04 G35x binding/bucking feeling when turning from a stop.... please help

Postby totchan55 » Thu Dec 18, 2008 6:54 am

I have a 2004 G35x. It feels like the front wheel hubs are binding when I turn the wheel. I mostly feel it when I turn the wheel and then try to accelerate. The car feels like it is binding/bucking. I just got the car, and 3 weeks ago, the Infiniti dealer replaced the front left wheel bearing under warranty, as well as the compression rods. I was only driving the car for 5 days before that, so I'm not sure if it was there before the dealer worked on it. I've felt this before on some 4x4 vehicles when turning, but I thought that the G35x didn't throw power to the front wheels unless necessary, so I didn't know that the hubs would engage without reason. Anyone have any experience with this? Any reply's would be appreciated.

Welcome to NICO.

I'm going to take a few stabs in the dark here. Maybe Steve or one of the other techs can chime in with a more educated analysis.

First try to drive the car in circles (sounds like a joke, I know). If the symptom persists beyond the initial "buck" then I'd say it was transaxle related. If the symptom only happens once, then you're able to drive in a circle without it happening again, I'd say it was a suspension issue and might be something like a shock/spring bearing/sleeve (I haven't looked into how the front suspension is setup on our Gs).

Are you possibly driving in snow mode? I think snow mode automatically starts with a 50:50 torque distribution, then the computer adjust accordingly.

Is it only doing it at heavy acceleration or all kind of? Do you see your slip light blinking when it does it?

This are important questions to see better. It could be too many thing. Could be just worn tires or summer tires and VDC kicks in all the time. Could have been tire pressure. Are you running same size tires all around? Is it only doing it when you turn left or right?

It is called torqe bind. AWD cars will have this if the center diff is not slipping like it is supposed to. Something is keeping it engauged. I replace the valve in Suby auto trans all the time for this proplem.

It is something that needs to be corrected before you damage the center diff.

Thank you all for your replies. Here are the answers to your replies. Maybe you can get a better idea. Sentientbydesign - It persists beyond the initial buck. I actually just checked the receipt. They replaced the hub and the bearing. When I picked it up from the dealer, I felt the bucking. Then I noticed that the snow light was on. I turned it off when I realized it. Never correlated the two. zozoka1212 - The bucking it at acceleration of any kind. Whether I am turning the wheel while doing a K-Turn, or turning out of a driveway. Once or twice the slip light went on. As far as your other questions. Tires are all new. Air pressure was set when the tire pressure light came on, and it does it regardless of whether I turn right or left. (Left hub & bearing replaced)awdjdmtalon - Here's the thing. My bumper - bumper warranty expired 11/30/08. I dropped the car off at the dealer for the compression rods and hub and bearing on 11/28. I am trying to see whether or not this is computer related, or equipment related. If it is drivetrain related, the car is still under the Infiniti drivetrain warranty. But I can't afford to bring it into the dealer to find out if is not covered under warranty and be charged a diagnostic fee. I want to use the information I gather here and make a decision on whether or not it is drivetrain related. I honestly thank all of you for your input. It is definitely greatly appreciated.

Welcome to the Group

The way the ATTESSA system works is when wheel speed variance it engages the elctro-magnetic clutch inside the transfer case.

Under normal driving conditions and accelerating at ~<1/4-1/2 throttle application (depending on input from the steering angle,decel/G, and numerous other sensors) all the torque is applied to the rear wheels and no current is applied to the magnet. Once a variance of somewhere around 2-3 mph between any of the wheels, current is increased to the magnet in accordance to what is needed to regain traction. Most of the time the VDC will momentarily cut throttle control and fuel injector pulse to assist your G in regaining traction.

If your front wheels are turning when they are not supposed to be you may have an issue. This is one of those things you may have to bite the bullet on, having it properly diagnosed will give you the piece of mind knowing that it's running the way it should be. Depending on what if anything is wrong it may be covered under warranty, hopefully it is for your sake.

You should have gone for an extended warranty, these cars (when out of warranty) are not cheap to fix, general component failure is not common even with crazy mileage. Some things do wear over time and there are countless electronic devices that have serviceable lives. You might want to think about putting some cash aside to cover incidentals that may pop up.

You have a factory 7-year powertrain warranty...Take it to the dealer!
