Cool Rear suspension condition -uncoiling sound

I'm learning about and assessing the condition of my rear suspension on my 98 Pathfinder. I posted about this earlier, but solved part of the "creaking" problem.


So, while under the truck I noticed a lot of rust on the Springs and Shocks. Do they look okay in my photos (link below). Also, what are the loose, rubber tube-things in the middle of each spring? They are rolling around on their side. It doesn't look right. What are these things and should they be attached to something ?

Check out the photos I took... Car photos - 98' pathfinder

Could they be at the source of an intermittent "boom-Ka-chuuuung" sound I hear from the rear, when I come off a speed bump or curb? It's like an uncoiling sound that lasts 1 second.

If I take it to the mechanic, what might I ask him to do (if anything)?

Thanks
Jake

The muffler hanger could be the source of some of the noise you have been hearing. You may be able to reposition it away from the frame where it's striking or put a small piece of radiator hose on the end of the hanger.

The rubber block inside the spring is probably a "bottom out" block of rubber to provide a stop for the compression of the coil spring. It needs to be set upright and attached. That will probably take a new part and some $ for labor to get that done.

Thanks - everything you wrote make sense to me.

Curious, when you looked at the photos on my webpage, did you see a video running of the striking sound?
