I'm rounding up the parts to reseal the upper gearbox (280 leg ) and I'm getting conflicting answears, the local parts people said that I really don't have to replace the yoke screw, if it's not damaged, but the shop manuals say I should, ( my feeling is that when you tighten the screw you'll stretch it, and you don't want to use it again )and to add to the issue , Volvo has that screw on back order, with no shipping date ... my supplier say's they can't get an answear ... as to a ship date
