Haberling began his racing career in the early 1950s in the American Midwest where he competed at numerous track events racing stock cars and hot rods. He later competed in three AAA Stock Car events in which his most notable starts were in Richmond and Milwaukee. He returned to Phoenix, Arizona in the late 1950s to continue racing in supermodifieds and raced alongside future Indy legends Roger McCluskey and Don Davis along with Hank Arnold and Gene Brown.
On February 21, 1961, Haberling was practicing in his 1955 Chevrolet in preparation for the 1961 NASCAR Sportsman Modified 250 mile race at the Daytona International Speedway when tragedy struck. Having entered the east turn, Haberling's Chevrolet spun sideways, veered down the 31 degree banking, and ran it up again before rolling over several times and coming to a stop near the infield grass. The real cause of how the accident started was never known. The car was destroyed in the accident;[2] Haberling died instantly of massive injuries, his helmet was also torn off in the accident. He was the chairman of the board of directors for the Arizona Roadster Association and was ranked 6th in modified sportsmen points at the time of his death.
Haberling was survived by his wife, Betty Jean (1927-2009), and their three daughters. He was buried in Greenwood/Memory Lawn Cemetery in Phoenix, Arizona, very close to the graves of two other Phoenix auto racing legends, Jimmy Bryan and Bobby Ball, who similarly lost their lives as a result of auto racing accidents.
