1990 Chevrolet Suburban 1500 Problems
RepairPal has identified the most common problems with the 1990 Chevrolet Suburban 1500 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The power door lock actuators may become slow to operate or stop working completely and require replacement.
The intake manifold gasket may develop an external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
The rear axle bearings have been known to wear grooves in the rear axle shafts, creating a grinding noise and leaky axle seals. An indication that this problem has occurred is axle fluid leaking onto the wheel.
The pitman arm and/or lower ball joints may wear causing loose steering and alignment issues. Replacement of worn components will be necessary before the alignment can be properly set to specification.
