Lower support of the car "Toyota 4-Runner/ Hilux/ Surf"
1. Lower support; 2, 4. Cotter pin; 3. Steering rod; 5. Lower arm; 6. Fist
Checking the play in the lower ball joint
1. Not more than 2.3 mm
Examination
The condition of the ball joints should be checked every time the vehicle is lifted.
1. Raise the front of the car.
2. Clean the supports and check the condition of the seals.
3. Raise the vehicle by placing a jack under the lower control arm to relieve the load on the support.
4. Rock the wheel with a tire iron while checking the play in the support (performed with an assistant). If the play is significant, replace the support (see fig. Checking the play in the lower ball joint).
5. Rock the upper support. Replace the support if significant play is detected.
6. The support should be checked each time the knuckle or supports are removed.
7. To check, try to turn the support pin by hand.
8. If the finger can be turned by hand, replace the support.
9. The manufacturer recommends a more accurate method.
10. Rock the support pin away from you and towards you 5 times, then tighten the nut.
11. Using a torque wrench with a scale of several Nm, check the moment of resistance to turning the pin.
12. Turn the pin with a key, making 1 revolution in 2-4 seconds. On the 5th revolution, check the torque readings and compare with the standard (see subsection 9.1).
13. If the moment differs from the norm, replace the support.
Replacing the upper support
1. Remove your fist.
2. Remove the clamp, cover and take out the retaining ring.
3. Press out the support using a puller through a mandrel (1 – deep mandrel).
4. If the joint itself is being replaced, press it in with a hydraulic press through 2 mandrels (1 – mandrel).
5. Then assembly is carried out in reverse order.
6. Tighten all suspension fasteners to the specified torque.
Replacing the lower support
1. Disconnect the steering rod.
2. Disconnect the knuckle from the lower arm.
3. Loosen the bolts and remove the lower support.
4. Install the new support and tighten the bolts to the specified torque.
5. Then assembly is carried out in reverse order.
