Chevrolet Impala Steering/Suspension



  • cnwcnw Posts: 105
    I had a clunking/clicking noise whenever--with the car in "Park"-- I put my foot on the brake pedal or took it off. I have bucket seats and the noise came from the console area. Also discovered I could hear the same noise when I depressed the shift-lever button to take it out of "Park". After having parts replaced by dealer, discovered thru some folks on this forum that it is the normal sound for the solenoid that engages/disengages the interlock associated with the transmission and shifter linkage/ brake pedals, etc. All part of the safety stuff to prevent shifting out of Park without having your foot on the brake. You may be exoeriencing the same thing. Clark

    FWIW, my sister (owner of an '06 3LT) just had a tie rod bushing (I believe) and (just before her warranty expired) a rear trailing arm replaced. The trailing arm had broken, at least that's what she was told, and was causing a clunking sound in the rear. Since most of the problems in the Impalas seem to be systemic, you all might want to file that away in the back of your brain in case you start experiencing similar symptoms. I've noticed some clunking in the rear when driving through a parking lot with bad pavement (for example) that I think may be the same problem. I hope to have mine checked out this week while I'm home for Christmas. My selling dealership seems to be better at addressing concerns than the one I use near my home. I'll post any results if I get them.

    Just saw your post regarding the "clunk" noise coming from the rear when going a rough pice of pavement. I have also noticed that but discounted it as just a quirk of the rear suspension. I should have suspected something, because I only hear it in a right turn as the right rear crosses a pice of concrete that drops approximatel 2 inches. Yes, the sound is repeatable and predictable in that same corner. I need to get under the car and do some checking and then pursue it with the dealer. Thanks for the heads-up. Have a Merry Christmas with your family. Clark

    Funny you should mention the right-rear because that's where my sound is coming from.

    Here's another tip for anyone else who suspects a problem: fold down your rear seats and test your car. Any noise from the rear suspension is MUCH louder with the seats down. I discovered this by accident since I have my seats down to aid in hauling around a lot of "stuff" during the holidays. My symptom is more like a crunchy-squeak sound as the springs are flexed. So far, the best way to repeat this is to go over speed bumps slowly. I still have the proper 1 1/2 bounce but that first "1" is very noisy in the right rear.

    Thanks for the input, Clark!

    Merry Christmas to you and yours as well!

  • Hi all,i have a 06 Impala LT with the 3.5 V6. Love the car for the most part but i have this annoying little rattle/clunk from the steering column. You can't hear it as much as feel it in the steering wheel. When turning wheel and accelerating from a stop or just stopped and release the brake and apply it again quickly,you can feel slight movement in the column. It's not like a loose steering wheel and doesn't seem to affect anything,just an annoying little feeling. The car has 21,000 miles on it and i purchased it used at 19,000. I love the car really and this about all i can nit pick at. Thanks all in advance.

    I have an 02 with over 100,000 and it does the same thing. I think it has since early on. I did change the ball joints but that didn't fix it.
  • It's too bad because i really like the car but this little clunk drives me crazy. That and lousy range on the remotes, but what are you gonna do. The remotes should work from more than 20 feet,but 1 annoyance at a time i guess.
  • rysterryster Posts: 565
    The steering column noise is most likely the Intermediate Steering Shaft (ISS). This is a relatively common issue on the Impalas. The dealer may be able to fix it by either replacing the ISS or lubing it. Most people that have it fixed say it comes back eventually. My '06, at 21,500 miles, makes a noise sometimes but I just ignore it.

    The remote range issue can also be addressed by the dealer. I believe that Chevrolet has issued a Technical Service Bulletin for the issue. Last time I was in for routine maintenance, a gentleman in the waiting room was having his Impala fixed due to range issues with his remote keyless entry.
  • Thanks for the reply. I will check with my local dealer on both issues. At least i can go in and listen intelligently.
  • quietproquietpro Posts: 702
    See my post (#84) regarding the ISS. I had mine replaced under warranty and that hasn't been the usual. Mine started clunking at around 25,000 miles and got progressively worse.
    Both of your issues, ISS and remote range, should be fixed under warranty. There is a TSB for the remote range that involves replacing the receiver and issuing new FOBs so you DEFINITELY want to get that done before your warranty expires.

