Today I had a look at the wipers on my daily driver Mk5 astra. The near side one had started knocking against the scuttle panel so I had a quick internet search, mainly to find out how to remove the scuttle, and came across many links claiming I needed clips to bodge worn out ball joints, or replace link rods or the entire wiper assembly! I stripped the linkage off and immediately found play in the nearside relay arm to wiper axle. Unlike the Corsa, which are welded, the astra ones are just pressed on! Five seconds with the MIG welder and the slop is gone, the wipers work and I didn't need to spend £180 on a new assembly. Result.
