i have a Hyundai coupe '99, 2.0L. CAT D.
i have a problem, whenever i go 70mph and 3.5rpm the steering wheel vibrates so violently its a struggle to hold it, at a higher speed or rpm its smooth and lower speed or rpm its smooth.
my old 1.2L use to vibrate alot at bout 80mph because that was its top speed but this hyundai should make almost 125mph.
ive had numerous wheel checks such as balance, tyre pressure, tyre wear, alignment, tracking etc etc, all still with no improvement.
was just seeing if anyone has had similar problem/ knew a fix or what to check.
