Tie rod replacement

Only tie rods with harder rubber mounts (optimized tie rods with spherical mounts) - version (B) - are still available from the Parts Service.

Introduction of the optimized tie rods in the current model year 1999 (X) in some cases, but generally from model year 2000 (Y).

Part No. of the optimized tie rod: 996.331.045.10. These tie rods may be retrofitted - but only in pairs.

In general, the following applies: Only tie rods (toe control arms) of the same version - A or B - may be installed in a vehicle. In the case of replacement, replace both tie rods if necessary (install version B). 

Visual distinguishing characteristics between tie rod versions A and B: 

• The cast number (refer to Fig 1 ).
• The metal bushing of the rubber mount. On version A, the metal bushing of the rubber mount is flush with the tie rod. On version B, the metal bushing of the rubber mount projects slightly - by approx. 1 mm - at both sides (arrow).
