GET THE TRACKING DONE MATE. OR BETTER STILL GET IT 4 WHEEL ALIGNED.WHENEVER A CAR HAS BEEN LOWERED IT SHOULD ALWAYS GET TRACKED UP PROPERLY OTHERWISE IT WILL PULL AND YOUR TYRES WILL WEAR OUT FASTER THAN NORMAL.

[matty101]

i duno wot its like round where u live but most of my local garges wont touch lowered cars, so u might have to shop around abit

[Corsa84]

my local said it would cost me £65 for 4 wheel alignment but they advised me to wait until ive got my alloys on,coz it will be a waste of time doing it with 13inch wheels on then swapping wheels over coz then it will be out again lol.

saying that mine dont pull and mines been dropped 60mm.

They are either lying or stupid. Or both. Alignment is nothing to do with what wheels are fitted. It is refering to Suspension and Steering rack adjustment.

In fact, as Matty pointed out...bigger wheels (with lowering) can mean that lazer alignment gear often doesn't fit, so garages can't be bothered with it. It'll be easier for a garage to do it with the older wheels on and more space. Unless you're lowering it at same time as that obviously does affect it.

Rear 'wheel' alignment is generally a waste of time of rear axled cars IMO, unless it's completley screwed, there isn't not much you can adjust easily short of shimming etc. Really on older cars It's tracking and camber that are the main ones to check. FW Tracking should cost less than £20.

Find a garage that has the older style tracking /camber gauges. (ie the dunlop mirror setup), they don't clamp to wheel so are unaffected by height/wheels.

The best places i've found are garages that deal with track cars...firstly they have the gear so they can do basic tracking/camber checks at track, secondly they tend to actually know what they are talking about...unlike most of the retards you'll find in Kwit poo etc...

Sounds like the EPS (electronic power steering)
car usualy pulls to the left (or sometimes right) and its heavy to turn the opposit way

its one of the most common problems by far with the Corsa EPS
in some cases it can be fixed, other require a replacment steering rack
bit of a guide on how to fix:

Tools Required:
Medium sized Phillips screwdriver, T2.5 Torx bit, flexible driver,
small 2BA or 1/4" ring spanner, 13mm ring spanner.

Turn the Steering wheel to expose the two pop-on screw covers on the
retaining screws for the steering column switch covers, remove the
covers and the two phillips screws underneath. Remove the three
phillips screws underneath the lower steering column switch cover and
remove the cover. Remove the fuse cover and take out the two screws
beneath the fuse box to allow the lower section of the dash to be
pulled away.
On the lower right hand side of the steering column assembly just
inside the dash, there are two torx screws holding the steel cover
plate that protects the torque sensor. Remove both of these using the
flexible driver and T2.5 torx bit. Remove the cover. Before
proceeding, mark the position of sensor body relative to the steering
column body.
If you only need to reset the torque sensor position, you need only
loosen the screws to allow adjustment. If you need to fix the
sticking steering problem then the sensor must be removed. The torque
sensor is retained with two more T2.5 torx screws. The lower
retaining screw can be accessed fairly easily by pulling the lower
right section of the dash away from the metal structure. The upper
one is more difficult and may be slackened using the torx bit in a
small ring spanner.
Next, turn the steering column to gain access to the bolt that
secures the lower steering column universal joint to the rack spigot
that projects up through the floor. Remove the retaining bolt and
swivel the joint away.
If you have a short piece of plastic drain pipe or a cardboard tube,
slide it over the universal joints so that the steering column is
free to turn without jamming on anything (like your hands).

BEFORE TURNING ON THE IGNITION, READ ALL OF THIS BIT!.
When the ignition is turned on and the engine started, the EPS will
drive the steering column depending on reading of the torque sensor.
If you do this now, there is a chance that the wheel will be driven
continously in one direction. The column has a position sensor at the
top behind the steering wheel that will count 30 turns from end to
end before it jams. Check this before proceeding. Then turn the wheel
back to centre (15 turns from one extreme).
Now be ready to turn off the ignition if the next step causes the
wheel to spin rapidly. Turn on the ignition and start the engine. The
steering may spin rapidly, Switch off if it does. Rotate the torque
sensor fractionally and turn on the engine again. Repeat this process
until the steering is still when the engine is running.
Then, give the steering wheel a short tug in one direction and let it
settle, then do the same in the other direction. The wheel may
continue a little or might bounce back a little. If necessary adjust
the torque sensor position until the behaviour is identical in both
directions.
Now switch off, and check the steering centre position by counting
the turns, and reset it in the central position.
Repeat the torque sensor setting procedure to ensure that the
behaviour is identical in both directions. Adjust if necessary. When
you are satisfied that the steering is balanced and neutral turn off
the ignition, and tighten the sensor retaining screws.

Refit the Sensor cover, re-assemble the lower universal joint, refit
the covers and screws and test drive.

hope this helps

THANKS FOR UR REPLYES JUST WANNA SAY IT DONT HAVE EPS AND HAS STANDERD 14INC ALLYS SO U THINK I WILL JUST NEED TRACKING OR TRACKING AND ALINMENT?

[ManicGTI]

Well a good start is Front Wheel Tracking, and possibly camber ('alignment').

Don't bother with the rear, waste of time on a solid rear beam.

Octanes got a good point though, even if you don't have EPS, it's worth having a look over the rack. Loads of things can cuase sketchy steering. It's worth checking over all the bushes and fixings for the suspension and rack while you're there.

I had a 'similar' problem on my last Golf Cabbie, turned out the spot welds had broken on one of my steering rack mounts. So all the suspension setup seemed fine at a standstill, but the rack moved slightly on steering.

40mm lowering on standard wheels should not cause a problem for any half decent garage. If they can't manage with that I suggest they are not worth taking your car to anyway.

Maybe the PAS has gone

I had problem of heavyh steering when turning right, looked at ball the advise and it sounded just like the lubrication issue, i followed the steps to remove torque sensor and put lube down void , when i replaced torque sensor it seemed to refit fine but when i turned steering it was heavy as hell and the eps light is on permanent, i guess i have screwed up the sensor, or could it be something else ? any advice on how to fix, its my daughters corsa b 1.2 16v, 1999. any help would be appreciated

[johnny]

Always start with the simplest solution so have you checked the fuse? Could have shorted on removal or refitment

Next is sensor, get one from a breakers should only cost 5 quid because they won't know what it is

Unfortunately next step is more than likely new rack time
