1990 GMC 2500 Pickup Problems
Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.
The inside and outside door handles are prone to breaking.
The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.

is a 1993 gmc 1500 compatible with a 1990 gmc 1500 ??? motor wize body and interior ???
I love my old truck, but it started leaking power stearing real bad. I started puting Lucas power stearing stop leak fluid in it and then sometimes when I first started it, the stearing wheel will jump and once it wouldn't turn at all.
Once it freed up, it drove fine, but I am worried that it might freeze up while I am driving and cause a wreck. Is that a possibility?
Is this a bad pump, gear box or just air getting in the system?