    Good luck and keep us posted on your experience!

    My '06 SS has been getting progressively noiser in the rear suspension. Originally, I thought it was only the right side but now it seems to be both sides. It seems to be worse when the car is cold. I don't hear it much in the mornings since my car stays in the garage but when I leave from work, after the car has fully chilled during the day, it is much worse. Anyone else having similar issues?
  • I read somewhere that there is an antenna mounted in the roof pillar on the drivers side (left side of the windsheild) that is connected with a plastic push connector. The article said that if you remove the plastic interior molding from the pillar you will see the antenna. Remove the plastic push connector and replace it with a metal screw. The antenna is mounted to the body in order to make the whole body an antenna. My 06 Impala SS has the same issue with having to be close to the car to remote start and open the doors.I am going to try it this weekend. I talked to the dealer about the range issue and he check the vin number and said my car was not in the incall group. I have read other 06 Impala owners postings about that same issue and they think, like me that their car should be in the recall group.
  • I bought my 06 Impala with 53,000 miles on it about a week ago. I have loved it, up until yesterday, when while just driving along one of the mall roads, it started to make a strange squealy whiny sound that came from the steering column area. When that sound started, it was nearly impossible to turn the car. It ran fine and shifted, etc without a problem, but when I had to turn on a road that was just about impossible. I barely made it back into my driveway -had to use two hands to get it to turn enough to get in the driveway. Needless to say, I'm a bit "peeved" about this. I have to get a rental car today to be able to make it to work Monday on time. I'll have to call the dealer promptly at 730am Monday morning to have them come TOW it back to the shop where they will have to repair it.

    This really ticks me off, because my car I traded in for this one, a 1997 chevy lumina with 145,000 miles on it NEVER failed me. It had misc. little issues, but I was always able to get to work and back and drive around without any problems.

    I have an 06 Impala SS with aprox.18500 miles on it.Im in NY state so it can get a little chilly here in the winter.My wife went to back the car out of the driveway Friday morning and had no steering.She called the dealer and he had it towed in.It seems that there is a problem with the power steering hoses on the Impalas.The SS and regular models are affected.GM is aware of the problem asd I recieved a bulletin from the dealership explaining the problem,and the fix.
    It is also known on the Monte Carlos also.

    i also have a 2002 impala. the traction control system light comes on for no reason daily for a week or so and then i won't have a problem with it for a couple of months. my gas gauge is also wacked out. i never know how much gas i have because the gauge will say full one minute and almost empty the next, so i just get gas every couple of days so i know i won't run out. last but not least i have a grinding in front end, thought it was brakes but it only happens when it is cold. once i drive for a couple of minutes it is fine.
  • axinutaxinut Posts: 11
    A simple way to fix the gas gauge issue may be to run a couple of tanks of gas with "Techron" in it, two of the major oil companies has Techron in their gas, I think they are Chevron and Texaco. Sometimes this will solve the problem.

    When my 2000 Impala was fairly new I had a problem with a clogged injector, which was fairly expensive to repair as I recall. Someone suggested running a fuel-injector cleaner (like Techron, which was the brand I bought most often) through the system ever time I changed oil, which I did. I never had any more fuel system problems...never had fuel gauge problems either, but can't say that was necessarily due to using the fuel system cleaners.
  • axinutaxinut Posts: 11
    This is a very common issue with Corvettes of this vintage, a tank of gas with Techron in it will usually cure the situation.

    Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver. This condition may also be felt through the steering wheel when the vehicle is stationary and the wheel is rotated from steering stop to steering stop. Some vehicles may only exhibit the noise once for every 360° of wheel rotation. On all other vehicles, this clunk noise will be noticed during low speed acceleration or deceleration, typically in light turns of the steering wheel or when applying/releasing the brakes.

