Installing Tie Rod

Information 

• Install in reverse order. 
• The tie rods are delivered preset as an assembly (tie rod/tie rod joint). 
• If the joint boot is to be used again, before installing inspect for wear (cracks, slits) and check that sealing surfaces are clean. 
• Identify position of tie rod joint on the (pre-) set tie rod and, in order to fit the joint boots and the small clamp, remove/fit lock nut and tie rod joint. 
• During installation, insert new sealing rings on the steering gear. Take care not to damage the sealing ring when fitting the joint boot.

When fitting the large clamps, it is essential to observe the following installation position (right/left). The clamps must be fitted at the correct position. Place the pliers for lug hose clamp Nr.74  on the clamping washer lug and lightly clamp. It should still be possible to turn the clamps easily. Check the position of the clamp once more, correcting if necessary, and then compress the clamp lug fully.

The clamp on the left joint boot must be clamped on the steering gear so that the clamp lug is in line with the steering shaft! Failure to observe this can lead to constrictions in the area of the supply and return lines.

The clamp of the right joint boot must be clamped on the steering gear so that the clamp lug points horizontally with the front axle carrier (suspension sub-frame) in direction of travel. Failure to observe this can lead to constrictions in the area of the heat shield.
