1991 Ford Bronco Problems
If there is a vibration or noise at highway speed, it could be from the front driveshaft and may require replacement of the double cardan joint. A double cardan joint is a type of driveshaft joint that uses two universal joints.
If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing deferential clutch kit. An updated differential clutch kit available.
The front brakes may stick, bind, or grab. This can happen when the front brake caliper pins become corroded. Cleaning or replacing the caliper pins will be necessary to correct this problem.
The upper intake manifold gasket may fail, causing an engine vacuum leak and a high idle condition. A damaged intake gasket should be replaced.
