Front Subframe Mount: Service and Repair
Subframe Bonded Rubber Bushings
Special tools, testers and auxiliary items required
• Installation Device (3372)
• Thrust Plate (VW 401)
• Punch (VW 407)
• Arbor 50 mm Dia. (VW 432)
• Assembly Tool (T10214)
• Assembly Tool (T10267)
• Adapter (T10267/1A)
• Tube (T10244/3) from Assembly Tool (T10244)
Removing
- Remove the subframe. Refer to => [ Subframe, without the Steering Gear ] Subframe, without the Steering Gear.
- Install the assembly tool (T10267) - 4 - to the subframe. Secure the safety bolts using the securing pins.
1. Punch (VW 407)
2. Thrust piece (3372/1)
3. Thrust plate (VW 401)
4. Assembly tool (T10267)
5. Tube (T10244/3)
- Press out both bonded rubber bushings at the same time as shown in the illustration.
• The flat side of the thrust piece (3372/1) must face insert - A - of the assembly tool (T10267) , otherwise the insert may be damaged.
• The tube (T10244/3) has a larger and a smaller inner diameter. The subframe must contact the larger inner diameter of the tube (T10244/3).
Installing
- Bolt both bonded rubber bushings together using an original bolt, the cut outs - arrows - must align when doing this.
- Insert the bolted bonded rubber bushings, with the bolt head pointing downward, into the large diameter of the tube (T10214/2).

2. Thrust piece (T10214/3) without bolts
3. Bonded rubber bushing
4. Tube (T10214/2)
5. Tube (T10214/1)
6. Thrust plate (VW 401)
- Press the bonded rubber bushing - 1 - in until dimension - a - has been obtained.
Dimension - a - = 2 to 3 mm.
• There are two different versions of the pendulum support bonded rubber bushing: the T version - I - and the V version - II -.
• Allocation, refer to the Parts Catalog.
I The corners on the inner core - 1 - face toward the opening for the pendulum support - arrow - (T version).
II The corners on the inner core - 2 - face away from the opening for the pendulum support - arrow - (V version).
T - Version of the Bonded Rubber Bushing
- Align the tube (T10214/2) on the subframe with the pressed in bonded rubber bushings.
• The corners on the inner core of the bonded rubber bushing - arrows - must face toward the assembly tool (T10244) - 1 -.
• The corners on the inner core of the bonded rubber bushing - arrows - must lie parallel with the edge of the assembly tool (T10244) - 1 -.
Distance - a - must be identical on the left and right to guarantee parallelism.
V - Version of the Bonded Rubber Bushing
- Align the tube (T10214/2) on the subframe with the pressed in bonded rubber bushings.
• The corners on the inner core of the bonded rubber bushing - arrows - must face away from the assembly tool (T10244) - 1 -.
• The corners on the inner core of the bonded rubber bushing - arrows - must lie parallel with the edge of the assembly tool (T10244) - 1 -.
Distance - a - must be identical on the left and right to guarantee parallelism.
Procedure for Both Versions
- The subframe makes contact on the smaller inner diameter of the tube (T10244/3).
- Install the bushing all the way until a 20 kN force is reached.
1. Punch (VW 407)
2. Thrust piece (T10214/3)
3. Tube (T10214/2)
4. Assembly tool (T10267)
5. Tube (T10214/1)
- Remove the assembly tool (T10267) from the subframe and check the seating of the pressed in bonded rubber bushing.
• The outer diameter - 1 - of both bonded rubber bushings must project up to 2 mm beyond the edge in the area of the opening for the pendulum support.
• The cut outs of the bonded rubber bushings must lie at the center in the opening of the subframe.
• A gap - arrow - between the bonded rubber bushings is permissible.
- Install the subframe => [ Installing ] Subframe, without the Steering Gear.
