About one year ago I bought an 87 C30 with about 170,000 miles.
I have used it little, put on about 1,000 miles.
About 100 miles ago, the steering would tend to lock up occasionally.
Now, it seems to be permanently locked. When the steering wheel is
turned left or right, it only turns about 10 degrees either way and it
stops. When it stops, there is a loud squeal.
The squeal is coming from the power steering pump. The pulley
pretty well stops. It (power steering pump) also tends to squeal
when brakes are applied. The belt seems to be sufficiently tight.
What is going on?
