Hi guys I'm new the the forum. I have a case 1838 and when turning left and right there is a somewhat loud whining noise when turning. But driving forward and reverse and lifting and dumping the bucket there is no noise or whining. I wanted to know if this is something wrong within the hydraulic system or could my drive motors be going bad? Any insight to this issue would be appreciated. Also I am running 10w30 in the hydraulic tank without HTO additive.
