3.3TT Suddenly pulling left and right

[CBordies]

Hello all,

I need some help, I recently hit a pot hole and blew out a tire. It was about time for some new tires anyway so I replaced my tires (All 4) and had a four wheel alignment performed. After everything was done, I'm noticing that when I get on the throttle it pulls left and when I get off of it it pulls right. Enough to need to make a good compensation on the wheel. Now when I maintain a certain speed, she drives straight. I'm wondering if its something wrong with the differential but I'm honestly not sure. I've checked my air pressures and they are all dead even and the alignment is within spec. Any advice would be greatly appreciated. Thanks in advance. If all else fails, off to the dealership.

My last alignment was “perfect” and yet car drove like shit. Pulling everywhere.

After a second alignment. Was corrected.

try realignment again.

Okay, ill swing by the shop and ask them to take another look at it. I just thought it was strange that the car was doing pull when accelerating and decelerating

This is happening to me as well. @StungBlueGT2 has reported this as well in another post.

This is where I start to suspect that ECS is maybe not as cool as it sounds. Is it possible that a solid "thwack" to the suspension can cause the sensors to no longer accurately "send" information from the suspension? So the ECS receives bad input and sends correspondingly bad throttle and brake output.

I'm rocking the base GT, so no ECS for me.

@CBordies , took my car into the shop today after almost crashing it and found that the upper control arm on the rear left suspension was completely disconnected. The car's behavior became drastically worse today on the way home from work. It must have been loosening previously. Please have them check and torque all suspension bolts if you are still experiencing the problem. It will be very hard to drive if it comes loose at speed.

I’m also experiencing this after hitting a pothole. Whichever way the road is graded, my car wants to drift that direction (low side of the road). I’ve had two shops look at the alignment and tell me it’s spot on. But the car won’t track straight, it always wants to drift and needs constant correction.

What I experienced wasn't a drift as much it was the rear of the car steering itself. It honestly felt like I had an improperly loaded trailer going side to side behind my car dragging the car side to side with it.

Interesting

@ GTAjay - Get the tires checked, or swap front left for right yourself - could be a broken belt (I had a couple in my last car with 40 profile tires) but I suspect you would also have extra noise, but it's a cheap test ;-)

unfortunately the same behaviour occurs with both winter and summer setups.

That rules that out then :-(

My experience on Stinger since day 1 it is very reactive to road camber. Whichever side the drainage goes it drifts that direction. I felt this is inherent for this car model and is not a defect. Find a level road and you should be able to drive hands free for couple of hundred meters without the need for correction. It is amplified on models that comes with the variable rack. Pretty common on cars with variable racks.

Just make sure it’s not due to Tyre radial pull, uneven wear, Tyre pressure and alignment. Just my opinion.

I would agree with you but I have kept very careful about any pot holes but had the new car checked for alignment before I purchased it. No potholes and 3 Aligments later they are checking the veering left and right with engineers.
Thank you

Guys, any solutions? I've been recently also experiencing the pulls - usually to the left and sometimes to the right.

A few days back I was driving with a pretty steady speed (50 mph) when suddenly I drove through a crack on the road (wouldn't call it a pothole, something really minor, yet noticeable) and the car immediately started pulling to the left.

I can add also that the pulls started when I put on winter tyres (brand-new ones)

?

^^Start with getting the alignment checked and suspension for any bent components.

If there's no pulling with the none winter tires, i'd still have the alignment checked out. Could be off and the summer tires have already worn into the alignment. Or could just be a bad set of tires. Swap L/R, does the pull change?

Hey boss,

I am going through the exact same thing right now with my stinger. When i gas it, it pulls left, and as soon as i let go, it pulls right, resulting in swerving on the road. Did you hear back any news on the problem? How did you fix it if you did so?

 

[Oss]

any luck fixing the issue ? I'm going through the exact same thing

Hey all. Yep that is a common problem with the horsepower and the crank rotation under high torque. It pulls the car in that direction and when off the gas is an abrupt release of torque which feels like a pull in the opposite direction.

To correct this behavior you have to over compensate the front wheel alignment with a toe in. I will follow up with my exact alignment measurements that corrected the pulls if anyone is interested? Just know this will add an uneven wear on the outside of your tires. Since you can’t rotate 4 tires because of staggered front/back size, when you do rotate left to right front tires it doesn’t help the wear.
