The front and rear electronically controlled shock absorbers on my 2006 XC70 are leaking oil and need to be replaced. The car has done over 320 000 km and the shocks have never been replaced. Can I replace the original electronically controlled shocks with regular shocks and by-pass the FOUR-C suspension system? If so, what shocks would fit in their place? It is an old car, and while it still runs well, I don't want to spend a lot of money on it at this stage. If regular shocks can work in place of the electronically controlled ones I want to go this option.
