-
Steering wheel/handle bar (steering)
Certain vehicles may be subject to steering shaft separation due to loose set screws in the dash sheet bearing which may allow the shaft to move.
Remedy: Dealer will inspect and modify the steering shaft by providing a greater slip length in the steering drive shaft to eliminate slip joint separation.
-
Hand control/valve (service brakes)
The retaining pin for the brake control knob has been misaligned (off the center line of the valve plunger hole). This causes the knob to be overstressed at the retaining pin hole area causing it to separate from the valve.
Remedy: The holes will be retooled to provide correct alignment and plastic knobs will be replaced by knobs of stronger material having metal reinforcements.
-
Air (parking brake)
On certain vehicles, the knob that operates the tractor park valve may break off, rendering the valve inoperable.
Remedy: Defective knobs will be replaced with an improved type, without charge to owner.
-
Gear box (other than rack and pinion) (steering)
The prefabricated pinch bolt clamp at the lower steering shaft lower yoke may not perform adequately when tightened to specifications. The clamp may then deform and loss of clamping force and steering shaft disengagement may result.
Remedy: Dealer will retrofit with lower steering shaft lower yokes that provide for integral pinch bolt installation in place of previous separately fabricated clamp for the pinch bolt.

Checking a specific 1980 Mack U Series
How do I know if my 1980 Mack U Series has an open recall?
Enter your 17-character VIN above. The VIN is on the driver's side dashboard (visible through the windshield), the driver's door jamb sticker, and your registration or insurance card. The check runs against NHTSA's live database and tells you which campaigns list your vehicle. 4 campaigns currently list the 1980 Mack U Series; your car may already have been repaired under some of them.
Is the recall repair free?
Yes. Under federal law, manufacturers must fix safety recalls at no charge for vehicles up to 15 years old from the date of sale to the first owner. Contact any authorised Mack dealer with your VIN and the NHTSA campaign number (for example 80V052000).
What is the difference between a recall and a complaint?
A recall is a safety campaign filed by the manufacturer or ordered by NHTSA, with a defined defect and remedy. A complaint is a report an owner sent to NHTSA; it is not verified, but patterns of complaints are what trigger NHTSA investigations and, eventually, recalls.
