2004 Steering Problem

Hi all, my 1.3 Doblo has developed a weird steering fault and was hoping someone here may have seen the problem before.
Basically when i am driving around the 40mph mark and accelerate hard the car pulls to the right and when i back off the throttle the car then pulls back to the left. The car is also very unstable on the motorway, i think the best way to explain it is very similar feeling as when a hgv lorry goes past you at speed on the motorway and the car gets moved off course.
There also appears to be a knocking noise/feeling coming through the steering when going over very slight bumps or uneven road.
I hope someone can point me in the right direction.
As always any help/advice greatfully received.

Regards
Barry

Re: 2004 Steering Problem

I had identical problem, mine was the bottom swivel joints, that would also account for the noise, you can either replace the lower arms or just the swivel joints

Re: 2004 Steering Problem

Hi thanks for the heads up on that, by swivel joints do you mean the bottom ball joint? Any ideas how much this is likley to cost me at the garage or can it be done diy?
Do you know if there are any posts on how to replace these?

Thanks again for your advice.

Barry

Re: 2004 Steering Problem

Hi, yes the bottom ball joints, I get through these almost every Mot, if you are going for the arms then jack up the car and support it with stands, remove the road wheel, part the ball joint, you will also need to remove the bolts holding the antiroll bar, you then remove the bolts-2 off that hold the lower arm and it comes off, for me its very straight forward but I have done this before,

the last pair of lower arms that I bought were around 50 for 2 from my local motorfactors, a pair of ball joints are about 20
Thanks TD5 thanked for this post

Re: 2004 Steering Problem

Hi,from symptoms its the front lower wishbone front bushs worn/split,allows the arm to move forward and back when accelerate/decelerate,common fault,can be lower ball joints worn but these usually produce knocking noise on uneven ground,rather than steering fault. I've had these wishbones cracked through on rear mounting as well, so I would get it checked/repaired urgently. Wishbones are available as pattern parts and if just ball joints can be got seperately as well. I would check thoroughly,as if there is perishing/splitting or wear in bushs,false economy to only replace ball joints and takes about the same time.Hope this helps,regards John.

Re: 2004 Steering Problem

All, looks like i have spoke to soon, i changed the arms and had 2 new front tyres tacked and balanced, the problem with the car pulling to right has stopped but the knocking noise has come back. Can anyone suggest a possible cause?
I was maybe thinking it could be the ARB bushes, but canot seem to source them from anywhere.
When i changed the arms the track rod ends seemed to be fine with no play in them.

Thanks in advance
