Strut mounts: centered enough?

Because there are few things in life I like more than taking apart my front suspension again...

I'm chasing a front end clunk over bumps. I'm probably just going to replace the control arms as a maintenance item at almost 130k miles, I'm trying to cover all my bases. The struts and mounts were done by me last year, so I'm not concerned about wear or damage, but I wonder if they're contributing to the noise anyway.

Driver's side



Passenger side



Neither is contacting their respective holes. Is it worth tearing into again to triple-check the clocking of the spring? I have to say the decision not to have a notch in the strut to orient the end of the spring is an odd choice.

What strut mounts are those? Where are your top plates?

Superpro Polyelasts.


I removed the top plates to inspect the orientation and take these pictures, per the FAQ.

Makes sense now.

So to answer your question, they seem to be centered adequately, which would indicate that the upper spring plate arrow is correctly facing the engine bay.

It looks like you have a little positive caster (which is good).

That is what I was hoping to hear. I wasn't looking forward to having to pull the struts again in order to reorient things. I already did the drivers side twice after I spun the shaft in the strut and killed the seal the first time around.

If it helps, I recently had a front end clunk on the driver's side. It turned out to be the lower control arm. Had that replaced (came in two pieces) and no more clunk.

Thanks. I have control arms and outer tie rods sitting in my garage, waiting for me to have time to put them in.

Based on research here, I went with Mevotech. They were better than OEM, but not ridiculously expensive.
