Not sure if this shoild be in the gen section, but
does anyone have a parts list for these suckers, alternatively the ball joints for the front steering assy... does anyone know if there is a common replacement as on of mine is buggered:(
alternatively has anyone modded this setup using replacement ball joints?

any help much appreciated

According to my copy of the manual.

642837-9 Guide pin

The lower ball joint part No's are:

Edit - go to Volvo truck place for spares, not to volvo car dealers.
