Dayhuff v. General Motors Corporation, 303 N.W.2d 179, 103 Mich. App. 177, 1981 Mich. App. LEXIS 2690 (Mich. Ct. App. 1981).

Opinion

Per Curiam.

Defendant General Motors Corporation appeals as of right from a jury verdict against it in the amount of $250,000 for Cindy Dayhuff; $1,690.48 for Gerald Dayhuff, individually; and $420,000 for the estate of Flossie I. Dayhuff.

This action arose out of an automobile accident which occurred on June 11, 1971. On that date, Flossie Dayhuff was driving the DayhufFs 1970 Chevrolet station wagon north on 1-75 freeway with eight passengers. Just after they passed a semi-trailer, Flossie Dayhuff lost control of the car, it swerved into the freeway median, started to skid sideways, and then rolled over three times. Flossie Dayhuff and Sandra King were killed in the accident. It was later discovered that the left rear wheel had separated from the car when the enlarged holes of the wheel spider allowed it to come off over the lug nuts. The cause of that condition was the main contested issue at trial. Plaintiffs sought to show that the axle flange was convex causing improper wheel contact which allowed motion to enlarge the wheel holes. GM sought to show that the wheel lug nuts were insufficiently tightened causing the same condition.

*181 On appeal, GM seeks judgment n.o.v., alleging that plaintiffs did not establish that the bent axle flange was a defect attributable to the manufacturer and that it was a proximate cause of plaintiffs’ injury.

A plaintiff in a products liability case has the burden of establishing that the product was defective when it left the manufacturer. He is not, however, obligated to eliminate all possible causes of the accident consistent with the view that there was no manufacturing defect. He sustains his burden when he establishes with direct or circumstantial evidence a reasonable probability that the defect is attributable to the manufacturer. Holloway v General Motors Corp (On Rehearing), 403 Mich 614, 621; 271 NW2d 777 (1978). Questions of comparative probability are to be resolved by the trier of fact. Id.

We first note that judgment n.o.v. is appropriate only if the evidence is insufficient as a matter of law to support judgment for plaintiff. In reviewing such a motion, we must give the nonmoving party the benefit of every reasonable inference that could be drawn from the evidence. If reasonable minds could honestly disagree as to whether plaintiffs have satisfied their burden of proof, judgment n.o.v. is improper. Cormack v American Underwriters Corp, 94 Mich App 379, 382-383; 288 NW2d 634 (1979).

Plaintiffs’ evidence showed that the Dayhuff vehicle, which had been purchased from Vic Ca-never Chevrolet, Inc., had pulled to the left from the time it was new. Gerald Dayhuff returned the vehicle to the dealer numerous times seeking a solution to the problem. At 1,000 miles the rear tires showed excessive wear. Dayhuff was instructed by the dealer to place more weight in the *182 car. At 5,000 miles the left rear wheel was worn enough to be unsafe.*Dayhuff replaced it with the spare wheel. When the spare wheel and tire were removed from the car, a rejection tag which referred to a defective axle was found tied to the car underneath the spare. Dayhuff met a GM representative, Joseph Stanzel, at another dealership which examined the vehicle’s rear end. Dayhuff testified that they had discovered that the car was out of specification and that they had written a service order to replace the entire rear end but then changed their minds and claimed it was repaired after they had worked on it. Dayhuff testified that the car still pulled to the left. When he returned it again to Vic Canever Chevrolet, he was told that the tires were at fault.

Dayhuff then took the car to a Firestone tire dealership which examined the tires and found nothing wrong. Dayhuff again returned to Vic Canever Chevrolet without result. He testified that the left rear tire was worn very badly and the right rear tire was also wearing but the front tires were in very good condition. At approximately 15,000 miles Dayhuff had the two rear tires replaced at the Acme Auto Store. He testified that the car still pulled to the left.

Plaintiffs’ expert witness, David Felbeck, examined the left rear wheel and took pieces of the failed metal to an electron microscopist for examination. In the resulting pictures, Felbeck found fatigue striations which are characteristic of a force with high and low and reverse cyclic variations over time. The striations indicate that the wheel was subjected to many, many stress cycles during the growth of the cracks — meaning that the car had been driven many thousands of miles. Felbeck then examined the left rear axle flange *183 and found that the flange was not flat but was evenly distorted .024 inches in a conical shape. He made a stress analysis and tested the hardness of the flange in order to determine whether it could have been plastically deformed by some force applied on the circumference of the flange. He concluded that the force required to distort the flange would be 12,200 foot-pounds. He examined the flange and the whole axle to determine where and how such a force could have been applied. Since he found no damage of any kind to the relatively delicate surfaces of the flange, he concluded that it had to have been bent at some time prior to installation on the car. In Felbeck’s opinion the wheel became progressively weakened because of the development of fatigue fractures around the lug bolt holes and wobbled or came off causing loss of control.

Jay Bolt, a mechanical engineer, testified on behalf of plaintiffs that the left rear axle flange was convex, which meant that the wheel spider had to be deflected some amount before the wheel could make contact at its outer contact circle. If the lug nuts do not provide sufficient pressure at the outer contact circle to transmit the torque which drives the car, a gradual motion will develop and a loosening will occur. By doing three tests, he found that it took 30 foot-pounds of torque to achieve outer contact with the flange (on a normal flange contact would first be made at the outer contact circle). He stated that normal specifications call for 70 pounds of torque to tighten the wheel to the flange. He testified that if one applied 70 pounds of torque to the nuts over this bent flange normal contact force would not be achieved since 30 pounds of the torque would be used up in deflecting the wheel to conform with the deformed *184 flange. In his opinion, due to the convex flange, insufficient force existed at the outer contact circle on plaintiffs’ car. This could have allowed a slight motion to occur, leading to stress and cracking of the bolt holes, and ultimately, to wobbling which could have led to a loss of control. In his opinion, the flange was manufactured in the convex condition, but he admitted that it could have been bent in the accident.

We conclude that judgment n.o.v. is inappropriate in this case because reasonable minds could honestly disagree as to whether plaintiffs had satisfied their burden of proof to establish a reasonable probability that the defect was attributable to the manufacturer and that the convex flange was the proximate cause of plaintiffs’ injuries. Thus, the questions are within the province of the jury. This case is not like Kupkowski v Avis Ford, Inc,
