I'm getting very severe shaking of the front of my 2005 Jimny from washboard (or corrugations). I've got road tyres, the suspension is as standard and I mainly drive on highway or gravel roads, which are often in pretty bad shape from heavy traffic. The tyres are at normal pressure and I've recently replaced the front tyres due to wear, with no effect. The effect is worse under braking (as in pretty damn scary), but there is no shaking of the brake pedal. I normally would say the front shocks need replacing, but despite Jimny's being pretty common hereabouts local parts suppliers are surprised by anyone looking for these shocks as they don't seem to need replacing. Am I barking up the wrong tree?
