Looks like my 06 GL needs a new front strut. The other side was done 25k miles ago by MB so should have plenty life yet. The MB replacement is a Bilstein unit. The original has 150k on it so has done well but is shot. Do MB do exchange units for these. Bilstein are £700 from AUTODOC which is a bit pricey. Any opinions on the cheaper alternatives? I replaced the rear shocks with cheap copies which are fine but the fronts are far more complex so I’m a bit dubious about going down that route for the fronts. Have airdominance gone bust?
