I have an 87 300 SDL. 255k
About 4 months ago it started making a howling noise when I made slight (very slight) drifts to the right and would get louder the more I turn to the right.... Then it dissappeared untill last week. It is back!

Any ideas of what it might be? I am thinking maybe bearings... Ideas please.

Thanks much
