I've just posted 3 photos of the OEM Steering Stabilizer (or Damper, or
Shock Absorber), and a sketch of the mounting bracket which is usually
removed when installing an aftermarket gadget like the "Safety Steer".

Bob Burkitt had the foresight to make those photos and the sketch in case
anyone needed them, and provided to me for posting.

Thanks Ken I removed the old spring loaded shock today and have an Auto Zone replacement coming in Tues. (tomorrow). The factory shock mounting ears are still on the frame but were pounded down to make clearance for the bolted on bracket of new shock. Hopefully the ears can be bent back into position if not I'll make new one.

Are we talking about the device used to keep the GMC from wandering on road ruts? Or at least make it easier to travel the rutted roadway.?

I had thought it was to take strain off of the steering gear and to help control the vehicle from any wandering if the steering gear has a bit of play ( steering wheel able to move 1 to 3" before the wheels respond to movement.

I had seen such devices and thought they might be a good idea if they worked.

What is the intention of the shock mounted device used for? The same thing or does it soften blows from road bumps?

Isn't it true, shocks only control movement in one direction? that would make 2 shocks needed to do any good??

Maybe we need to buy big off road tires and make the GMC's 4x4's.

Larry, shocks can and normally do dampen motion in either direction. On a suspension shock they can provide different damping in either direction and they can do so at different velocities. In the case of the steering damper, it is the same in both directions and is meant to reduce road induced shocks back through the steering system--mainly to the pitman arm. Sometimes, pitman arm loads can be so high that it will actually break the arm. Increased caster can dramatically increase road shocks and pitman arm loads.

Look to the rear, for wind steer. Check the wear in your bogie pins and
bushings, condition of your shocks, and rear alignment. Also check the
tracking of your forward facing bogies, particularly on the passenger side.

First go drive, I mean sail, a Class C, then drive your GMC.

My GMC does push a little with a crosswind, but not much, a class C, esp and older one is terrifying.

IF your GMC is that affected by cross wind, you definitely have suspension wear like James Says.


can you feel the Semi push hit the rear and push it over, or does it happen as the semi is closer to the front. That info will help narrow the trouble area down.


On my C I could feel the semi pass, it pushed the rear over, then the middle, then the front, it was quite the Hula dance, maybe a chacha ?

Keith, the semis are as the truck passes the front if memory serves.
The semis are annoying but not troublesome
It's the Gusty winds that are a problem.

I've never driven a class c but I imagine it isn't fun haha.

GM used the damper on the E cars from which our front end is derived. It is there for a reason. They can fail in several modes. The leak mode is obvious from an outside glance. Internally they can fail in several ways. I had one that looked perfect but had 1/2" slop (a huge amount in linkage movement) before it damped. Apparently the internals had started to unscrew. You must take the unit out of circuit at least on one side to test it.

Steering stabilizer is only for road shock (potholes, etc,) Check your tires for cupping type of wear and proper load range/inflation. If you are getting pushed excessively, either there is too much slack in your running gear (entire suspension system) or you are losing your grip on the road surface. If the tires are not aligned close enough, they are scrubbing/slipping on the surface already and so your grip is already compromised. If they are overinflated, grip will also be reduced.

Those loose bogies in the back don't even have to be that loose. The
forward-facing will scrub unless perfect, which it never is, and flex as it
does so.

If we have any money left over for a project next year, it will be a rear
disk and reaction rod kit from Manny. And I will include the tracking
devices for the front bogies. I'm thinking that will make the biggest
difference with wind push.

G'day,

I had occasion to chat with Dave today about some other items and I asked him about the Steering Stabilizer; he advised that he no
longer makes them.

He suggested that you go through the steering system piece by piece to determine if every part was serviceable; see:
http://www.gmceast.com/technical/Mueller_Steering_Inspection_Guide.pdf

He noted that setting the steering box on center as per Alex Ferrara is important. (I can't find the link to his procedure).

He also noted that getting the most amount of caster into the front end by installing offset bushings in the rear of the upper
control arms would help: http://www.gmcmidwestclassics.org/Web%20pages/align.htm

Finally the parts of the front suspension should be checked, ball joints, control arm bushings, shocks, etc.

Thanks Rob, I appreciate you asking.
Looks like a full front end cleaning and servicing is in order along with the rear.
