Just inherited a 2003 LeSabre Custom with 10,000 miles. It belonged to an elderly family member that drove the car a couple times a week, but less than 20 miles/trip (ie, around a small town). It hasn't really been driven since March.

At 65 mph, I get a vibration in the car. I feel it in the seat. If I have a drink in the cup holder, it will shake. The vibration goes away above 75 mph and below 65 mph. I don't feel the vibration in the steering wheel nor do I hear any unusual sounds.

The tires (original) were showing signs of dryrot so I replaced all 4 tires from a shop I've used many times. No change.

The brakes weren't "smooth" so I replaced the front rotors and pads - now they are smooth.

But, I still have the vibration with no change.

Any ideas?

Thanks in advance.

 

I have a 99 LeSabre and I have the same problem. I have spent about $2k trying to fix it and it still has the vibration. I have replace axles, hubs, rotors, bushings, struts, tires, etc. I have had all four tires and rims road force balanced. I have taken it to a transmission place and had them look at it. I have a friend that is a GM certified mechanic that works at the local Buick dealership that has tried everything that him or any of his coworkers can think of and nothing has helped. I love the car but the vibration is driving me nuts. I am fixing to get rid of it and get me a Park Avenue and be done with the LeSabre's. I think this is an fairly common problem with the LeSabre's.

 

Yeah, I have had the transmission, motor mounts, CV joints, axles, etc all inspected and they all check good. No one can figure this out. Hard to believe a car with 10k miles would have this problem. I've been a Toyota owner most of my life. I have a 2003 Tundra that has 140k miles that I've never had to do anything to except basic maintenance. I surely wouldn't buy a Buick now.

 

Try Checking The Rear Brake Rotors & Axle Hub Bearing , I Had The Same Problem With My 2001 LeSabre Limited.

 

How many motor mounts does 2003 Buick lesabre have?
My engine want to jump when I shift from D to R or from R to D. I was told that engine mount should be replace online, but in the first place, how many motor mounts does 2003 buick lesabre have? Thanks in advance!

 

The vibration goes away above 75 mph and below 65 mph. I don't feel the vibration in the steering wheel nor do I hear any unusual sounds.。。。
