#3345 of 3420 elantra has a shimmy and cant find out whats wrong
Aug 16, 2010 (7:15 am)
i have a 2001 hyundai elantra, and i have a shimmy problem. when i do around 70-80 mph on the high way it has a good vibration to it. i have changed the tires, the cvs joint, the bearings, both rodors, ball joints, and had them balanced and alliened. also i found out that it shakes with the tires off. I jack the car up and took the tires off and ran it and it still had a shimmy with the front end. Im starting to think that its internal, not with the tires something to do with the front end.. any ideas on what else could be the problem

Check with some of the automotive windshield outfits in your area. Several around here will also do mirrors, and may actually come out cheaper that doing it yourself.

How many miles on the vehicle, and did you do inner and out CV joints, or just one end? Vibrations tend to come from the inner, and will cease as soon as you let off the throttle.
Where did you see the shimmy with the tires off? If you saw the rotor wobbling, and you already changed the rotors themselves, the hub must be bent or you have a really bad bearing!

the car has 137,000 miles. i have changes the passenger cvj joint and not the drivers side. i just changed both bearings and it still has the vibration. when i jacked it up both sides had a wobble more on the passenger side than on the driver side. it was it really a wobble more a vibration when i got around 60-80 mph.

If both inner and outer CV joints were changed, try pulling the wheel, caliper, and rotor off the passengers side. With the drivers side on the ground, apply the hand brake, chock the rear wheels and put the car in gear with the engine running and slowly let off the foot brake. This should let the passengers side axle turn at idle speed. Observe the hub and note any "wobble" to determine if the hub itself has been bent.
With all that you have changed, I cannot think of anything else that would cause a wobble in the drive train.
#3350 of 3420 Vibration when started up
Aug 17, 2010 (10:11 am)
My 2010 Elantra is only 3 months old, with <2,000 miles. Increasingly I've noticed that the car idles roughly, with a kind of vibration or slight shaking, when it's first started. This resolves once the car has warmed up. A much more subtle problem while driving, which may or may not be related, is harder to describe: something seems slightly uneven. My first thought was to check the tire pressure to see if one tire was much lower than the others, which turned out not to be the case. Could the wheels really need rebalancing on a car this new? Or is this something in the engine?

I would get it to the dealer and have them check it out. You may have a bad injector leaking down. Considering Hyundai has been using this engine for 10 years, I wouldn't be too concerned. Lot's of history and knowlege on this one, and a very good warranty, too.
Could be something as simple as a loose plug wire, or such. Have you seen a drop in fuel economy?
Just fixed an Accent (which is a totally different engine) the other day where one of the ignition coils failed. 5 minute repair, covered under warranty. I mention this because the problem first started similar to your symptoms. Weak spark caused the engine to run rough on first start (rich condition) and idle rough once warmed up.
Then the coil totally died and became very obvious!

Thanks for your reply. Hard to say if mileage is affected because the car is so new, but I suspect not; I get about 27 mpg in a combination of city/highway driving.
I figured a trip to the dealer is inevitable, but I want to know as much as I can before I go in.

My 2010 sedan is only 6 months old and my right front passenger side wheel covering is misshapen already and full of scrapes. Can the plastic be molded and/or hammered back into shape and what to do about the scrapes. Thanks for your feedback.
