Mechanic claimed I needed a new control valve; when I got the car back the steering vibrated when turning. They then claimed it was now the steering cylinder. Replaced that. Same problem. I've had this car 30 years and I don't think it needed these parts; the whole front end, with all steering components (except gear box) had been done a few years previously. It also has a new pump. I heard that the company that was making the control valves was turning out defective parts for a while. Then I noticed that the mechanic didn't put any of the bushings on the steering cylinder. I got the kit and did that, now the wheels shake uncontrollably even when not turning the wheel. So is it the ram or control valve malfunctioning? It appears the hoses were hooked up right, but if a hose is defective, (they didn't put on the new hoses I gave them) which one would cause this symptom? I am so frustrated and disgusted - I want my car back on the road!
I sounds like someone really made a mess for you and you will have to go through it by process of elimination.
You might just hjave an alignment problems or there is a loose front suspension component. The best place to start is to have an alignment done to rule out any alignment issues and they will identify any loose or missing components during the alignment as well. So, for your situation it will be well worth the money even if it just eliminates a few things. However, more than likely things like this come out in an alignment and they will diagnose it while aligning it.
I don't think you needed any of those parts either unless you hit a curb really hard.
