Hi -- forgot to x-post here, not much activity in the trucks group:
I've got an opportunity to pick up a 1990 F-150 Extended Cab
4x4, and the rivet in the crossmember behind the steering box has
loose, allowing for a visible amount of lateral movement when someone
moves the steering wheel side-to-side.
A cursory look has ruled out any major cracks at box mounting points,
and the web has provided a fair amount of material regarding this
fix. It'll certainly be tightened up by punching this rivet out and
replacing with an oversize bolt, that's familiar territory to
me......but is that all I can do? Surely that single rivet can't
all the movement in check.....anybody's experience in this matter
would be greatly appreciated.
Thanks -- Jon
Just for reference:
Loose rivits were a known occurance on that vintage. The
OEM rivits in my 90 and 93 were both replaced under warranty
with hardened bolts. You may also consider replacing the
strut (radius arm) bracket rivits with bolts if it still has
rivits there. BTW, those need to be damn good bolts and
tight. There was a TSB on the subject. Sorry, I no longer
Where are the strut brackets? (what is a radius arm)?
I have a 1990 F150 standard pickup, I guess I'll have to check on
these, if this is a common problem. It's always good to know about
problems that are common to certain makes and models.
By the way, why not just weld them??????
One other thing, someone in this thread mentioned a truck group.
Where is that?

Radius arms for front axles attach to outboard sides of
frame. The strut bushings also seem to have a life much
shorter than expected. It can become very noisy on rough
roads and may dart or pull to one side or the other when the
brakes are applied. The right side is much more likely to
deteriorate because of it's close proximity to the cat which
tends to cook it. I was rather pleasantly surprised by the
improvement in driving quality after I replaced a set that
should have been OK with the polyurathane bushings. I have
no problem doing this kind of repair my self with a
collection of air tools and equipment I have assembled over
the years. Strut bushing replacement is not a bad job at
all if you have a good set of tall jack stands, a good floor
jack and a good air impact wrench with a couple of sockets.
At my age, air power is a necessity to do some of these
things. In my younger days, I used testosterone instead of
Thanks for the info and opinions -- the photo link is related to the
aforementioned TSB. The amount of twisting movement visible at the
swaybar bushing (1/4-3/8") had me crawling all over the truck, trying
to see what was permitting the movement.
Sure enough...a crack has propagated along a factory weld at the
leading vertical edge of the crossmember/frame junction...so it's the
chicken/egg affair, whether a loosened rivet was a symptom or the
cause of the problem.
