Buick LeSabre Steering/Suspension

I have a 2005 Buick Lesabre with less than 10,000 miles. The car has a consistent vibration at highway speeds even though we have tried a new set of tires and a complete rotation and balancing of the tires. The dealer indicates there is no problem with the car; however, the vibration persist. Is anyone else having this problem?

    Which size wheels and tires do you have? The 60 series tires tend to be stiffer. The problem is a known problem due to lack of tire quality and the lightness of the suspension parts and the rigidity of the car chassis-someone told me it's based on the original Aurora and Riveria.

    The tires needed to be Road Force balanced using a Hunter 9700 balancer. If your dealer doesn't have one, find a dealer who does. This adjusts for the uneveness in the tire's rolling height when under pressure. In other words, many tires don't roll round; even if they're balanced they crush differently on one part than another under the car's weight. So they essentially roll as if they are not round.

    Park Avenue and some LeSAbres and Sevilles went to Michelin tires (Symmetry) to get away from tire imperfection. The company swapped tires on Park AVenues to put on Michelins to fix the problem.

    Also, the wheel alignment affected my 03 with 16 wheels and Michelin symmetrys that it came with. I had a good service manager who used the vibration analyzer to be sure it was wheel and tire speed related. I told him that after he had really carefully balanced them, it seemed to oscillate on uphill pulls but not ont he downhill pulls o smooth interstate in Tennessee. He felt the alignment wear on tires and took it in. The rear were out of toe and the front also. He set them to what he considered the middle even though they were within tolerance. GM paid for alignment touchup up to 12000 miles. So get back with alignment complaint andget them to print it out. Also do Force Balancing.

    Fixed it. Ain't perfect, but no car is. They stayed balanced until 35K and I paid to have them rebalance @ $7.50 each.

    What tires were on the car and what ones did you replace with?

    Wjohns02,

    Do you have a cabin air filter installed? Did it come with the car? I just purchased a 2005 Limited Prestige with the Celebration package, but no cabin air filter.

    The filter was omitted after 02 with little fanfare. You can buy the plastic skeleton holder which snaps into the heater box and it comes with a filter. You might try aftermarket but the skeleton is probably a dealer only item. The filters are about $18? at PepBOys-Purolator.

  • Thanks Imadazol97, I don't know why Buick would drop the cabin air filter. Really keeps the interior cleaner. I'm asking my dealer for a holder.

    I have a 2004 Buick LeSabre with the same problem. I have been to the dealer again and again. Sometimes they tell us we are nuts, there is no problem; sometimes an honest technician says, yeah, this car has that problem and we don't know how to fix it. They have even tried new Michelin tires. I have initiated a Lemon Law complaint with our state attorney general's office. BBB Autoline (Better Business Bureau) has a website that can help you get started. I would encourage you to stick it out; I test drove a used Buick before purchasing mine and it's vibration was even worse - probably a testament of what is to come. Unfortunately I had no idea this was a consistent problem with the LeSabre, or I never would have bought mine. Good luck. :sick:

    Which Michelin tires were put on?

    Was the car aligned correctly?

    Has the car been driven with the vibration analyzer attached to various parts to diagnose the vibration type?

    Were the wheels force-balanced on Hunter 9700 by someone who knows what they're doing? Preferably a GM dealer who knows what's needed for trouble-shooting the vibrations in the stiffer frames with lighter parts in today's modern cars?

    Mys 2003 Les with cheap Goodyears has no problem, there are tsb's out there about the issue relating to this being more prevalent with the lite weight suspension components, as mentioned a road force balance is important and there is even a suggestion of replacing front hubs and bearings.Even a slight runout is felt in the car.

    FWIW, Michelin Harmonys stopped the vibration in mine. I love these tires. Quiet, good traction, great ride. Had them on 1.5 years and 21K miles.
  • imidazol97imidazol97 Crossroads of America: I70 & I75Posts: 17,731
    I'm glad you mentioned them on you 05. I have an 03 with Symmetrys on it and I want to put the Harmonys on as I wear them out two-by-two. I have Harmonys on my 98 leSabre.

