to center when you make a turn. You will have to use your hands to make your turn and also to return the wheels back to a straight position. The less caster angle you have the worse it is going to be to drive and handle.

    thanks, im really trying to figure this out for a trail only truck. hopefully the ram will help overcome the toughness

    yunit hooked me up off the bbs

    from a website
    i think that answers all my questions.... 8* here i come
    easier steering, but my camber thrust angle will be a little more perpendicular to the road... there goes the high speed cornering :D

    all im saying is that the 8* shim is awfully far. It looks like it will take you all the way to 0*caster. i think you could go 4-5* and see the benefits on the driveshaft and in the steering in a nice compromise.

    Stupid question time...
    Have you talked to WTO about this?
    My first impulse would be to say "blocked or restricted cooler", but you said not to say that... so I won't.
    Having NOT said that, are any of the flexible return lines bent really tightly, or any hard lines kinked or dented? There's obviously a restriction in the return circuit somewhere...

    see.... everything worked fine untill i put the new pump/ box on. so all the lines are the same, and so is the cooler. so i've ruled out a blockage... unless some giant hunk of crap came outta the box and into the lines.
    and there doesnt appear to be any bent lines
    calling them isnt a half bad idea :cool1:

    If you increased the flow through the cooler (which happens when you add a ram to the system) then any restriction in there before will be much more evident. If the hose is blowing off before the cooler, then that is a big red flag that the cooler is clogged somehow, it just wasn't bad enough before with the amount of flow going through it. Basic hydraulic principle, more flow with same restriction = higher pressure before the restriction, thus blown lines.

    Sorry, I assumed since you put a hydro steer box on you also installed a ram. I still think your cooler is the problem from the way you describe things, but without seeing your setup in person and the operating conditions when it happens it is hard to say.

    To answer one of your earlier questions, the return side should have no pressure except the little that is created from restriction of lines and fittings and such.
