2006 V70 2.5T FWD Suspension Recommendations?
 

Hello,

I am still driving my 2006 V70, now with 249,000miles. These days, I drive at least 1500 miles a month with my present jobs. It is doing very well except the suspension. Three years ago, I replaced the strut body and shock absorbers with basic Sachs units from iPD. Now it is again floating and wallowing. A quick lane change is downright frightening.
I can find no blown connectors, tie rods, other joints, other than wobbly strut braces(parts ordered).
So I am looking to re-do the shocks and struts. Getting extreme estimate differences.

The two choices I have been considering are to replace the front strut assembly with the Volvo Quick Strut Assembly that is an easy drop-in, and replaces everything, and using Bilstein Touring rear shocks. All together, that would be about $700 in parts and I could do it all myself.

The other would be to change to BC Coilovers. That would also replace the rear springs, which I could not do myself. Coilovers also require maintenance adjustments. Parts $995.00, and labor for the rear springs on this one about $400. (Mine has the shock going through the spring and a more complicated spring removal procedure than the separate set-up.)

Any input or other suggestions?

Thank you,

I've done both BIlstein HD and OEM Sachs and got 100K+ miles on both. Usually the failure point is the spring seat (see pic below). I don't think the Bilstein Touring will outlast the Sachs but the HDs will. I think coilovers is the last thing you'd want to do if you want longevity. FCP and EEuroparts ($545) may have preassembled struts for the front but I'm not sure how much they save vs having a shop with the tools simply rebuild the struts correctly. Doing the rear shocks doesn't require any special skills - worst part is moving the trunk liner to access the top mounts... If you go with Sachs, then you can start with the fronts. If you go Bilstein, I'd go with the HDs and then you'd want to do all four.
