Serious steering issues...Tries to kill me over 40mph!
Ja1983:
Yeas, one of the previous axle had the square bars on the bottom of the swivels, i was wondering if this may help things? (at risk of disturbing the swivels (once touched never seem to be right)
Seems to be doing ok now, havent had any scary experiences since changing the damper.. fingers crossed!
just need to post this knackered one back to paddocks who will send it to britpart to confirm its knackered before they can offer an exchange/refund...
can anyone recommend any good quality steering dampers?

i used to run a procomp damper on my comp truck when it used to get used on road,
as unbalanced mach 5 beadlocks and simex used batter the living day lights out of std dampers.
havent even got one now mind, kept bending them

Sinusoidal would make you think simple harmonic motion, unfortunately it's multiple degree of freedom system so the harmonic pattern could be quite complicated which make the diagnosis (and cure) quite complicated.
If you think of a weight on a spring, the spring stores energy that accelerates the weight as the spring relaxes, then the weight gains height which stores the energy as the weight slows. Energy is continually transfered between stored (potential) and moving (kinetic).
We all get that, right?
Well possibly what happens in the suspension is that there is more than one "spring", each bush, the suspension, the steering with all it's balljoints and the track rods that can flex etc etc.
So what can happen is that energy can be transfered from "spring" to "spring" or to kinetic energy or both, there may be more than one oscillation and they may have more than one freqency.
Stiffeningf the "spring" may also make things worse, nbot better. Dampers on the other hand absorb this energy and turn it into heat. hence they mask the problem and make it manageable.

sounds like you have death wobble very nasty
a friend had this and it was a castor problem
hope you sort it out soon mate
Series 3 Brad:
i had a similar problem on my series, have you checked the shims on the passenger side ball joint? if there is one or more there, take one out, see how it goes, take it from top and bottom....if it has a bottom on a 90. just a thought =D
