can anyone advize me please.
I have just purchased a new car --1991 mk2 astra 2.0 gte 16v.
went out today for a spin and I found on hard acceleration the car pulled to the left.
the previous owner who I know very well has lowered this car and put a 5 stub hub conversion from a cavalier v6 onit
he did state when I viewed it that it did this and that I would need to replace the shocks to more suitable ones to help this --can anyone advize me on this please as I'm a bit of a novice when mechanics are involved.
as I said the chap I bought it off has done stacks of work onit and ive known him a long time and hes a mot tester so I trust that the work has been done correctly.
any help or info would be great also can someone advize me how to upload pics onto your forum and I will post some on for your viewing.
many thanks
paul

Yeah could just be down to torque steer, when you put a lot of power through the front wheels it's inevitable

must admit the car is pretty rapid off the mark
is there anyway this can be rectified.
new shocks/bushes etc etc ?
cheers

Are the wheels much different in size and offset to standard ones? Sticky outy wheels do tend to exaggerate torque steer.
I might be wrong but I wouldn't have thought the dampers would be the cause of the problem, more likely worn bushes or a knackered ball joint?
Then again, the misses always says I'm wrong (something to do with being a bloke apparently) so it probably is the dampers after all!

A propper 4 wheel alignment might help a bit and Getting the suspension set up. but its allways going to be there its just one of those things with powerfull fwd cars.

Torque steer. Any wrong wheel drive car with unequal length driveshafts and a bit if power will do it. Our lupo is all over the place if you gun it. It's exacerbated by sloppy wishbone bushes and excessive lowering though (shaft being at an angle rather than flat) to be honest I'd just get used to it, if you want power in a fwd, it'll happen.

That's normal torque steer for one of those.

Possibly torque steer (many cars did not have equal length driveshafts then).
However, I would probably get the tracking at a minimum looked at in addition to the possibility of soft wishbone bushes.

My Golf does it. It's torque steer. I'd still check all the bushes and balljoints, replace any which are knackered or look dodgy then get the tracking/camber/caster sorted. If it's been lowered, definately get the camber sorted. Getting the Camber and tracking sorted on mine was some of the best money I've spent on it. Some of the ropiest cars I've seen were driven by a mechanic  |

Its prob not torque steer! Mk2 astras especially the 16v gte suffer from problems with the bulkhead around where the steering rack mounts to it. This causes the problem you are sugesting. Also if the wishbones have been poly bushed this can wear the pivot bolt mounting point as the bush sleeves grind into the chassis causing the wisbone to move about. Needs investigating properly before anything breaks. Having owned 6 gte's in the past i can almost gaurantee its not torque steer!

Torque steer should be very little really as the 16v has equal length driveshafts not a big issue on mine slight pull both ways at times but nothing scary.

is there anyway this can be rectified. Turn the steering wheel clockwise a corresponding amount whenever it happens. *
*unhelpful, but slightly funny. |

I'd agree it's unlikely to be torque steer. Or to be precise, it probably is, but it's unlikely to be torque steer you just have to live with, it's more than likely something warn or damaged exaggerating the effect. Check anything that may allow unwanted wheel movement. Bearings, bushes and joints being the main things. Torque steer will pretty much always be there, and it's very hard to quantify what's acceptable over the internet, but it should't be something that makes the car hard to drive. Annoying maybe, but not difficult to control.

Had a Mk6 escort in today doing the same, N/S ball joint was borked and the tracking was out (checked after the B/J was replaced), the problem just acentuated the natural torque steer.

my mini has the same engine and box and doesn't torque steer so it must the suspension geometry (or lack of)

Check everything but you'll probably find that it's all ok. Any front wheel drive car with the box on the left will torque steer to the left.
I wouldn't worry about to much because you're not exactly going to launch it on the regular are you?
If you are then start looking for clutch box shafts arms ball joints etc etc. coz it won't last long if you take liberties with it.
Me personally I have never been a fan of launching off the line as it only ruins everything. I am more of a rolling start man.
These is just something I like about going from 30-100 without leaving 3rd haha

I'm not sure. Whilst you can feel a little torque steer, the Lupo Sport I drove was as straight as a die (that was admittedly with new wishbone bushes (it failed miserably at the MOT). Even my Mondeo V6 doesn't pull hard to the left (it does have an intermediate shaft and then the driveshaft for the RHS mind you, but again there is only so much they can do  . I'll go with poor alignment . |
