Help diagnosing vibration

That's my feeling too Phil. If it makes you feel better I can throw your summers on our balancer while they are off so u can see if what the deal is. Hope fully the snows can narrow things down.

i would bring it to Josh, he can personally inspect it, and most likely diagnose the problem with a balancer

Did you miss the part where the wheels were just balanced?

No I didn't. I was offering a second opinion. Just an option

Josh, I was responding to Dani who was saying that the problem could be diagnosed with a wheel balancer. I know nobody is perfect but for now I'm assuming the guys at DT can balance a wheel properly. So if that's the case then it would seem that he problem can't be diagnosed with a wheel balancer since the problem didn't go away after a balance. That's all I was saying. I def appreciate anyone's offer to help.

Nah it's alll good. This is just kind of throwing me for a loop! Lol! I would at least like to get one of our cars working right hahaha! Something like this is almost one of those things where you have to be in the car to know. I have had ALOT of experience with this sort of business. There is never a clean cut method to solve it unfortunatly.

Phil a balancer serves more the one purpose, if you say that you might have hit a large pothole, then throwing a wheel on the balancer can easily detect that, when the wheel is spinning, also it give Josh an easier way to see if the tread is different from one side to another, by looking at the tire when it is spinning all these things can be done much more efficiently when on a balancer

Phil has ALREADY had them re-balanced. So, he is putting on his snows to see if it's related to the wheels!

So apparently Chris is convinced it's the tire wear that is causing it. Thing is I don't get what could be causing the wear. My Koni's are new all around, and everything else in my suspension is in good working order as far as I can tell. The alignment that was done 2 months ago only found the tiniest of errors in the rear toe, which was corrected. The problem has become much worse in the 2 months since the alignment. The tires are about $750 a set.

I think it may have to do with the settings on your shocks. What is most likely happening is the shock is wound to tight and causing the spring to have a hard time doing it's job. Just an idea. The tires are prob chopped?

Apparently they are lightly feathered.

Inside or outside or both?

I don't know.

Hmmm... This is the extent of my diag without observation. Pics would help too brah

prolly inside, Phil whats the your camber on the rear?

Camber doesn't cause feathered tires, toe does.

Adam wins the cookie!!!!!

Correctamundo! Plus the camber is in-spec anyway. I just have a hard time wrapping my head around the idea that such a minor toe problem could cause this much wear, but maybe it can.

The tires are Falken 452's. I found these on just the first page of google search results. Hmm.

so here is the deal i bought a set of these tires brand new two springs ago. I read the reviews and based off that i bought them..loved them to death great tire for the money. well i drive about 80 miles a day round trip mostly highway...By the end of the summer i was having huge feathering issues...(all alignments and tire presures were correct) so i contacted falken and they were awesome and took care of me on the cost of some new tires. i had them mounted back in may its now mid october and i have continued to rotate them every 4k and keep the air pressures correct. i had an alignment done halfway through the summer and now here i am again with horrible feathering issues. Im just curious if anyone else with these tires have run into similar issues???? if so what have you done and does anyone have any suggestions because i am lost here and so is my service dept..(i work in sales at the dealership) any help is greatly greatly apprciated....

The local place here stopped carrying them due to complaints. They pushed them pretty hard with all us locals and once people started running them and having probems they stopped selling them because that were getting tore up in having to replace tires for bad manufacturing.

I wasn't drifting or doing burnouts. I drove the car pretty hard on some autox but i sure as hell didn't put 12k on an autox track. Mine were feathered and wearing out at the first oil change after i got them on there. The tech pointed it out to me. Then i took it to the shop where they procedued to have me bring car in every few months to have it aligned because they said it was my car. Well that didn't fix it and there were quite a few more claims on them wearing out so they will no longer order them.

I've had both the stock RFTs and the Falkens. The falkens with feather and begin to trammel after 8,000 miles or so which will compromise your ride quality (it annoyed the hell out of me). For about the same price, look at the Hankook Ventus V-12 Evos or for a little more, consider the Vredestein Ultrac Sessantas.

Great article about the effects of camber and toe when lowering your car. Explains everything very clearly. I apologize for the site that it's hosted on.

Yeah. Hard cornering has a dramatic effect of feathering. I feather tires on all my cars bc I drive like dani!

This was def not caused by cornering. With the amount of freeway driving I do I guarantee 99.9%+ of my tires' travel time is in a relatively straight line.

Makes sense. Saturdays are the only times I take the highway. Did you swap to winters? Based on what I have been reading it looks like Chris sold you some bad tires... Sorry bro
