    Hi all,

    What are my options as far as rebuilding the steering on my 77 FJ40? This thing takes a lot of effort to keep it going in strait line and it looks that most of the slop comes from the box itself. I would like to stay as stock as possible.

    Thanks, Doron

    Have you adjusted it?

    The only adjustment is for the preload on the sector shaft. It is not adjustable to compensate for wear or slop and over tightening the preload adjustment only makes it feel like there is less slop because the wheel is harder to turn.

    You can have it rebuild by replacing the three sector shaft bushings and the gaskets and seals. The bushings need to be reamed to the correct diameter after they are pressed in.

    Alternatively, you might start thinking about power steering.

    The sector shaft becomes loose or sloppy with wear and the preload must be reset. If the sector shaft is loose it translates to sloppy steering. The proper procedures are in the Toyota manual. While you are in the manual check out the other adjustments for the steering system. Most importantly the draglink and bellcrank.
