Some post in the past said that the Park Avenue an LeSabre were assembled on the same line as a 'Cadillac Model. What one was that? _-- or am I remembering wrong? |
|
| Like several large GM cars, the LeSabre rides on the G-Platform. Because of this, the LeSabre comes off the same plant line as the Buick Park Avenue, Cadillac Deville and Seville, Pontiac Bonneville, and the dying Oldsmobile Aurora. Hope this helps! | |
| There is a vibration, when at idle that disappears when car is put in neutral..Old buick, that I love, has 120,000 miles without any problems to date, except an alternator, two water pumps, and a coil. great car. | |

Have you replaced plugs and wires? I did that at 90K. My great service manager at small town dealer told me to do that on both 93 and 98. Do you feel the vibration the same in reverse and drive? I assume you've looked for hoses or wiring bundles that might be transmitting vibration when engine is twisting again transmission load? Have you checked the PCV valve? It may be not sealing closed at high vacuum at idle if it's dirty and gunked up if the oil ahs not been changed regularly and often? If engine oil's been changed regularly and you don't think the roughness might be something major in engine, you might try some Techron engine cleaner in gasoline (available at most mass parts stores and some others now line Meijers in Midwest). Try one in tank when low with fillup of GOOD brand gasoline (I use Plus or Premium). Then do it again within a half of a tank after the first gas is run through. It's got one of the best cleaners in gasoline (Exxon's brand of cleaner for their gasoline). These are things I found from my 93 LeSabre. Too there was a prom update for roughness at load at lockup on the torque converter under light throttle at 50 or so. I thought it was wires and plugs, but BUICK had a mixture change and a change in the lockup speed for torque converter -- it won't lock in until 50 mph. It used to lock in at 45. That way you don't notice the roughness under load since the converter is not locked up. Good luck. |

Thanks Beach15! That's what I wanted to know. Is there a webpage that explains the differences between the various models by platform? Or explains the differences between the Seville, Deville, Park, and LeSabre that come down the same line? |

Not sure of any specific website that describes the real differences between cars, but I can look. Also, from experience, the only main differences in the G-Platform among the cars it is used are slight variations in wheelbase, and really diverse suspension tuning. The LeSabre, for example, is tuned the softest of all its "relatives", while the Pontiac Bonneville SSEI is tuned the firmest, with the stiffest shocks, springs, and roll bars. In between those two are the other Bonneville models, the Aurora tuned for sport/luxury, and the Deville and Seville, both of which come in a few specific flavors of their own. In addition, most offer variations in stability control systems, but are all very similar as far as overall width. It is also common that the many suspension pieces, for instance, are interchangeable between the various cars. One of the most significant differences are engine choices and differences. Overall, every model is quite closely related. Hope this helps, and I'll try to answer any other question you may have, if possible. |

That's a very good post.... I own a 94 LeSabre and it's fast even without a supercharger but a little wallowy. So what you are saying is that SSEI's suspension components will make it firmer around corners? What particular components would make the most difference? Thanks. |

My dealer was replacing rear struts on LeSabres back in 92 93 to satisfy some customers, using Pontiac SSE or something like that struts. They were the last ones without air leveling in the rear. The dealer put those Pontiac struts on to stop the front-back wallow the soft LeSabres had. In my 98 with air leveling on rear is much stiffer than 93 Custom was. I replaced 93 struts at 35 K because I couldn't stand the soft wallow it had. Replacements fixed the problem. (Monroe struts.)Replacements were same for Pontiac, Olds and Buick cars... It did not have air leveling on rear. Just traded it for 03 Limited. New one is almost too stiff. But only has a few miles on it. What an evolution in ride. |

| I have a 2002 LaSabre and the AM Radio reception is awful, static and noise. I have had the radio replaced once and now the dealer says it is due to the poor reception in the Poughkeepsie area--funny my wife has no problem with her 1989 Olds. Has anyone else been experiencing this problem? I would like to know how to get in touch with Buick to seek their help. | |

You may wish to have the dealer check for breaks in the circuitry of your rear window defroster. It definitely affects radio reception and in my case I got a brand new rear window for my '00 Bonneville under warranty because of that problem. When I turned on the rear window defroster the AM reception was complete static. FM was unaffected. Good luck Ken |
