 Attention! For repair performance you will need a stripper of springs. Do not try to remove a spring without stripper — you can suffer a serious injury and damage the car.

If you found out that the rack is faulty (traces of leak of working liquid on its surface, breakage or sag of a spring, loss of efficiency of clearing of fluctuations), it should be sorted and repaired. Racks in itself are not subject to repair and at an exit from costing to the shock-absorber them it is necessary to change, but to replace springs, and components having relation to them, it is necessary in pairs (on both sides of the car).
2. Remove a rack (address the Section Removal and installation of a forward support), place it on a workbench and clamp in a vice. Remove all dirt from its surface.

3. Squeeze a spring by means of a stripper, having completely taken off pressure of a plate. Reliably fix a stripper on a spring (follow instructions of the producer of a stripper).

Put a rack vertically and check its working capacity, feats a shock-absorber rod at first from an emphasis against the stop, then the short movements on 50-100 mm. In both cases movement of a rod has to be uniform. At emergence of breakthroughs or jammings, and also at any other signs of malfunction the rack should be replaced.
