Late Model steering play
Posted by: jgalfo ()
Date: November 18, 2020 04:31PM

how much is normal, is there an adjustment for this in the steering box?
my steering wheel can turn about 1.5 inches before the front wheels respond, is this normal or something that can be adjusted out? before you ask I checked the tie rod ends and they have no play, what else should I be looking into?

all help appreciated

The pitman arm bushing at the drag link is often the cause of steering slop. The idler arm can also make slop (should not move up and down at all only rotates). The box is adjustable to a point. Instructions are in the GM Corvair shop manuals. 1 1/2" play is not an exceptional amount of slop for Corvair steering but I have seen many with less slop than that. Worth checking things out and trying adjustment.

Access to the lash adjusting screw is via removing the round plastic grommet at front edge of driver's side inner fender in the trunk.

Warning: If the top of the adjusting screw is even with the lock nut, the box has already been "over adjusted".

Look at the bushing before you mess with the adjustment. Have someone turn the steering wheel while you look for play.

True. Pitman arm bushings deteriorate over time.

You probably have no clue how long the current bushing has been in use. From memory, I have probably replaced it every 60,000 - 70,000 miles.

I always use the nylon bushing and my cars have no noticeable play when the steering box is good also. Some people say the nylon transfers too much shock but most cars have solid joints there.
