Trick 17? 2/09/R. Kwas
Huh?
-----------------------------------------------
122 Trailing Arm Bushing Bolt Removal...Last Resort because bolt must be sacrificed! Cut Head (27) from bolt (doing as little damage as possible to axle tube tabs or trailing armas possible!) and using a nut (a non-nylon locking preferred, if available, but not critical), draw remains of bolt out...use graphite grease (or AS) on threads and bearing surface of nut to decrease friction (AS Mech 3A)...threads are not continuous on entire bolt-shaft, so it will take several repetitions of removing nut and adding a stack of washers for spacers to make irresistable force to extract the entire bolt-shaft. After head of bolt is removed and before beginning to apply pulling force with nut, spray penetrating oil into clearance. Once shaft starts moving, spray more penetrant into hole in alu core to wick into alu-oxide between bolt-shaft and alu core. [This strategy can naturally be adapted and used as a last resort for other through-fasteners.]

(Simplified) detailed X-ray view of assembly. Alu bushing core actually
contacts axle tabs. Rubber, which is effectively between tabs and trailing
arm, isolates these from each other.
Detail showing Bolt-shaft removal.
Bolt must be sacrificed, but nut can then make irresistible removal force!

122/1800 Lower A-Arm Pivot Bolt Removal:
122/1800 Lower A-arm detail showing the long pivot bolt (53) which passes
through sleeve in crossmember and likes to become one with same...Trick 17 is
effective in removal once all other attempts have failed...
Wouldn't it be nice if cars were assembled with AS?