    This condition may be caused by a "slip stick" condition resulting in the clunk noise or feel through the steering wheel.
    Diagnostic Tip

    Important: This condition is commonly misdiagnosed as originating in the steering gear and has resulted in the replacement of numerous steering gears without correcting the concern.
    Attempt to duplicate the customer's concern and isolate the I-shaft by following the procedure below:
    Locate a large area (parking lot) where the vehicle can be turned in a tight circle. Turn the steering wheel to the right and/or left all the way to the steering lock, then off the steering lock a 1/4 turn. Drive the vehicle approximately 5 km/h (3 mph) in a circle, preferably over rough pavement or seams on the road surface. If a clunk is felt in the steering wheel, the MOST likely cause is the I-shaft -- not the steering gear. Continue with the correction.
    Drive the vehicle straight ahead at idle speed while applying and releasing the brake pedal. Listen/feel the steering wheel for the clunk-/noise condition.

    Replace the intermediate shaft
    DO NOT lube the intermediate shaft.
    Replace the existing intermediate shaft using the service procedure found in Service Information.

  • I also having the same issue with my 2002. Did you ever get answers?
  • I have an 07 Impala that started doing the same thing this fall at about 45k miles (also cooler weather). I suspect the valves in the MacPherson struts are a poor design and are getting "slappy" with age. Too bad as other than that this is a perfect car.
  • I have a 2001 Impala, and it sounds like your power steering is going out. Mine went out around 70,000 miles so that might be what it is.
  • Last night, I got a call from my daughter Katie. She had car problems, but she was rather vague about what problems she was having. I got to the location she'd asked me to come to and found her sitting in the back of a police car. The '06 Impala SS she'd been driving was nowhere to be found, so I looked around for a few minutes.

    Finally, I spotted it. The car was about 30' down in a ravine. Kate was turning left when the steering locked up. Yeah, right, I thought. I would've tried that when I was sixteen, too. She hit a curb, two trees, some brush, and a bunch of big rocks down the hill. Car's likely totaled - both sides beat in, left front wheel off to the side, hanging on by the brake line. She walked away without a scratch. Shaking like a leaf, but unscratched.

    I've been looking around the net, and it looks like GM has been aware for years of steering problems with these cars and not done anything. We can replace the car. It will cost a bunch of dollars, but anything built can be fixed or replaced.

    I think THEY need to replace the car, since it was a known defect. I think our insurance company doesn't need to pay out the value of an '06 SS, and Katie doesn't need to have the claim on her record.

    Anyone else had any similar problems, or does anyone have an idea of how to get GM to step up and do the right thing?

    I've turned on Email alerts for this topic. I'll look forward to hearing from some of you, hopefully soon. Have a great day today and a better day tomorrow. Stay safe, and may God bless. I wish you His peace.

    I am sorry to hear of Katie's mishap but glad she was unscathed, perhaps a testament to the car's safety quotient.

    I have an '06 SS with approximately 18,000 miles on it and have never experienced any steering issues. I wasn't aware the 2006 Impala had any known steering defects apart from the intermediate steering shaft issue, which thankfully I personally have not encountered.

    What "known defect" specifically are you referring to and is it known to result in accidents?

  • After Katie's wreck, I BINGed the subject of Impala steering problems. I hit all the safety sites and all the Impala sites i could find, and came up with quite a few hits.

    The Intermediate Steering Shaft issues are merely inconvenient for most people. My daughters drove this car and if the steering was making noises, I was unaware. the original GM fix for the problem was to lube the shaft every 10,000 miles. Now the GM fix is to replace the shaft. It seems a natural progression from a shaft binding up occasionally to a point that it locks up. I don't know if that's valid, but it seems to me to follow.

    I'm having the parts pulled and I may sned them out for testing.

    Thanks for your good wishes for our Katie.
  • Just got the shaft replaced today 3rd time on 2001 Monte Carlo GM paid half $ 67.65 This problem is not going away :(
  • My 2005 Impala had it's steering shaft replaced right at 31,000 miles and now is showing signs of the same noises as before, I currently have 64,000 miles on my Impala. My sister-n-law also purchased a new 2005 at the same time as me and her steering shaft needed replaced at about 30,000 miles. I'm sure it's only a matter of time before hers needs replaced again also. This is a definate issue that needs to be delt with by GM.
  • You may want to consider having a qualified mechanic simply remove your existing ISS (intermediate steering shaft) and lubricate it with the proper grease since the shaft is not bad, but has merely run out of grease.
