I have the dreaded 60-80mph vibration in my sts. I was told by the dealership that i need the roadforce balance. Which would cost me around $150!!! When i looked up info on this, i was pretty sure they are supposed to pay for that balancing, or put michelen tires on it. I currently have the ggod years right now. I know of TSB 00-03-10-006 which states the roadforce balance. BUt am i supposed to pay? Any info on this would be great,
Frank

I would think that it would be a "customer pay" issue after the original post delivery service check. In other words, once you were happy with the cars ride quality, that says that the OEM did a proper job. Thereafter, all wheel balancing would be a "maintenance" type item unless you can show that the vibration was being caused by a mechanical issue.

My partner had the local dealer do the road force balance on his Chevy 1500 4X4 at his expense, and they advised that the tires were bad. New truck with about 18,000 miles. The original tires were Firestones and he went an put new Michelins on and has been happy ever since. You might try to rotate and balance first at minimal expense, and see if there is any improvement. If not, then you might look into road force balance or new tires. Good Luck either way.

the stock Eagle GAs are the friggin worst. Michelins...now that's what I'm saying. No more road vibration for me.

the change in tires cured the problem entirely, chuck?

I have a 2001 DTS. It has the same mount system as the 2001 Seville. I found mine had a front lower engine mount begining to tear. New mount and moved one front wheel to the rear has fixed the problem.

That plus a proper tire balance.

I replaced my car with Michelin Symmetry tires by replacing the rear tires first (defective Eagle GAs needed to be replaced in the rear after one went flat) and I noticed a tremendous improvement in handling, noise, and stability. Then a half year later I put Symmetrys on the front and it was serendipidous (sp?).

Nice......anyone else out there change tires? i definitely would have tried that on my SLS, seems obvious now

Brett,
I've down that path :banghead: , I had to get rid of the goodyear eagles ( junk). I now have a set of Michelin Pilots that have be force load balanced on my 99 STS. 65 to 73 mile per hour vibration gone .
Take care,

I took those sorry ass Goodyears off my '96 SLS and installed BF Goodrich Touring T/A HR4's. Stock size,225/60. All the difference in the world! Smooth, quiet and they handle well wet or dry! I wanted to go wider but stay the same hieght, all I could find were BFG T/A radials in 265/50/16, I was afraid they would be too wide and cause other complications.

Had Badyears with the vibration. Swapped to Michelins Pilot Sport A/S. Still had vibration. Took TSB to dealer. They did not have a Hunter GSP 9700 balancer. I went out and found one and the dealer paid for the balance. Seems to have solved the vibration. This dealer has been pretty good to me in the past. I have also been very polite with them.Treat someone else how you would like to be treated. Works every time.

I have Falken Ziex ZE-502 tires. They were on the car when I bought it. I love these tires. No vibrations at all.

I haven't seen any mention of these tires so I thought i would throw my 2cents in.

The '98 STS I just got with 33K on it had BadYear Eagles. Bad Vibration in the front but I could tell the tires had never been rotated. Took them to my tire guy/mechanic. He started to balance the Goodyears and then found the tread was separating on the two fronts. I ended up putting on a set of Cooper SLE Touring tires. I have these on my '94 STS and they are great tires in most all conditions. H rated. The '98 is now smooth at all speeds. No special balance required. Hopefully they will stay that way. I have read a lot about the 'balancing' issue and thought I may have probs, but the Coopers seem great on this car!

I did have Michelin Pilots on my '94 (tore the Eagles of it too- they sucked). The wore like iron, but were very harsh riding. The Coops are a better ride and way better in rain and such.
