I have an 87 3/4 ton 4x4 Silverado with power steering. I have to turn
the steering wheel about 1/4 of a complete revolution before the wheels
are affected. The steering gearbox must have an adjustment but, there
is little to no useful information in my Haynes manual.
Any help will be appreciated. Thanks.
Move the wheel in the free play area and have some one look at the pitman
movement on the gear box, if none ,some adjustment can be made, but usually
not that much. The pitman shaft adjustment is on the top of the gear box,
this can be tricky because an over adjustment can cause a lack or
you'll also want to look at the steering coupler (rag joint).. after
20 years it could be worn to the point of hitting the safety stops to
turn the steering box. that's what happening on my '88, but I've just
not gotten around to pulling the shaft and replacing the rubber disc.
Ok, the steering coupler looks very good (I should mention that I have
not owned this truck long). Any improvement that can be made would be
great. The play in the steering allows these back country roads to
direct the wheels anywhere the road sees fit. The only thing that looks
like an adjustment on the steering gearbox is a nut and bolt in the
middle of a small plate on the top. If this is the adjustment, I assume
that I back the nut off and drive the bolt. However, what do I drive
that bolt with? I didn't see a slot for a screw driver.
I have not had an alignment yet. When I replaced the tie rod ends, I
carefully measured and matched the distance from the center of the
insertion bolt to the tie rod itself. I was very accurate but still
wanted to eventually have a pro alignment. Would that effect steering
slop? Don't laugh but, what is a drag link?
A drag link is the HD tie rod looking thing going from the pitman arm on the
bottom of the steering box to the steering arm attached to the left steering
...and yes, too much toe-in would feel like steering slop and too much
toe-out would make the truck wander.

An alignment is a good idea. They will find and report problems that
affect the steering and those problems need repairs BEFORE the wheels
can be aligned.
This can be money well spent. Saving the money can prove often to be
If none of the steering items are worn, I would replace the gear box. A
good used one from a salvage yard should not cost more then $50 at most.
You can get a good rebuilt unit from Lee Manufactoring.
Also look and see if the shaft coming out of the bottom of the steering box
that the pitman arm is mounted to (sector shaft) if it is rocking in the
bushing on the bottom of the box. We have one of our trucks that has a lot
of play in that...
