Hi. I'm the new owner of a 1999 Hyundai accent. It's only got 21k on
the clock, with little wear and tear, and has had a service every year,
including a new timing belt last year but......it's starting to vibrate
quite badly. It's noticeable at any speed, but particularly bad between
45 and 55 mph. It improves after that, and isn't too noticeable until I
exceed 75mph, when it returns.

I'm a bit thick* when it comes to car fault diagnosis, so any advice
or suggestions would be greatly appreciated. I can't see any damage to
wheels or tyres, but with the previous statement in mind, I probably
wouldn't see a problem if it was there.



*I'm being kind. for 'bit thick' substitute 'utter, utter moron'.

Thank you.
