- Car front also establish to Poddomkratta it on the props got under a frame.
- Establish a jack on the center of a case of the forward bridge and cock it, having unloaded shock-absorbers.
- Disconnect the lower support of the shock-absorber from a spring step-ladder plate, push the shock-absorber up, having taken away it from a bridge case.
- Lower the bridge, having removed weight from springs, give nuts of U-shaped bolts of a step-ladder and remove a basic plate.
- Turn off fixing nuts and remove fingers and plates of an earring from the forward end of a spring.
- Give a nut and a bolt of fastening of an anchor finger since the back end of a spring. Remove a finger and take a spring from under the car.
- Remove with a wire brush from sheets of a spring all dirt and traces of corrosion. Examine sheets of a spring on existence of cracks and it is erose. Check durability of installation of the central bolt.
- Check rubber plugs, earring fingers, an anchor finger and the limiter of the course for existence of signs of wear and damages. Replace defective components.

Authors of this manual recommend to make in all cases replacement of springs of a suspension bracket in pairs even if only one of them is faulty. |
Installation
Installation is made upside-down.
|
|
- Do not tighten a nut of U-shaped bolts of a step-ladder with the effort exceeding 118 Nanometers as at the same time there can be a deformation of a spring to landing arms of the bridge or cutting of U-shaped bolts. You make tightening of nuts with the required effort evenly, in several stages and you watch correctness of provision of a basic plate.
- Do not tighten a nut of fastening of an earring, an anchor finger and the lower support of the shock-absorber until all weight of the car is not postponed for its wheels. It will help to avoid excessive loads of rubber plugs upon transition them into position.

Replacement of an anchor finger of fastening of the back end of a spring and its plugs
|
|
Replacement of rubber plugs of anchor fingers of springs of a forward suspension bracket can be made without removal of springs from the car. |
|
- Car front also establish to Poddomkratta it on the props got under a chassis frame.
- Establish a jack on the center of a case forward the bridge and cock it, having hung out the forward bridge and assemblies of springs.
- Give fixture (a bolt with a nut) an anchor finger since the back end of a spring.
- Take rubber plugs from a spring.
|
|
|
|
|
Installation is made upside-down.
- Previously grease plugs with lubricant for rubber components.
- Tighten a nut of fastening of an anchor finger with effort of 76 ÷ 102 Nanometers, and a fixing bolt - with effort of 11 ÷ 15 Nanometers after the weight of the car is postponed for its wheels.
|
|
Final tightening of all fixture with the required effort has to be made surely after transfer of weight of the car on wheels, otherwise plugs in use of the car will be exposed to excessive loadings. |

|
- Car front also establish to Poddomkratta it on the props got under a chassis frame.
- Establish a jack on the center of a case of the forward bridge and cock it, having hung out the forward bridge and assemblies of springs.
- Give fixing nuts and remove assembly of an earring from the forward end of a spring and an arm of a suspension.
- Take rubber plugs from a spring.
- Installation is made upside-down.
- Previously grease plugs with lubricant for rubber components.
- Tighten fixing nuts with the required effort.
