Steering wheel shimmy.
Bob Hobden
etc, new radiator, I also fitted a new steering damper as the old one looked
rather tired ( probably original).
Having completed the work I took it for a drive and everything seemed
excellent, the steering was improved with no wandering on bumps etc and felt
altogether smoother somehow. Came back checked everything was well (oil,
water) so went for a longer drive, on the way back, turning a 90� RH corner,
the wheel suddenly started to shimmer alarmingly, if I'd have been on a
motorcycle I'd have called it a Tank Slapper, from then it did it even on a
slight bend.
I did have some shimmy at speed before but put that down to a wheel out of
balance as that's exactly what it felt like, this problem now is worse when
any lock is applied and came on suddenly.
Anyone any idea what's happened?

Swivel pre-load, bushes gone west, steering damper bushes not put on
right, or damper not a good one .. could even be damper mounting come
adrift ... ;)

manual doesn't say which. That said, as it was a sudden fault could that be
a likely problem, I would have thought it's more like something has failed.

You remove them.

Thanks. If there's two choices I'll always do the wrong one first. :-(

the other thing to check is the UJs in the steering column.
Be aware that I've been working on and off on this problem on my Rangie
since I've had it, and it's still not completely fixed. It's often a
combination of all the things...

There is some slack in the steering, always has been, so I will check that
out (when I get some time and the rain stops). It's the sudden nature of the
fault that has me perplexed, one moment I thought how improved things were

I seriously wonder if the new gas Britpart steering damper has failed
suddenly, probably coupled with an existing pre-load problem that the
steering damper hid. (or buckled wheels, or out of balance wheels even)

Don't take it to heart, it's just the Land Rover re-asserting it's
dominance over you (it's supposed owner) :-)

The damper is the thing that made most difference here, took off an
apparently-OK one (not leaking) and fitted a better (as in "felt stiffer
when moved) second hand one.
thye various other things also helped, it went from going into a harmonic
oscillation which could only be cured by dropping below 50 mph to a shudder
which dies out quickly, before doing the damper.
The steering column bit with the 2 UJs and the spline thing is neither too
pricey nor hard to replace. I'll put a new damper on it (rather than an SH
one) sometime, see what that does.

Harmonic oscillation is exactly what it felt like and just as you say,
dropping the speed down (below 40mph) removes the shimmy. So I'll take a
long hard look at the new damper and then go through the whole steering
system. Unfortunately on my test drive I took all the old bits from my
recent renovations, including the old damper, to the dump so can't refit to
see if it cures the problem.
In all this I forgot to mention my 90 has OE power steering, must have been
a posh one when new. :-)

Took off the new Damper and it doesn't seem to be working properly, there is
resistance to movement but it isn't consistent and sometimes it pushes in or
out without any resistance for a small distance. Will have to speak to
Paddocks tomorrow.
The steering column does not appear to have any slack in it at all although
there is some play at the wheel, can that be adjusted on a Gemmer power
steering system? Looking at the manual it mentions adjustments but I can't
find where it says what does what and how to adjust things.
I'll have to do the pre-load ASAP and see if that helps.

It's very subtle.
Marge is on her second steering column top UJ in a year. I fitted
Britpart previously, and it lasted less than six months. The failure was
still a miniscule amount of play, but it gave a lot of wandering around
when driving.
Our local specialist has two ex-MOT testers in the workshop, and one of
them showed me how to spot it: with the engine off and the steering
unlocked wiggle the wheel back and forth very slightly and quite fast,
feeling for any 'clicky' movement. Get an assistant to do same whilst
you rest a finger either side of the UJ on the column itself - if
there's any give you should feel it move differently, and you might hear
an audible click. The first one that failed clicked, the second didn't.
She's now got an OEM UJ fitted, and so far all is well.

that appears to work properly with no harmonic wobble showing up in the
steering. All I have to do now is return the naff damper for a refund.
Knowing my luck they will probably say there is nothing wrong with it.
