TTQ B4U Posted January 21, 2013 Report Share Posted January 21, 2013 2007 Entourage Minivan with 68k on it. Thought initially it was wheel balance but have had it balanced twice and still no go. Don't drive it often but today I noticed this: Steering wheel will seem to "wobble" at 45mph on smooth roads around town. On the highway cruising at 75mph there are stretches where it's smooth as can be then it will begin to vibrate like it's way out of balance, and again, cruise smoothly at times. What are your thoughts on cause? Quote Link to comment Share on other sites More sharing options...
POS VETT Posted January 21, 2013 Report Share Posted January 21, 2013 Try swapping front wheels side to side. Quote Link to comment Share on other sites More sharing options...
stangsn95gt Posted January 21, 2013 Report Share Posted January 21, 2013 maybe a caliper is sticking Quote Link to comment Share on other sites More sharing options...
Furloaf Posted January 21, 2013 Report Share Posted January 21, 2013 Warped front rotors could cause it as well. Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted January 21, 2013 Report Share Posted January 21, 2013 You could try greasing the ball joints and tie rod ends and see if it helps. Maybe check the tires too for inconsistent wear. Quote Link to comment Share on other sites More sharing options...
Cordell Posted January 21, 2013 Report Share Posted January 21, 2013 Sounds like wheels or tires to me, just because they balance doesn't mean they have good runout specs or roadforce. (although I will admit that a vibration caused only at certain speeds is typically a balance issue) They should be rotated front to the back and re-driven to see if the shimmy moves from the steering wheel. After the wheels and tires are properly ruled out as the issue should you consider something else as the cause. I would also consider trying different gears and loads on the drivetrain to see if the vibration is effected at those speeds, this would help narrow it down.

PRD2BDF Posted January 21, 2013 Report Share Posted January 21, 2013 Join the club with this damn Maxima. Does it with both sets of tires. Quote Link to comment Share on other sites More sharing options...

What are your thoughts on cause? wheel balance or road forced? text me tomorrow if youre interested in getting them on the road force Quote Link to comment Share on other sites More sharing options...
SinisterSS Posted January 21, 2013 Report Share Posted January 21, 2013 have the balanced checked on a road force balancer, here's a service bulletin for your car. Hyundai Technical Service Bulletin 06-50-013 TIRE AND WHEEL VIBRATION AND RADIAL FORCE VARIATION. THIS BULLETIN SUPERSEDES TSB# 01-50-008 TO INCLUDE ADDITIONAL INFORMATION. NOTE: Each wheel and tire assembly is precision balanced and force match mounted before the vehicle leaves the assembly line. Dealers should not alter the dynamic balance of any wheel unless a customer describes experiencing a tire/wheel vibration condition. DESCRIPTION: A customer may describe a steering wheel vibration or "shimmy" condition in the vehicle. Sources of vibration/shimmy may be from the following conditions: 1. Wheel and tire assembly out of balance 2. Wheel out of round 3. Tire assembly stiffness variation (Radial Force Variation or RFV) RFV (Radial Force Variation) may be defined as the amount of change in stiffness of the sidewall and footprint when a load is placed against a tire. Wheel and tire assembly imbalance should be addressed first because it is the most common cause of vibration. A well maintained off-vehicle, two-plane dynamic wheel balancer can accurately correct this condition. If a vibration or shimmy is still present after an imbalance condition is corrected, any out-of-round condition of the wheel and force variation of the tire must be addressed. NOTE: All of the above conditions may be addressed at the same time if equipment is available such as the Hunter GSP 9700, which is a two-plane wheel balancer. Page 2 of 4 For proper diagnosis, it is important that the wheel and tire assembly first be confirmed and corrected for wheel run-out and tire assembly stiffness variations that may cause vibrations before replacing any component(s) on the vehicle. COMMENT: To correct vehicle vibrations caused by wheel out-of-round and tire stiffness variations, access to a Hunter GSP 9700 or equivalent wheel balancing machine is necessary. If you do not have access to such equipment, it may be located through the Hunter website (http://www.gsp9700.com). For information about the purchase of a Hunter GSP 9700 and Hyundai’s special pricing, please visit website (http://spx.com). Page 3 of 4 Technical Service Bulletin Group Number Follow the machine manufacturer's procedure to measure and correct wheel and tire assembly RFV related vehicle vibrations. The following assembly RFV may be used as guide: • P-Metric passenger vehicle wheel and tire assemblies = 18 ~20 lbs or less • P-Metric SUV and Van wheel and tire assemblies = 24 ~27 lbs or less NOTE: This information is a guideline, and the RFV range accounts for machine variability. CHASSIS 06-50-013 Page 4 of 4 If force match mounting the wheel and tire assembly to the above guideline cannot be achieved, it may be necessary to replace a wheel or tire or both to correct the vibration condition (see note below before replacing any part). Since tires can sometimes become temporarily flat-spotted, the RFV should be measured immediately after the vehicle is driven at least 10 miles. (If the RFV cannot be measured immediately after the vehicle has been driven at least 10 miles, elevate the vehicle on a hoist to stop the tires from flat-spotting). Tire pressure must also be adjusted to the recommended pressure shown on the driver's door or B-Pillar. NOTE: If the vehicle vibration condition cannot be improved to an acceptable level using the above procedure or a tire or wheel is required to be replaced to correct this condition, contact the Hyundai Technical Assistance line at (800) 325-6604. REQUEST TO CALLING TECHNICIAN: The dealer technician must provide the following information to the Technical Assistance Line: 1. Condition or customer description 2. VIN 3. Mileage 4. Tire size 5. Tire manufacturer 6. Tire condition 7. Wheel - alloy or steel 8. Imbalance values (inside and outside) 9. 1st and 2nd order RFV values in lbs 10. Wheel run-out values (radial and axial) 11. Location of the wheel on vehicle (RF, LF, RR, LR) NOTE: Printed copy of any of the above information will be appreciated. Quote Link to comment Share on other sites More sharing options...

Most places that "balance them" will throw whatever weights it calls for. Just because it zero's out does not mean its balanced. Road force them and rotate to back. Also check tread on front tires and make sure it is wearing even. Quote Link to comment Share on other sites More sharing options...
TTQ B4U Posted January 21, 2013 Author Report Share Posted January 21, 2013 awesome. thanks guys. will post back with findings and results once done. Quote Link to comment Share on other sites More sharing options...

TTQ B4U Posted March 18, 2013 Author Report Share Posted March 18, 2013 Mother has the exact same van and had the same problem right around your mileage as well... Update.....tie rod need replaced. doing both and getting an alignment. Taking the race van to IPS for the above and a couple of other items. Nearly 1/2 the price of what the dealer cost is.

IVRINGS Posted March 19, 2013 Report Share Posted March 19, 2013 They are good guys that I still use since they are so close to my house. If I didn't have techs at work that are doing side work for $25 an hour I would be there more. Quote Link to comment Share on other sites More sharing options...
