So I had to take my z out of the garage yesterday for a drive to the bank. And I was having a serious wobble going on that was pretty bad. But after 10 minutes of driving the wobble went away. When I reached the bank i parked the car for 15 minutes. I came back to the car and began to drive home where the wobble came back!! I do have rear wheel spacers . The car was aligned. I am in a snowy cold environment I don't know if that would mean anything. But thank you for the help.

 

check the lug nuts, check if the wheels still have the weights from balancing.

 

Is wobble in the steering or is the entire car shaking?

In addition to above, start with checking tire pressure.

 

How long was it stored? Lots of variables but if your mentioning spacers I would say thats a good place to start... Along with checking your lug nuts, tire pressure, ball joints, tie rod ends, etc...

 

Dont be like this guy... Not good for anyone.

 

Lost a lug didnt he?

 

If it happens again, check for snow in your wheels. Yesterday the wife was complaining of wheels shaking/wobble feeling. I had her pull over and cleaned the snow that was all packed on one side of the wheel. No more shaking. Just a thought since you said you live in a snowy environment.

Everyone told you to ditch those wheels.

 

I'm guessing its the spacers but if I were you I would ditch the whole setup.

 

What kind of spacers did you install, bolt on or slip on with longer studs.

 

Ditch the spacers

 

Lower ball joint broke, I was just nice and removed the wheel so it wouldn't go flopping into the fenders... When lug nuts are loose and the wheel falls off usually you can put it back on and its easy to load...

Unless its like this sweet ford

 

If it was stored for a while I'm with the other guys! Check torque on ALL the lugs. Inspect the spacers (which means pull the wheels off and not just look through the spokes) and check your air pressure in ALL tires. Rotate them if you're able to and try that. Kinda sounds like a bent rim or broken belt in the tire at worst if the wobble is at one certain speed.

 

Wouldnt happen with the bbs wheels... still waiting on that

 

Depending on how long the car was stored and the outside temp - I would bet that the tires are flat spotted from sitting in the garage. once they warmed up a little it went away, but since it was a short trip once you parked the car they deformed again.

Just make sure you have the correct tire pressure, and if possible put something down between the tires and the concrete. Concrete gets so cold it leaches moisture right out of the rubber and helps to flat spot the tires.
Once the temps warm up and you start driving the car for longer distance and more regularly, it will go away.

 

With modern day tires, flat spot is a thung of the pass. Yes it still can happen, but not as much or as severe. Chances are the tire pressure is less than optional if its been sitting. But were talking months, not just "a while"

 

LOL

 

If the wheel is not loose, my guess would be snow causing the shaking or you lost a balancing weight.

My car was shaking this morning from the snow.

 

Tires are tires, yes they have been upgraded, yes their better. But let's put your theory up against my minimal years servicing tires compared to other guys on here and I'll count up how many "new" tires have come in because they "need to be balanced" and they end up with broken belts or flat spots! Not saying that's what happened to yours but just setting the record straight

 

Not trying to argue, im just saying, flat spots dont happen as much with this day and age as they did in th olden days.

Define "new" tires as we all know. Tire ages, and as it ages, the rubber becomes hard and the sidewall no longer flexes. That could contribute to flat spot if the car sat for a numerous amount of time.

Tires have expiration date. Usually 6 years after manufactur date. So once the "new" tire passes that date, bo matter how much tread is left, its pretty much needs to be replace.

Im not saying flat spot dont happen, im saying it doesnt happen as much or as severe. And it likely wont happen if the car was park for "a while". Months yes, but not likely "a while"
