Summary: Cracks may develop in the trunnion to which the apex of the "a-frame" is attached. These cracks may progress to the point that the trunnion could fail and the a-frame could separate from it. If this occurs, the a-frame could come into contact with the conduit carrying air, as well as the electrical and fuel lines.
Remedy: Trunnion will be inspected for cracks and, if possible, cracks will be repaired as an interim measure. All trunnions will be reinforced by grumman; any deformed trunnions will be replaced with a reinforced part. Repairs will be performed at no charge.

Has your Flxible been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Flxible dealer can also check your VIN. Recall repairs are free.
