Hi all,

I have a Pug 206 HDI.

Basically the problem I have is when I accelerate hard, the car pulls ever
so slightly to the right, forcing me to turn the steering wheel to the left
to correct for this to stop the car wandering out of the lane on motorways

As soon as I take my foot off the throttle, the car then pulls slightly to
the left, forcing me to turn steering wheel to the right slightly to correct
this so I don't wander across lanes on the motorway.

I had bought in January 2010:
four new identical tyres (old ones had gone down to 2mm and worn evenly
across their widths)
two anti roll bar drop links (replaced as a pair as NSF ball joint had worn,
causing knocking sound)
two new front lower wishbones as knocking sound was coming from a worn bush
on the NSF)
Also at the same time, I fitted two new front discs and a new set of front
brake pads and new rear shoes. I had checked all four wheels an dthere is no
free play in the wheel bearings

The tracking was also done at the same time due to having replaced both
front lower wishbones and 4 new tyres.

Now 3K miles later, the front two tyres have gone down to 2mm on the outside
corner edges. The rest of the tread is at 6mm. I have since moved the back
tyres to the front and the front tyres to the back, and went straight to
have my tracking checked at a different garage. The garage reports the
tracking is spot on and did not need any adjustment. The tyres now on the
front are showing feathering on their outside edges.

So what else can it be if its not the tracking, lower wishbones, wheel
bearing or AR droplinks? Is the excessive uneven tyre wear and car wandering
whilst accelerating/decelerating related to each other or is it two separate
faults?

There are no discernable knocking or grinding sounds.

Regards,

Stephen

It sounds like it has a tracking fault (or the tyres would not be so worn),
probably caused by some play somewhere, my bet would be a bottom ball joint.

That was my initial thought, but the 2nd garage checked the tracking and
stated it was spot on, and they also checked for free play in the bootom
ball joints and these were ok, (remember the lower wishbones were only
replaced back in January)

I have seen pattern bottom arms worn out in just a thousand or so miles.
the reason it wanders left and right is because something has got play. it
may be necessary to do some dismantling to check everything properly.
first check though is just to get someone turning the steering back and
forth a little and look for lost motion, just like on an mot. st. column ,
steering rack, track rod ends, susp. arm bushes, bottom ball joints, wheel
bearings, suspension units themselves, loose wheels etc. etc.
