power steering bad vibration
hi all
well over the last few weeks when driving my car has serious vibration when steering wheel is turned even coming out of a junction then sometimes just pulling on to the drive when steering wheel is turned slightly . do you think the problem is ATF wants changing or is it something worse i got the front end of the ground today with engine running i turned steering wheel full lock both ways and the problem was there while the engine was running i gave one of the wheels bit of a kick and it stopped .but started again on test drive it seems to do it if i go over uneven surface too . no oil leaks . any help please |
Sounds like either a steering rack or pump issue. Hard to diagnose online, maybe someone else will chime in.

hi yes pretty sure its one of those .
if i change the oil could that cure it ? |
It sound like there is air in the line . If there is air in the power steering system it will vibrate . Much like break lines the system needs to be bled . If this doesn't correct it then there must be something else wrong with the system. I just sent my ZF rack off and had it rebuilt .

hi smokeyja
how do you bleed your power steering is it just by disconnecting the upper hose on the top up tank ? |

PS pump tricking me out
What`s the news?
Now that I changed the left engine mount today, ps pump started vibrating a little more than it did before. I remember it wasn`t vibrating that much before. (All ps bushings are new, so that`s not the case, also, bracket passed visual inspection for cracks, no cracks, upper adjuster bar NOT bent) I just painted the pulley, pump was removed, belts off, (+new motor mount today)so I might just have to loosen it up again and tighten back everything, worth a try. |

well at last logged back in .
good news my steering problems are now fixed after my mechanic changed the steering pump . and then the steering rack so it proved to be a faulty rack in the end i hope well no problems for the last month and a trip to ireland too . thanks again for your support on this forum |
I would say you have a bad pump, if you ran the pump for a long time low you more than likely burnt the seals out of the pump and should have it replaced.