  • I am driving Lesabre 2001. It made 36K with no problems and no other maintenance than oil and air filter change. While oil change service the shop recommended fuel injection cleaning, and transmission power flush. User manual does not mention this at all. Should I go ahead with this recommendation?.

    Only if you don't mind donating to the shop owner's summer vacation home fund or for the college fees for his kids.

    The injectors are kept clean by the detergents in quality gasolines, which is most brands. Use a few tankfuls of only a top tier http://www.toptiergas.com/retailers.htmllink title

    The transmission probably benefits from a drain and filter change between 36 and 50K. But the shop manual doesn't recommend that early a change; I think it's 100K unless you use it in hillclimbing, taxicab service, etc.

    The flush concept is another money maker in my opinion. They don't take the pan off and drain the fluid in the pan and change the filter. That's the preferable method even though it drains about 60% of the fluid that way. I doubt that the flush method which means easily connecting a nice machine that pushes fluid through is better at getting all the old fluid out.

    I drain and change my own fluid and do it about 36 K just for preventative maintenance. Find a local, reputable established local shop from friends or family. Pay them to drop the pan, change the filter, and refill with Dextron III. Cost of filter at PepBoys $18; fluid, $15+; the old gasket is reused because it's rubber and contains metal to conduct heat to the bottom of the pan to help cool the transmission.

    Hello. I have a 2001 LeSabre with roughly 37000 miles on it. I bought it used 6 months ago and hadn't had any problems until fairly recently. In late January I started noticing a front end vibration in the car. It's intermittent and doesn't appear to be specific to any particular speed (it happens at most speeds) but sometimes I'll go for days without it happening at all.

    Now I am noticing that the steering wheel is tighter than normal. I can still make turns with no problems but something doesn't feel right (in addition to the vibration).

    I've had the tires balanced and aligned so now I'm thinking it might have something to do with the steering/suspension but I'm not sure as I don't know much about cars.

    Any help would be appreciated.

    Hello! I have a 93 Buick Lesabre that has been leaking power steering fluid for some time now. About every other day i need to put more power steering fluid in. My husband looked under the car and seen that it was leaking from a thing called a cooler tubing. Does anyone know anything about that, he said the box thing that is there is real rusty, hes hoping he could by pass the tubing some how, if anyone understands what i'm talking about and can help please let me know thank you audra
  • Hello,

    My LeSabre has been in the dealer's shop several times and they can't seem to find what the issue is. The Stability Sensor light comes on and off periodically and the front end while making turns, in either direction, makes a stretching sound. Almost like a rubber band being stretched too far.

    I had another mechanic look at the front ens suspension and he said it was NOT the struts and the front end looks good. I am wondering since it is when turning, if it's something with the steering or could it be the idle arms, u joints, stability bar or something else they may be related to the steering housing.

    Help!!!I can't continue to let my child drive this car like this worrying that they will break down somewhere.

    Thansk,

    Sandy

    I recently changed my rear struts on my 1995 Buick Lesabre. I replaced my springs also. On one side of my car the bottom of the tire is tilted out and the top is tilted in. How do I go about fixing this. I have to do most of everything myself because I am financially strapped at this time.

    Thank you,

    It needs an alignment. When you replace struts an alignment needs to be done or you'll wear the tires, which is expensive.

  • Where can these be bought at a lower price than $128 a piece from GM.Or do these press in and out??

    Can't find the parts on rockauto.com
    gmpartsdirect.com has

    link title
    Identify the part or parts and look in their listing under rear suspension.
    I'd sure do some asking for parts at local advanceauto and autozone and others. The replacement brands should work just as well.

    Good luck. What happened to yours?

  • I replaced the front inner and outer tie rods.I was looking at the back ones.I found out today that the rear inner tie rods are replaced,not pressed in.Just as I suspected.I took off the mini boot that is on it and greased them up and put the boot back on and then replaced the outer tie rods on them.The inners are good for
    another 10-20000 milkes.I was lamenting to Medley's Alignment(after I did the front end inners and outers and rear outers I had to get it aligned)he said he could get
    them for me for $80 apiece.Heck of a lot better than $128.By the way it drives like
    a New Car.

    Have inner and out tie rods checked.They have been known to fail at that mileage.
