Heavy steering and chattering pump

chrisstdt · Aug 28, 2017

My series has power steering fitted ,RRC 3 bolt box connected to a 300 tdi pump

Box had weaped for a while but steering was fine ,then the steering went heavy and the pump would chatter when turning so i changed the pump which made no difference

I changed the box for a good used one at the weekend which stopped the leak but steering is still heavy !

When the front wheels are jacked up steering is light and when the steering bar is disconnected i can turn the wheels easily by hand and everything feels smooth

Any suggestions ?

Read a post once about hydraulic hoses delaminating or similar inside which caused a blockage in the hose?

Got it sorted i found theres a 1/2" bolt on the top of the box to bleed it

Cracked the bolt off turned steering lock to lock ,bubbles came out and shes sorted
