IIRC question

[ukrkoz]

2011 QX56.
Question: IIRC appears to be integrated into the shocks. I understand, it's levelling system but - because it's built into shocks, or so it appears, does it have any influence on shocks function?
Is it supposed to be serviced on a regular basis? Mine has 155 K miles and I'm pretty sure, IIRC was never serviced, truck was owned by Asian gal.
Basically, is it worth taking it to dealer and paying $900 to change oil in it and reset pressure to improve ride quality?

If it were mine, I'd replace all the struts with this:

My guess is, you won't get out of the dealership for $900, considering the age of the system. Worth taking it in for an estimate, but I suspect you'll be "shocked" at the results.

They gave me over the phone estimate for "what we call meter service" part of which is servicing that system. $840 + tax.
To be honest, not worth it. Truck is sold around here for about $8K average, not dumping thousands into it.
