Hey guys new to the forum so let me start off with saying howdy. I just have a (hopefully quick) question. I picked up a 97 ls400 around august and its been running pretty well. Recently I've been getting a whining/grinding noise from the power steering. When idle or driving straight theres a slight whine but when I turn its like I let the bulls out the gate haha, its starts howling and I hear a grinding noise while I turn. I figure its a belt and maybe some bolts or pinions need tightening or whatever just thought id run it by yall first. Thanks.
