Pulling to left under acceleration

Dead wishbone bush? You see the same thing on 205 GTis. If one of the bushes on the wishbone goes then torque to the wheel rotates the hub around the good bush, changing the angle of the wheel. Certainly worth a look.

New wishbones in October, inc all new bushes.

Didnt do the track rod ends though
 
I'm quite enjoying this, picking out things for someone else to look at. Makes a change from freezing my bum off in the cold hurling abuse at the car. :p
 
Mine did the same and it was a worn track rod, replaced and all is fine.

Jack your front wheel up and check for any movement left to right, if there is any then put on axle stands and remove wheel, check to see if the play is coming from the track rod or the end, should be pretty obvious which one is causing the problem.

It has 125bhp, 112ft/lb ,weighs about a ton.

Left drive shaft is shorter than the right. It has an electronic differential to keep the wheels within a certain rpm of each other

I have had the car for 3 years, and never noticed it before. Its not reported amongst other owners as an issue

EDL only works at very low speeds and when it does you will hear the abs pump going.

if the car was wheelspinning anyway youd really know about that.

my small bet goes on worn bushes
 
Could be a dead engine mount, but not sure if a FWD engine can shift from side to side like a RWD one can. Definitely check all the bushes over though.

I suppose if one end was loose due to a bad mount, it could cause the engine to move at one end, in relation to the other, causing the geometry to go out...?
 
Not solved this yet!

Alignment specs are

Front

Camber -2.03 -1.57

Caster 1.37 1.38

Toe -0.01 -0.01


Rear

Camber -1.45 -1.28

Toe -0.04 -0.02


thrust angle -0.01


I have changed the tyres from front to rear which didnt make a difference.

Could the camber differences cause this? I dont think they would.

Any more ideas?
 
Driveshaft or Diff perhaps? Unsure which gearbox is fitted to the Lupo GTI, however other 1.4/1.6 VAG cars around 1998/1999 had a bad batch of diffs which tended to fail within warranty. My Bora was one of them...

Powerful FWD cars with uneven length driveshafts (which is most) can have a tendancy to pull in one direction under hard power. Go find the Top Gear clip of the Astra VXR for an example. If it's a recent problem then it's likely a fault than a design characteristic.

It isnt powerful enough to cause this, nowhere near.

As far as Im aware, no other VAG car uses this 'box, how would a damaged drive shaft cause this? If it were bent it would be undrivable surely?
 
And so the saga continues...

Now changed the front top mounts and bearings (one was split, though I was onto a winner there!) and the track rod ends to no gain.


So, to recap

Changed:

Tyres
Suspension alignment
Track rod ends
wishbones
wishbone bushes
top mounts & bearings


Seem Ok
hubs
wheel bearings




I am going to change the gearbox and engine mounts next. Any other ideas?

Well the mounts did naff all.

Im struggling to think of anything left to replace! Could the diff be damaged, so its slipping internally? No noises or anything though.
