- Place a wood block - 2 - under the subframe - 1 -.
- Remove the left and right bolts - 1 - and - 2 -.
- Remove the left and right supports - 3 -.
- Install the spindle (3346/2) , the (3301) and the nut (3346/3) approximately 1.5 cm as illustrated.
1. (3301)
2. (3346/3)
3. (3346/2)
• Turn (3346/3) on the (3346/2) until dimension - a - 4 cm is reached.
- Remove bolt - 2 -.
- Lower the subframe 4 cm only.
- Push the final drive upward over the driveshaft - 1 -. While doing this, install the press piece (T40186/1) and the spindle (T10254/5) and nut (T10254/4) (a 2nd technician is necessary).
4 (T10254/5). The spindle pins face downward.
5 (T10254/4)
6 (T40186/1)
- When removing or installing the rubber bonded bushing, make sure the spindle - 4 - does not contact the threaded hole - 3 - in the final drive.
When drilling through the inner core of the bonded rubber bushing, it is possible the (T10254/5) may not be drilled all the way through, if so, it must be drilled again.
• Drill several times in steps using a different drill bit diameter each time.
• While drilling, make sure drill does not damage the threaded hole - 3 - in the final drive; if necessary place a suitable object in between.
Wear protective eyewear while drilling.
- Position the drill - 1 - on the bonded rubber bushing - 2 - as illustrated and drill the hole in several steps.
1 - Step, 11 mm drill bit
2 - Step, 11,5 mm drill bit
3 - Step, 12 mm drill bit
- If necessary, remove the support (T10205/13) and in its place install the support with the small inner diameter - arrow - from the (VAS 6178).
- Place the tools on the front bonded rubber bushing as shown in the illustration.
1. Nut (T10254/4)
2. Thrust piece (T40186/1)
3. Subframe
4. Tube (T40033/3)
5. Support ring (T10205/4)
6. (VAS 6178)
7. Nut (T10254/4)
8. (T10254/5). The spindle pins face downward.
• Secure (VAS 6178) while pressing out.
• Bonded rubber bushing loosens abruptly. There is the risk of injuries by tools and bonded rubber bushing coming off!
Installing
Install in reverse order of removal. Note the following:
• Before installing the bonded rubber bushing, make sure the (T10254/5) is able to fit through the hole in the inner core of the bushing. When drilling through the inner core of the bonded rubber bushing, it is possible the (T10254/5) may not be drilled all the way through, if so, it must be drilled again.
Wear protective eyewear while drilling.
- Gently pre-load the bonded rubber bushing - 2 - with cover horizontally in the vice clamp as illustrated - 1 -. Be sure not to damage the outer layer of the bonded rubber bushing.
- Position the drill - 3 - on the bonded rubber bushing - 2 - as illustrated and drill the hole in several steps.
1 - Step, 11 mm drill bit
2 - Step, 11,5 mm drill bit
3 - Step, 12 mm drill bit
- Make a continuous marking - arrow - straight to the grooves.
a = 90°
• Marking is needed to align bearing with subframe.
• When pulling in the bearing, the grooves are masked by the tool.
- Coat the rubber bonded bushing with installation lubricant before pressing it onto the subframe contact surface.
- Install the rubber bonded bushing with the marking - arrow - into the subframe so that the marking points exactly in the driving direction.
- Place the tools on the front bonded rubber bushing as shown in the illustration.
1. Nut (T10254/4)
2. Thrust piece (T40033/7)
3. Subframe
4. Bonded rubber mount
5. Thrust pad (T40186/2)
6. Support ring (T10205/4)
7. (VAS 6178)
8. Nut (T102544)
9. Spindle (T10254/5). The spindle pins face downward.
- Pull bearing into subframe until stop.
• If paint damage has occurred during bearing replacement, repair using corrosion protection, primer and black top coat.
Further installation is in the reverse sequence to removal.
