I've just bourght a 2+2 and its been standing for some years. This is my first 2+2, I'm used to an Xtreme!!

I'm hoping to resolve the wobble/ movement in the steering wheel; I've experienced torque steer and wobble at 60mph.

I havent checked the front wheel balance or tracking yet but plan to next week.

Am I right in that this should not be the case?

There is an 1800 Zetec and 15" wheels. 195/45 R15s.

What tyre pressures would you run on for road use?

Interested to hear from more experienced 2+2 owners...
Cheers Mark

Hi Mark.

You're right, you shouldn't be getting wheel wobble, although a tiny (and I do mean tiny) amount is possible on most cars because wheels are normally balanced off the hub.
Getting the front wheels balanced should fix your steering wheel wobble.

As for the torque steer, most front wheel drive cars have a little but it's an acceleration thing, not really a fixed speed thing, so can I assume you mean that it's pulling to one side?
As the car has been standing for a while it may be worth looking for a binding brake (or one not working properly on the other side), front or rear. In the past I have had front calipers binding. Even now, after replacing calipers and bearings, my front left has a little more rolling resistance than my front right, but it doesn't show on the road any more than any other car I've driven.

Can't really help with the tyre pressures as I run 185/60 R14 tyres on mine, but, if it's any help I have 25psi on the fronts and 20psi on the rears.

Hope this is of some use.

Hi Mark,

Got 2 Coupes and a 2+2 in the family garage , along with a Blackjack Avion 3 wheeler;-)

I had a similar thing on my coupe (finishing someone else’s project off) when I first got it fixed up and had to try multiple changes to make it get better.  

If a car has been sitting around outside for a while the bearings can get water in them and rust will set in.  That happened on my son’s coupe, had to replace some bearings when we first got it.  Brakes will seize on or partly on and need to be freed off.  Sometimes a disc can warp due to a partially seized brake calliper rubbing the pad on the disc as it drives, overheating it.  Really an unused car needs more care than a used one and should be thoroughly checked when put back into service after a break off the road.  

But start with the simple things. One of the wheel balance weights had fallen off mine so that helped when it was put right!  Then logically check until you find the answer(s).  

I found that my coupe was a bit of a saga. Brakes were sticking and a (not so!) obvious omission was there were no spigot rings fitted to the alloy wheels so they bolted up in slightly out of true positions and different each time!  The drive shaft bearings where worn and I fitted refurbished driveshafts.   All these things made it better each time, but not right until I checked the front hub runout with a dial gauge and found one was distorted which made the disc wobble - most noticeable when braking.  It was replaced and I ended up fitting the discs back on using the gauge to get the best fit.  It has been fine for years since.  

I now try and make sure each car used used every month at least, winter and summer even though I am now doing very few miles a year.  

On my 2+2 I run R14 but at 26 PSI front and rear seems to work OK.   Good tyre wear patterns and handling. 

Enjoy Quntum’ing.  They are very engaging to drive and each have their own character.  

Best of Luck 

Derek

As well as the other comments, check that there isn't a sheared off screw
sticking out of the hub behind the disk.
There is a small countersunk screw that originally held the discs in place
when you take the wheels off.
These frequently shear off or get drilled out.
Not a problem really, unless the remains of the screw is sticking out and
the disc is refitted with screw hole out of position.

Don't discount the tyres themselves.
I once changed a gearbox on a KA to try and cure a wheel wobble as i thought
i had eliminated everything else.
The wobble was still there.
Then swapped the front and rear tyres over and the wobble disappeared.

Thanks Jim,
I'm off to get the tyres and tracking checked tomorrow...
I'll update on the progress.
Cheers
Mark

We have had issues in the past with cars that have been stood for some time where the tyres have not been 'round' And have had a flat spot where they have been stood!
We have had quite a few 2+2s through QSC now. all have had slight scuttle shake. One had serious wheel wobble that cured with new wheels and tyres

Cheers Rob,
I'll be in contact soon for some other spares.
Do you stock the black headlamp inner Liners as a separate part or are they integral to the bonnet?
Cheers
Mark

Hi Mark. 
They are normally 'glassed in' but we can supply them for you, not a problem .
Regards rob
