Never have done them, 420 hrs on machine, those areas at front are very well protected in my opinion and no play in those areas no problems yet, and in regard to the suspension linkages, they have numerous nice grease fittings , no problems yet.
Yes it sucks but not bad loading sleds into trailer and trying some different area's. Only real challenge is finding suitable parking area's, that are plowed and available. As more trails close more are trailering and day dropping.
