"This Volvo 940 Turbo control arm is sold with the upper bushing pressed in."

This is an excerpt from the description on the FCP Groton site for the control arm stay. The illustration would not copy, but this is the arm that runs from the area at the rear of each front wheel back to the frame member at a 45 degree angle.


It is number 18 in the illustration and here is the link:

I'm not sure how to give a clear explanation of what and where this piece is, but it is the stay rod, which everyone seems to point to as a source of wheel braking shudder.

In my case its very likely because the two cone shaped bushings at the forward end of the pipe were completely worn out; torn and shredded.

However, the upper bushing (#9 in the Groton illustration)looks remarkably intact. It looks so good, in fact that I'm considering using the original control arms and just replacing the two bushings on each that I have in my bushing kit from IPD. I opted for the more expensive option from IPD, which includes the upper bushing and I would consider replacing those too, since I have them, but it looks to be a real challenge to remove the existing bushings from the stay rod and then an equal challenge to insert the new bushings in the sleeve.

IPD made it sound like replacing the bushings from the kit was a definite do it your selfer type project, but from what I can see, unless you have a press, which I don't, removing the upper bushing is near impossible. And then again, the bushing that is there looks absolutely fine. The stay rods appear to be original with the car, which now has 194,000 miles.

[Just for informational purposes, removing the forward facing bolt required super strength and a 24 inch breaker bar. I was successful with one. On the other the pipe portion that is threaded to receive the bolt sheared off. In hindsight, I should have used a torch on the bolts before attempting removal.]
