I have an intermittent vibration that is becoming more frequent. It comes on anywhere from 30 to 50, and sometimes goes away after 2 minutes, sometimes stays for 10 minutes. It is not engine speed dependant. I checked the lug nuts to make sure none had worked loose, and that did not help. It feels like it's in the front end. I had all the tie rod ends and ball joints replaced two years ago when I got the car. I'm wondering if it's one of the wheel bearings or something but I'm at a loss. Any ideas are welcome.
Easy to check wheel bearings....that is where I would gravitate to if you're feeling it up front. Check your driveshaft u-joints, too.
Its impossible to figure out a vibration on an internet forum . Obvious first thing to check is wheel balance . And just because you replaced the tie rod ends and ball joints 2 years ago means nothing . Everything needs to be checked .
Well I lucked out and I have a guy who has grown up on Buicks coming over tomorrow. And he's an ASE Master Mechanic, so if he can't fix it, I'm truly screwed.

Another thing to look out for is the double cardon joint. I'm not positive, but I think LeSabres had them like the 225. Its located on the rear of the driveshaft where it bolts to the diff. Its a ball socket with some springs, washers, etc. Good thing to double check no matter what. Its not fun when that fails.
