REMOVAL SERVICE POINTS

<<A>> STEERING COLUMN SHAFT ASSEMBLY AND STEERING GEAR AND LINKAGE DISCONNECTION

Disconnect the steering gear from the steering column assembly while sliding the shaft A to the shaft B with the clip claw as shown in the figure is pinched.

<<B>> TIE-ROD END AND KNUCKLE DISCONNECTION

caution
  • Do not remove the nut from the ball joint, but only loosen it, and use the special tool.
  • To prevent the special tool from dropping off, suspend it with a cord.
1.Install special tool ball joint remover (MB991897or MB992011) as shown in the figure.

2.Turn the bolt and knob to make the special tool jaws parallel, then hand-tighten the bolt. After tightening, check that the jaws are still parallel.
note To adjust the special tool jaws to be parallel, set the knob as shown in the figure so that it functions as a fulcrum of the jaws.
