So we got some questions about our recent discussion on steering assist. The questions was, why only to the right?

The answer is that it can be to either side, that just happened to be the the example we used. If you are getting no assist to just one direction, left or right, then it is the rack valve.

If you are getting no assist or too much assist to both directions, it could be the rack, but more likely it is the steering pump. The pump does not know which way you are going, so if it happens to both sides, usually the pump is to blame. Larger shops have a steering pump tester to measure the pressure, this will quickly tell what the problem is.
