A removable heat shield mat was installed on the steering gear at start of production. Be sure to install this mat if installing the old steering gear again.
A removable heat shield mat on the steering gear was replaced by a bonded heat shield mat as a running change. It is therefore not necessary to take the mat from the old steering gear and installing on a new steering gear.
A replacement steering gear comes with the bonded heat shield mat.

Tie rod end check dimension
- Place a steel ruler -2- on the tie rod end and push it all the up to the edge -arrow- of the tie rod end -1-.
- Replace the complete steering gear with the tie rod and tie rod end if the check dimension -a- is less than 188 mm.
Tensioning the Inner Clamp
- Mount the CV Joint Boot Clamp Tool-1- as illustrated. Make sure that the jaws of the clamp tool are seated in the corners -arrows- of the clamp.
- Tighten the clamp by turning the spindle using a torque wrench -2- (do not tilt the pliers).
- Use torque wrench -2- with 5 to 50 Nm range (for example, Torque Wrench 1331 5-50Nm -VAG1331-).
- Make sure the thread on the spindle -1- is easy to move. Lubricate with MoS2 grease if necessary.
- If difficult to tighten, for example because of dirty threads, the proper clamping force of the clamping sleeve will not be reached even when tightened to the specification.
