Inner Tie Rods



Disassembly of the rack and pinion assembly requires special tools and skills. Before attempting this time consuming and difficult procedure, check on the availability of already rebuilt rack and pinion assemblies. You may find it more cost effective to purchase a rebuilt assembly from your local parts jobber.
