Former Fruehauf Corp. chief execitve Neal Combs, who ran the company when it was dismantled to meet leveraged buyout debts, has been replaced as head of its truck-trailer operation. Combs was replaced Tuesday as Fruehauf Trailer Corp.'s chief executive by Terex Corp. President Woodward Baldus, officials said. Green Bay, Wis.-based Terex bought Fruehauf's trailer business last August as Fruehauf assets were sold off to meet debts from a $1.5-billion leveraged buyout by management. Fruehauf Trailer Corp. continues as a Terex subsidiary. Combs went to Terex with the trailer business. Combs could not be reached for comment Wednesday at Fruehauf or at his home. ``Combs was asked to resign,'' Terex spokesman Jeff Zilka said, but declined further comment. The last of the former Fruehauf's assets, Kelsey-Hayes Co., maker of auto parts such as aluminum wheels and anti-lock braking systems, was sold to Canada's Varity Corp. last November. Fruehauf Trailer employs about 5,100 people in its U.S. operations.
