That's not abnormal for any car actually. It only happens at full lock. It's caused by the front tires not being pointed in the correct direction for the arc they're on. There's nothing that can be done about it. It's a rather lengthy and involved explanation as to all the in's and out's about how the steering geometry works and why.

You could go to an independent alignment and insure that the wheels are aligned correctly. They will insure that the alignment is correct while going straight. The sharper you turn the wheel, the more incorrect the wheels will be. That's not usually a problem. At 'racing' speed, the inside tire is barely touching the ground and it doesn't matter what direction it points. At normal speeds, you're not turning sharp enough for this to be an issue. It isn't until parking lot speeds that the wheels get turned so sharp they can hop.

Some cars have the steering lock adjusted so the tires can't turn so sharp that they start hopping. This isn't the other steering lock that prevents a thief from steering your car without a key.

Some cars have been designed in such a way that the wheels won't get off-arc enough to hop. But, they drive like crap at speed in the canyons. It's a trade off. I prefer the better handling at speed and seldom experience the parking lot hop anyway. My 4C has this hop. Some call it the racer's hop. lol

 

Thanks very much for that, makes perfect sense. As you say, driving on normal roads its perfect and only manifests itself on sharp parking turns or similar. Thanks again :laugh::laugh:

 

Happens quite badly on Ferraris also. As RacerZ said, it's a function of the steering geometry. Remember many of the Giulia team came from Ferrari.

 

Thanks for that, I'll take the homage to Ferrari as a positive trait >>

 

Enzo Ferarri work for Alfa Romeo long before he started his own company, Ferarri. Enzo was a race driver for AR, then ran the racing development section at AR. Eventually, a differance of opinion led to Enzo leaving AR and starting Ferarri.

That's always a question of wonder for me when people talk about Ferarri vs Alfa Romeo and who helped who. Currently, Fiat owns both Alfa and Ferarri. Parent & child? or siblings? Ahh, just one big happy family with all the normal problems.

 

and then Ferruccio Lamborghini who was building tractors at the time bought a Ferrari and complained to Enzo about the clutch and gearbox, decided to modify it with one of his gearboxes and Lamborghini 350 GTV was born

after the 1973 oil crisis, and slump in sales, Chrysler took control of Lamborghini

one of those Italian blokey rivalry things, "your gearbox is ****" ... "well see if you can do any better" LoL

maybe they both missed the steering issue ;-)

 

Yup I can confirm both. My Miata also has it and was just aligned last month after my frame work. I got it close myself, but it needs to go on the machine to dial in the proper toe. Feels great now under normal conditions, just like old times.

 

I also have this but already at half lock by my QV sometimes. At my 4C its coming only at full lock. But the grip in curves is really much better as in 4 C.

 

Hey Dave,

That was the very issue which brought me to the forum. I took mine to the dealer and they provided a service announcement. Turns out it's a feature!

Cheers

Andy

 

LMAO

Who wrote that? Marketing? Only marketing can turn a mistake/oversight into a "feature".

Actually, it's an acceptable compromise. A but of wheel hop, only at very slow speed, only at full lock and much much better handling at speed in the twisties. Or, remove the hop and remove the better handling. Tough call really.

 

pitfall of being down under

i have to turn the screen sideways to read anything

 

LOL can assure you that's a forum bug!

 

Yes! Alfa Link. And yes this steering set up IS used on most sports cars. The new virtual axle and tall double wishbone set up of the Alfa Link is brand new, proprietary and will make Alfa Romeo very competitive in the sporty small and mid size sector. I spent a few hours at work yesterday researching this. There are only two published pictures of front and rear suspension for the Giulia. If any of you are working on your cars and have the wheels off, please take a pic and post it. The Ackerman angle can be thought of as a controlled drift of one of the front wheels with the actual goal of reducing understeer and not promoting it. Interesting, and if you look at a traditional sports car front end, being turned to full lock, you can see the Ackerman angle appear about half way past center and then out to full lock.

Cardinal sin of mixing Apple and windows! Thx for switching. Anyone that's reading in bed can enjoy mine

No dont think the pressure will do anything it's more mechanical imo. Kind of feels like its rubbing against the wheel arch and sticking but its not

 

just so long as engine failure isn't a 'feature' i'll live with it

 

So on the Quadrifoglio this scrubbing is actually worse than it is on a 458 or 430. Doesn't bother me, but my wife was freaked out by it. Just warn anyone who drives your car for the first time.

