when 4C struts are dead

YV1LW · Post by **YV1LW** » 03 Jun 2022, 09:58

2006 V70R currently @ 120k. front struts replaced at 106k.

in the olden days, you could test shocks by pushing the front or rear of car up and down and watching how many cycles it took to dampen out induced displacement.

when I try and get the front to bounce, no dice.

but the rear is a different story. I can get rear to really dance and it takes several cycles for the oscillations to dampen out. Also, when going over uneven roadway, it sounds as if the rear has the hiccups.

4C system changes functions normally and no CEL or warnings in the advisory window.

I'm guessing that the rear struts, while still responding to 4C system commands have lost the ability to properly dampen the displacement.

not sure if this is really germane, but a few weeks ago loaded the back with 300# of landscape stone. seemed to have fewer strut dampening issues and don't remember hearing the "hiccup". I may be just engaging in wishful thinking but the ride seemed less 'bouncy'.

thanks for any replies!

Once you price out the 4C replacements , hiccups will be cured by the sudden gasping for breath …

An apt description HOWEVER I found a pair of rear struts for under $300 each on (drum roll please..........)

Wow, that's a low price for new. You are talking new, yes?

Are you doing the install or paying a mechanic? I have shuddered at (and avoided) doing the $C rears on on my S60R, they are still factory.

@erkiv11
I'm planning on some self-inflicted torture.

I can usually get the hardware part figured out by comparing one side to the other during the process, but plugging in VIDA and knowing where to go gets to be slightly un-nerving.
