Hey guys

I've had an alignment done on my 04 Monaro before Christmas to the specs on the FAQ. On a drive up to Hereford I noticed to the car was pulling to left when on a straight.

Went back to the same place today and many different attempts and some tweaks, it was still pulling left. They had a look at suspension and wheels etc but everything seemed all good. To my knowledge the car hasn't been in an accident and its relatively low miles (43K).

Has anyone experienced anything similar?

I'm heading back there next week for another technician to have a look at it. Any thoughts would be great.

Here is the alignment details after they made some tweaks today.

Make sure your tyres are all in good health, I assume they are the same across the axle? Also make sure tyre pressures are spot on. Otherwise check the brakes are in good health, a slight bind could cause issues.
All that being said, I've always found the camber of our typical roads tends to make cars be more inclined to drift left, I wonder if you're now over thinking it since having the alignment checked?

Reading this with interest as mine has been awful for a couple of months. Thrust angle all sorted now, rear end in the green. Just the front camber is out and i am hoping this is the culprit, just need to find someone who can do it properly for me.

Otherwise, new rear tyres it seems. Fronts replaced just before Christmas.

May I suggest that you find a quite road when you can drive smack in the centre on the crown of road, release grip on steering wheel and car should drive true no pull either way. If OK nothing wrong with set up. Good luck

Jack the car up and check each front wheel for excessive brake drag or a sticking brake calliper.
If that's in order swap the tyres front to rear.
The next step is checking the springs and top mounts for damage as well as all the bushings in the lower control arm for any wear or damage.

could just be the usual crap road that is worn in to furrows , tyre pressure plus make of tyre has an impact too

My CV8 pulls slightly left as well. It was worse though before I had new springs, shocks, top mounts etc fitted - Just a bit annoying TBO.

That's only a very basic check really...and what appears to be their adjusted value...ie the far right ?? of toe at 2.4mm , whether that's in or out is unclear.
But it's also a huge number.

The other window has the same reading in red, so would assume that is the before value ?

Very poor readout though.

But more importantly...was it pulling to the left before, on that same road/route ?

Does it do it everywhere ? Any other changes to the car ?

other effects , lower profile tyres different bigger wheels and tyre pressures , type of tyres kuhmo not good, vredestein much better , worn suspension or standard non worn suspension as it can be vague , plus as above alignment issues , there is a section of road near me it’s like driving in a furrow noticeably worse when i had kuhmo tyres on the car

Every car ive ever had pulls to the left, when driving on the road.

And its not my cars. Its the camber of the road, as lincsls1 said. The better you get the alignment, the more you feel the pull to the left,as when the car is set up well,the effect is pronounced.

Go and drive on a runway,racetrack or dragstrip, and the car wont pull to the left.

Roads are cambered for drainage.

o/p , they have put a LOT of toe in on your front axle, which would counter the steering pulling a bit, but will remove a lot of feel. Id try to go for zero toe on the front on a fast road car.

if i remember correctly when i did the road response pack on my cv8 there was an extra washer on one side , i think it was the nearside , it was on the drag bush ? / radius rod bush , which was there to improve the handling and turn in , so the car is not even set up evenly at the front from the factory

IIRC (and FWIW) when Monkfish fitted road response pacs they set the alignment very, very slightly asymmetric left/right to manage just this issue.
I don't know what settings they used and whether they otherwise differed from standard.

Thanks all, really appreciate all the replies. There's certainly a wealth of knowledge on this forum!

I probably should've included some more details, I didn't want to feel like I was writing an essay XD.

Tyres where all good, pressure, tread and same brand on axles etc.

Before I got the first alignment it was pulling right. Took it to the garage and gave them the alignment details off the FAQ for the CV8. Tech did it and took it for a drive and off I went. Shortly after I was meeting some friends in Herefordshire. Driving up from Cardiff on the straights I noticed it pulling to the left. Called the garage and this is where I am now.

When I went back myself and the technician took it for a drive. They have a nice straight dual lane road nearby. It has slight camber on either side and peeks in the middle. We drove up and down on all parts of the road. Apex, rhd lane, left hand lane etc. Even on the apex and right hand side the car was still pulling slightly left when the wheel was straight.

I've certainly got a lot of points I want to look at, if I get a chance in between work(and its dry . .) I'll check the points raised by mfp.

Suspension wise the car is pretty much stock. My CV8 doesnt have a lot of modes on it . . . Yet! Even tho the car has 43k on it it's 15 years old. So some worn out suspension components probably wouldn't help.

The garage I went to does all sorts of cars. In the garage with my Monaro was a Ford F100, an mx5 track car and a Morgan so they certainly deal with a variety of cars. I'm heading back there on Tuesday so fingers crossed we get somewhere.

Are the tyres quite worn? As the above post alluded to, it can matter if the makes are mixed (although I see the OP said they are the same brand)

Most owners these days (of all makes) don't rotate their wheels, especially since they are more often directional. If possible, You may get a result by switching the wheels front to back (presuming you have the standard same size all round) or across the axle and see if that makes a difference.

i run the monaro tyres at 36 psi and tyre wear is very even
