Re: 2003 Park Avenue Ultra with bad vibration at highway speeds [brucgraham by schwenk1

Goodyear tires used to bug me on my 99 and 01 Park Avenues. On the 01 I changed to Michelin Symmentry and got a smooth vibration free ride. On my 03 Park Avenue I had them install Michelin Symmentry tires before I took delivery. Nice smooth riding with them so far (66,000 miles).
 
Stay away from Goodyear tires.

The tires were roadforce balanced three times at a shop, Samaritan Tire MN, with a reputation of doing very good work. Today I took the car to Buick/Pontiac garage where they were kind enough to look at it but wanted to begin with the tires. I assured them the tires were properly roadforce balanced last week for the third time. I took it to the Chev garage and the first thing they did is take the wheel/tire off and checked the balance. Excessive road force on RR, was 39 lbs. It was corrected to 24 lbs. I again had all tires re balanced, this is getting expensive! Enough for the good work at samaritan. It ops tested a little better but still has vibration. Rear bearings appeared to be good. They did find a front wheel beaning with some wobble. They did not have a Delco bearning in stock and the mechanic recommended I use original part rather than a aftermarket part. I am not sure this is the pronblem but I will need to replace it prior to aligment. Tires did not have any noticable problems. Thanks for all the help.

I most likely will have to deal with the Goodyears until they wear out! Maybe a aliment and bearning replacement will bring back a smooth ride. Thanks for the info on the Michelins.

The maximum allowable for diagnosis on H-bodies for GM's troubleshooting is something like 18 pounds. My Michelins on the car when new were 12, 11, 9, 7. They did rotate one tire on the rim to reduce the effective roadforce. Those were Symmetry tires. This was in 2003.
 
My new Harmony tires on the same leSabre now were all under 10 when roadforce balanced at the local good mechnical and tire store at about 10000 miles. I wasn't satisfied with the regular balancing at the local store and went to the nearby store which has the roadforce balancer. I have a sensitive butt for balancing and vibration. I actually was happy with the standard balancing on the Harmonys when new; but when I had them rotated and rebalanced after 7-8000, they weren't nearly as good. Turns out the tech had three of the tires off by .50 ounce based on measurement at the roadforce balance store after 4-5000 miles of driving. Tires don't change that much.
 
The hint about Michelins comes from GM having trouble with the H and C bodies that were built on the technology of the Riviera and Aurora with the stiff chassis and light moving parts-like A-arms made of alloy. They started replacing tires on troubled cars with Michelins under factory warranty to trouble shoot them. The Cadillac Sevilles and leSabres with 16-inch Celebration wheels shipped with Michelins; some Park Avenues and leSabres had high level Firestones on the 16-inch rims. Standard leSabres used General tires that were very soft and easy rolling.
 
When the service manager was having the alignment checked on my car at 11,000 miles, he pointed to the other brand of tires they were putting on a Grand Am in the dealership. The roadforce amounts on the balancer were in the 20s on the brand of tire.
 
The problem is you are trying to balance doughnuts. Does the store who sold you the Goodyears sell Michelins. As them for a trade allowance.

Rust by dafraq
Aug 08, 2008 (2:38 pm)

Hi all,
 
I was doing some inspecting around the bottom of my doors because the rubber door seal (flashing?) has rusted loose on the driver's side. It appears that the metal screws used to hold the rubber in place have begun to rust out and in turn have rusted the bottoms of the doors. It is not as bad on the passenger side but it is beginning.
 
Has anyone else experienced this?
 
Does anyone know where I can get new rubber flashing?
 
What is a tried and true way to stop rust in its tracks?
 
The car is nearly mint and I want to keep it that way. Love the PA!
 
Thank you,
 
David

There was a paint for rust that turns it black. It contains sulfur IIRC and chemically combines with rust and free iron to give a black coating which can then be painted.
 
You are at the point where you should take off the door panel and take off the water barrier that's caulked to to the door and directs water down to drain holes to go back outside the rubber seal through holes in the bottom of the door. I would expect there's been blocked holes on the bottom of the door that drain the water out.
 
I'd paint the inside of the bottom of the door with the above mentioned chemical paint and then make sure the drain holes are open and the plastic and caulk feeds the water that gets to the inside of the door (down the window) goes to the holes. The caulk should be new, black sticky stuff on the lower part.
 
I'd check into the push pin type replacements for the metal screws--Lowes has them in their bolt and screw drawers.
 
Check this link for a good door picture set.

Thank you for the info. The picture set is great. If you look on the top picture on page 3, my problem is with the black rubber stripping on the bottom of the doors that runs the length of the car on both sides on the outside. Do you happen to know what that piece is called? Do you think I can get away with just replacing that piece and use the push pin screws after fixing the rust or should I venture into the door panels?
 
Thanks again,
 
David

My Front Left/ Right Door handles broke. I've searched everywhere online as to where I can get replacement parts. But non to avail. Anyone have any recomendations? Iv'e seen Buick Century's door handle and they look similar. By any chance would they fit?

I have checked ebay,Theres none. The handles are for the outside. Which I think is the most common problem I've read around this forum.
