    Hello all,

    Replaced failed ZF steering rack in 1981 245 with used ZF rack from 1986
    model. Splined shafts at bottom universal guarantee same alignment
    compared with failed unit. In straight-ahead position, judging from
    front wheels, steering wheel is 90 degrees our of horizontal. Both
    outboard steering ball joints were installed same number of turns onto
    steering rack rods (10 to 11 turns each side).

    Is there a "hydraulic" centre or neutral position on these ZF racks? If
    yes, i will need to pull the steering wheel and reposition it. If not,
    then the rack rods can be used to adjust the steering wheel to the
    centre position. Which is the correct approach?

    Regards / JCH

    You can pretty much determine the rack's center position by counting
    turns of the steering wheel. Then you should move the steering wheel to
    reflect the rack's center, and only do the fine adjustment (less than
    one spline on the steering wheel position) with the tie rods. Ideally
    the tie rods should be exactly the same length.

    Replace tt with t (twice!) and remove parentheses to email me directly.
