Steering Wheel Shaking at 65+
 

I just bought a 2003 Boxster which drove ok until I hit 65+ mph and the steering wheel shook. I had the front wheels balanced twice and put new front tires and it still shook. I have Hankook Ventus Sport K104 235/35/19 in the front and 265/30/19 in the back. The mechanic said that Hankook are cheap tires and are the cause of the shaking, but he was wrong! These tires stick to the road! Today I took my boxster in to America's Tire Co to get a Road Force Balance on the front tires. Big difference... The car drives like a Porsche should. It cost $20.00 per wheel. If the wheel has to be dismounted there is an additional $7.00 per wheel.

Hi,

It's amazing to me that anyone would even consider driving their car without all the Lug Nuts in place, properly torqued... HELLO - They Hold The Wheels On!

Happy Motoring!... Jim

Whew....I'm glad it wan't only me that thought this! :cheers:

For many people, that is why they drive a boxster. Feedback is good! 18" wheels, M030.. it should be "stiff". Then again, maybe another Corolla would be more appropriate,

As for vibration, I would get all lug bolts installed and torqued to the correct tightness. I would encourage a "road force" mounting/balancing. It is concievable that after some miles the tires can become "unbalanced". Also, it could be possible that a wheel weight has come off a rim.

lug nuts are over rated... So is correct tire pressure and wheel alignments.
What's next? buying one of those silly torque wrenches?!
You Porsche guys need to chill out and have faith that nothing will go wrong.

Hey Jim! Good to see you back around. I thought we'd lost you for good to that scooter!
