Forreste dæmper

[Michael.N.]

Jeg har for nylig skiftet den venstre forreste hydraulik dæmper, da den gamle var utæt.
Jeg har så købt en brugt, men den hakker gevaldigt, både ved kørsel samt når Jeg starter bilen.
Ved start hopper den op i ryk, men kun i ved den "nye" dæmper.
Nogen der ved om de skal udluftes ved skift eller om der er andet man kan gøre?
Mvh Michael

n principle, the LDS system is self-venting. However, the following should always be carried out when replacing hydraulic elements.
1. check the LDS level professionally - lowest position by diagnosis or by manual depressurisation.
2. raise the vehicle several times to ‘Max’ and lower it to ‘Min’ and also turn the steering several times by moving it from one stop to the other without hesitation.

If you drive for a longer period without this bleeding procedure, anomalies should stop on their own. This is more likely to be a functional problem with the installed spring element.

Addendum:
After the suspension strut has been replaced, it could also be the result of improper installation, which leads to distortion. In particular, the lower swing arm may only be tightened in an exact height position that corresponds to the normal ride height.
Or the transmission of the height sensor on the front axle is not running smoothly because it has not been oiled or has become bogged down.