 

997 is the same

 

I always thought this was a function of the double wishbone front suspension/steering geometry....
Funny though, this car has some of the quickest steering I have ever had the pleasure of driving....really something special...I like the light direct steering of the Quad...one of its best points

 

Hi i have just read the post, i have a question as would be great if anyone could help me? i am in the UK

I swearing wheel on giulia was slightly pulling to the left the car is only 6 months old and done about 8000 miles but today i took into into a tyre garage to get all the wheel tracking/alinement the front they managed to get alined just in the recommended alinement, but they rear left if 4ml out and they could not adjust this anymore and the bolt where they aline it could not turn anymore, the tyre garage said this could be down to a faulty bush? from the factory? is the a massive issue that i should take up with the alfa dealership as in is this a fault? or is this the way the car is designed??

I have read the above comments and my wheels also feel like that when i am on full lock

Thanks!!!

 

You should consult with your dealer on this. If the alignment can not be adjusted to what AR recommends, there is a warranty issue. Let them sort out what's at fault and what the solution is.

Just in case you don't already know, the front only has a toe adjustment, while the rear has a camber & toe adjustment.

 

I hear this sound at much less than full lock, as well. Only when I am navigating a parking spot, really. I figured it was just another "quirk".

 

For those in colder and wetter climates. I swapped the Pirelli Corsa Assimetrico's for a set of Ultra High performance 3 season tires, Michelin Pilot Sport AS 3+. Living in Seattle where it rains for about 6 or 7 months and is about 50 F or 10C through that time period, these tires are great in the wet, handle and perform beautifully and have eliminated the steering lock grinding. I will put the Pirelli's on from May to end of September an probably get an extra year or two of wear out of them and hopefully have the best of both worlds.

 

Wonderful! Thank you very much jwq2!

Now I wonder where is the best place to locate a jack stand when lifting from the jack point? I tried the knuckle/hub when I had mine off for the Forza controller install but it didn't seem very stable or safe. I ended up blocking the whole thing at the control arm mounts. Hmm maybe on that new beefy crossmember corner?

 

Get a Jackpoint Jackstand and use the same point for both. Apparently very popular, I've been on the waiting list for 12 weeks now. ETA 2-3 weeks for me.

 

Yeah, I guess the under panel may have to come off, even then, I would want to use some rags or some cushioning on the cradles.

 

Question for those who also have a Stelvio or have spent a good amount of time in one: Does its steering make similar sounds? I'm asking because my wife is considering one and will probably find it very concerning. She thinks the front wheels are about to fall off of my Giulia and doesn't accept "Ackerman angle" as an explanation.

 

We have a QV and a Stelvio. The only difference I've noticed is with the tires. In the colder weather it does feel like the fronts about to fall off with the pirellis...no such feeling with the stelvio. Also on sharp turns into driveways the stelvio handles much better than the QV...I've actually gotten stuck before in the QV on our sons school entrance....never in the stelvio. Fwiw, my wife can't stop praising the stelvio...and she's pretty picky.

 

If you got Summer tires, they actually have a lower temperature limit typically around the 40f mark. Summer tires and cold weather don't play well and you'll hear a skipping of a tire sound if they're not warm. You'll also get the bonus of uneven tire wear and possibly void of warranty depending on the brand.

 

My Giulia seems to be making as much steering noise on Sottozeros as on its original Pirellis. I don't remember that from last year.

 

Hi
Can you tell me if these Michelin tyres are run flats?
I have Goodyear, and they are terrible when it’s cold.
When I am trying to park they make a thumbing noise.
Many thanks
Kev

 

That thumping noise is not a result of the tire. It's a result of having the wheel at full lock while parking. No matter what tires you have, it will thump while parking.

The thumping is due to the high performance design of the steering and/or suspension design. It's a compromise, of sorts. It can be tuned out, but then you loose the high performance in the canyons and other winding roads. Since it only happens while at full lock, while parking, it's a small price to pay for superior handing at speed (IMO).
