Check the adjuster on the rack. You might need to knock up a "tool" from a piece of pipe to adjust it, but if that is loose, there will be
significant lash between rack and pinion, causing exactly what you describe.
Or the rack could be worn.
Did you have work done on the rack recently (fitted a quick rack maybe?)

Cheers boss, we had no luck, we knocked up a 21mm allen key but it was tight tight, couldn't move it either way... as it had been peened into
position in three places.
I'll probably end up getting a new pinion & rack to fit into it, not had it to bits since I've had the car, nor recently, so I guess
its just worn! lol

I think it already has one in, it's currently 2.5 turns lock to lock, which I believe is quick?
Something that I noticed whilst driving on the m1 cruising at say, 70mph, is when I let off throttle to decelerate, the car swerves to the left,
almost the torque of the torqueless engine relaxing, an the weight distribution making a difference?
I think the camber settings that I have don't help straight line things, so in going to reduce the negative camber on each corner a touch

I'd leave the camber as it is now and make the front toe in a bit. That should aid straight line stability. I used to have 3 degs of negative
camber on the front of my Indy without issues. But get the rack sorted first before experimenting with the alignment.

Surprise surprise its back in bits again...
Just nipped down the garage to have a look at the pinion adjustment nut
Whipped the rack off
Bit of a struggle, but managed to undo the pinion adjustment nut
Bearing inside holds the pinion centralised, as the slipper spring holds the tension down onto the rack
No real signs of wear on the teeth of the pinion itself
Nor the rack innards...
So built it all back up again, and its made sod all difference - still loads of play, but only when there is load on it, ie: the car down on the
floor... when in the air, it has no play
I'm thinking the bearing may be shot and needs replacing, as the pinion moves in and out slightly when you go lock to lock, which I'm
pretty sure shouldn't happen...

Problem solved...
Here's the breakdown, kinda difficult to explain.
Removed the rack again, removed the pinion adjuster sleeve, and the circlip and the bearing.
Then removed the plastic 21mm slipper nut, spring and slipper itself.
Not much wear on the Quaife item itself, but all the movement was from in between the bearing and the circlip. I thought when you tighten the pinion
adjustment sleeve up that it'd clamp the bearing nice and tight, it doesn't.
Two ways to cure would be to get a thicker circlip, which would eliminate the play, but it already fills the groove nicely.
So we replaced the bearing just because we could, then put a shim in between the bearing and the circlip which removed all lateral movement.
We followed the Haynes manual in setting it up, but with it being shortened and new innards we took the process principle, but adjusted it by feel.
We put the rack in the car, and put all the steering back on the could adjust the 21mm slipper plug in situ whilst wobbling the steering wheel so
there was next to no movement.
Obviously the tighter you go the more wear on the pinion and rack you will create, it also leads to a heavy steering car. So feels smoother with it
loose, and less gratey but then there is movement.
I've jeopardised the smoothness of the lock to lock transition for a right rack, everyone loves a tight rack, right?

I've now over tightened the slipper slightly, as it no longer self centres, and it makes it incredibly heavy to turn whilst stationary.
That said - I would sooner drive it like this all day long than have the play... but I will be backing it off as much as I can before introducing play
as Seb said above
Feel so planted and solid to drive now
Oh, another thing - laser alignment my arse, didn't think it felt quite right still, so did the tracking with a piece of string, and my drivers
rear was toeing out quite a way, so we tracked it up the old fashion way - this also has made a massive improvement!

No reason whatsoever for these photos, other than the fact I bloody love driving the car in this weather
Brakes work OK...

Well impressed!
It looks so good, and so different from the "taxi" that you started with

Cheers Mr B.
I prefer the look of it now, and will be improved when I get to Stoneleigh on Sunday to pick up some 13" Pro Race 1.2s hopefully!!!

Oh, another little something was to stop my car melting... some real carbon fibre riveted on should stop it, especially with a melting point of 3500
degrees lol

Shame! I was going, but Wife No 3 reminded me that we are going to see Bill Bailey in the evening, and I have to pick up a borrowed trailor for IVA on
Tuesday. Will catch up with you when the MK is road legal, any excuse for a blat

Certainly Dave, then I can drool over your custom made parts and give me ideas to stop me twiddling my thumbs!
See what I mean regarding my nose cone wrapping right under the chassis itself, rather than butting up to it...
Can you foresee this being a problem for what I'd like to do?

The hinge pivot needs to be just behind the bottom of the cone, if you use marine hinges with long legs you can bend them into an L shape. Or fix the
hinge behind the front chassis tube, going down to the cone.

Great read... Just spent my Sunday evening reading your thread.
Very inspirational, always wanted a MK Indy, should be moving into a house with a double garage towards the end of the year so perhaps 2014/15 might
bring one..

Fantastic day out with some great people at Mallory Park today
Car ran completely faultlessly - so a massive thanks to cosmick for his outstanding help getting the car back to the form it is.
A complete transformation from what it was like last year.
Here is a decent video from today, a tussle with a 205 which was great fun, I just didn't have the balls like him to take Gerrards any quicker
on the traction I had...
