Wheels causing Bad HUBS????

[GagToe]

Ok, had my 19's on the car for approx 800 miles. Put on about 4700 miles, went into the shop at 5500 miles. Was experiencing a shaking (like bad allignment) at approx 60 mph. I went to DT to make sure balance was correct. They jacked up the front and shoot the tires, maybe 1/8th - 1/4 inch play in the wheel, took off wheel, play was still there just holding onto the brakes and shaking. Took car to Pontiac dealership. They are warrenteeing it, but with a one time only note. They said the front rims are too big and they were the cause, I'm running a 245 Nitto on 19's I believe its a 245/35/19 Anyone have any experience? I'm a regular, but can't remember anyone else having "bad hubs" Anyone else have problems w/ the dealer because of your wheels? They are doing it for free this time, but if their too "big" I've got to get DT to change them out. I don't think it will be an issue, I have the dealer in writing saying the wheels are too big. The tire calculator showed these to be darn near the exact same size as stock. GRRR I'm frustrated. Someone show me the light at the end of the tunnel.

Entirely possible, yes. That quickly, I wouldnt think so. But I dont think it has anything to do with the diameter of the rim/tire... it has to do with the weight.

I had 18" Mille Miglia Evo5's on my GTP... looked AWESOME, but, I never fully comprehended how deadly excess rotating mass can be on a car's hubs. Those rims n tires were MUCH heavier than stock, and thus, my GTP went through 3 hubs (within ~20,000 miles) due to the added stress from all that extra weight. It took a LOT of miles for that to happen, tho. Amazingly, they covered all of them under warranty.

Part of the reason I bought the Drift R's is that even in 19" size, the rims and tires are almost the same weight as the stock 17's with rims and tires.

Good luck...

I believe the Nogaro's are lighter than stock. I'm not sure, I believe there is a Goat Friendly Service Manager around here, I'm going to chance it was something else. If not, i'll borrow a set of factory 17's next time I take it in even though wide 19's in the back and factory 17's look like :barf:

I'm not sure I understand how the weight of the wheel can cause a problem. The weight of the car is supported by the hub, and that hasn't changed. The wheel is supported by the ground.

As long as the OD of the tire is the same, the hub is still spinning at the same speed, and I can't see why it would cause a problem.

Anyone have an explanation?

Are you sure its the hub and not the strut rod bushings? These things are notorious for trashing the bushings with little to no effort and would definitely allow alot of play. Do a search for "strut bushings" to read more....

First thing is, a bad alignment doesn't constitute a shake in the car. That is completely based upon the wheel/tire combo & the front suspension parts.

Back on topic. The size of the rims shouldn't be an issue. HSV builds performance cars with 19" wheels all day long. They use the same hub/bearing parts as Holden (& used by Pontiac dealers). The question may be the weight of the wheels & if they are hubcentric. The Pontiac dealer may find anything that isn't stock, just so they don't have to warranty. They get paid either way. GM pays them for the warranty or you pay if it isn't warrantied. It's just faster to make you pay.

They said hubs, I'll make sure I get all paperwork. Hmmm

Also see if it actually fixed or not. Obviously. As SCCA said, I don't see it a problem unless they are much heavier then the 19" wheels HSV uses (which are made by ROH )

I'd bet more on the strut rod bushing had leaked out all the fluid (whos idea was it to fill these with fluid anyways?).

or

TSW wheels need hubcentric rings (they usually supply plastic ones.) If you didn't have those on it is possible for you to get a shake.

Although since you said it wobbled without the wheel on, then that leads back to the bushing....or the hub itself, which I really can't see unless it was defective to begin with...


Bottom line, most dealers will try and blame anything that isn't stock so you will pay instead of dealing with getting the refund from GM.

[GagToe]

Yes these are hubcentric rings and yes it has them in em. We'll see when I pick it up.
