Shock isolated steering column.
#1

I have an idea for a steering column that has precise turn characteristics with no play but isolates the steering wheel from road jolt (fingers crossed). Spoke to Pete at RS Barn about it and I will be sending him some sketches to see what he thinks, could be a good idea for track cars on rough corners. I also have an idea for a replaceable ball joint on the lower arm which can be removed in situ and also height adjustable for lowered cars as that allegedly is a cause of failure on some set ups. Don't throw the kitchen sink at me over that comment, I'm only taking into account what was said on Blaszak.com. If the ball joint idea is good then there would not be any need to do exchange deals on lower arms, ONCE YOUR ARMS ARE MODIFIED to accept the new balljoint assy. Pete was saying that you can't get steering knuckle arms any more but RH ones are available in the UK. Could someone post a closeup of a LH assy please,

assuming that its different.

is this a problem? i have not noticed any unusual amount of shock, vibration, or anything like that at the steering wheel. of course i come from tiny british sports cars, so perhaps i am just a lot more tolerant, but one of the things i actually like about this car is the amount of feedback i get at the wheel. one of the things i had to do was fiddle with the steering to INCREASE the amount of response and feel at the steering wheel, as i thought the stock feel was a bit vague.



but have fun - any project like this can be a real kick

Don't get me wrong, road feel, any slippage of the tyres whatever is okay, that comes from rotational feedback. What I want is to isolate jarring up the column, which will allow minor tweaks such as a delrin steering rack bush for instance. maybe a rose joint at the steering arm con. to the knuckle to increase road feel. But without incurring too many penalties.

I must not be driving hard enough, I don't feel any shock in the steering column?

Try the roads in Scotland then you'll change your mind!

Road bumps like that were, for me, greatly reduced by the chassis brace, but I can see what you mean. On rough stretches it's not the shock that gets me so much as the noise and the radar detector jumping and clattering against the windshield. Very annoying.



Good luck with the development! Anxious to see what you come up with.

Bob YOU are one of the people that has complained about road bumps in another topic elsewhere on the forum, I forget where it was. Steady on the old Cabernet there partner!

Forgot to mention, other parameters for this knuckle joint is that it has to dismantle and be removable without dropping the steering box or messing up the top seal area as the knuckle allegedly needs a bit of pesuasion to come off. Want to get round all that crap.

i complained about road bumps when i installed spherical bearings instead of the OEM upper strut bearings. i fixed that by reinstalling the OEM units. my complaint was about the dash though. i never complained about bumps at the steering wheel. i've never had that problem in this car.

Oh don't be so pendantic, that's my job! I'm going to bite and ask what "fiddling" did you do to the steering. You have mentioned the RSB power pulley before but Pete says it looses effect after low RPM. Anything we should know (please don't say you've already posted it elsewhere, please)?

i have the broadfoot racing power pulley. that's what he sells. the power steering pump has a bleed off, so when it reaches pressure, there is no change. the pulley just delays that.



other than that, and the rack-attack delrin mounting bushing, my steering assembly is OEM. i have huge tires, and spherical bushings, which tend to make every little bump show up, but it does not translate to steering wheel issues.



i think this one is subjective. i come from british sports cars. i hate the way modern cars feel. i like being able to run over a coin and tell you what year it was from the input in the steering wheel. i want to feel it in my arms when i turn the wheel. i hate the vague indeterminate feel of the wheel in cars like a mercedes or bmw. i don't want the wheel jerked out of my hand, but i don't want to be able to move it a millimeter without it moving the wheels, the instant i move it.
