Post subject:  Steering problems on TX1
I've been having steering problems recently and the 2 garages I went to haven't been able to figure out what is wrong :roll:

Basically the steering wheel is very sensitive, its like I'm driving on ICE. When at speed, the taxi drifts slightly side to side, poor road holding.

Have had tire tracking done, tire pressure is normal, steering damper changed and had the steering box changed as the old one was leaking.

The over sensitive steering problem didn't disappear and I'm at a loss as to what to do to fix the problem.

1.. what make of tyres do you have and what pressure is in them.
2... if you are sitting in your taxi.. with the engine running... can you place one finger on the steering wheel and turn the stirring to its full extent either way.
3.. forget about the steering damper..
4.. you say you have had your tracking .. tracked... was it by a garage that knows how to track a T X one.... and what did they set it to...
5.. Do you have any problems with your rear springs... is the vehicles lifting at the front when you have passengers in...

1) Kingpin remould tires. I've always used them. Pressure 36 for front and 38 for back. Tried 40 for back but made problem worse

2) Yes

3) Ok.

4) Yes, they track taxi's too, many taxi drivers go there and it isn't a new place. Don't know what they tracked it to.

5) No, taxi doesn't lift at front with passengers in.

Thanks.

1... you can get a fault with the steering box... in that it becomes super sensitive.... I would suggest you compare it with another vehicle... just try turning the wheel when it is stationary.
2... you can also get a weird sensation through your Steering when it is incorrectly tracked you tend to notice it more when you are going round a traffic island ... it gives the impression that you have to correct your steering.

1) I was able to turn the steering with no problems on another stationary TX1 with engine running with working steering. It was as sensitive as mine.

2) I have to correct my steering when I am driving on a straight road or motorways. When it is windy outside, the problem is worse. I don't have problems going around corners or traffic islands.

same as mine
i replaced everything at the front becouse the vehicle was feecked when i got it,when i finished the rebuild it felt like the wheels were coming off.
it felt like wheel bearing but i knew it wasnt as id replaced them.
adjusting the tracjking sorted it out mostly.
i did mine with some string,but its still not quite right feels very sensitive and light on the road,like yours.
just for reference i replaced everything at the front end both plates,springs,shocky's,bushes,disks,wheel bearings,calipers, and balljoints,so all brand new and mine feels like yours so id say its iether the tracking,or some problem in the steering box.

by the manual this is the procedure

STEERING SETTING
PROCEDURE –
FAIRWAY DRIVER AND
SUBSEQUENT MODELS
INC TX1
Please follow steps 1-5 in sequence, this
will ensure correct steering setting.
Step 1 Set Centre Bar
1a. Measure centres, steering box output
shaft to idler box shaft (see fig 1). Add
58mm to this dimension.
1b Set the length of the centre rod, centre
to centre of the ball joints, to the
dimension determined above, and
tighten locknuts.
Note: Do not set tracking on this rod.
Step 2 Set L/H Turning
Circle
2a Set the vehicle on steering pads,
footbrake held on.
2b Set left front wheel straight ahead using
a long straight edge from the rear wheel
and zero the steering pad.
2c Apply full left hand lock at the steering
wheel and adjust left hand tracking rod
until a reading of 58.5 degrees is
obtained on the steering pad.
2d Tighten locknuts.
Step 3 Adjust Tracking
3a Adjust toe-in to 1,5mm (+1,0mm/
-0,0mm) using right hand track rod
only.
Step 4 Set R/H Turning
Circle
4a Set vehicle on steering pads, footbrake
held on.
4b Set R/H front wheel straight ahead
using a long straight edge to the rear
wheel and zero the steering pad.
4c Apply full right lock at the steering
wheel and check the right wheel
backlock angle is 57.5 degrees. If not
go on to step 5.
Step 5 Steering Box
Adjustment
5a Remove the protective cover from the
adusting nut, located underneath the
vehicle at the front of the steering box.
5b Slacken of the locknut, and adjust the
backlock angle to obtain 57.5 degrees.
Turning the adjuster clockwise = reduce
backlock angle. (This will increase the
turning circle).
Turning the adjuster anticlockwise =
increase backlock angle. (This will
decrease the turning circle).
5c Once a backlock angle of 57.5 degrees
is achieved secure the locknut and
replace the protective cover.
Note: Adjusting the steering box affects the
right hand lock only.
