'08 450h pulling to the left...

[madfish]

I'm hoping someone may be able to help...

My car is constantly pulling slightly to the left, I'm having to steer to the right to keep it straight.

I had the tracking adjusted and getting green across the board. All 4 tyres are good and pressures are as they should be 36/38.

Suspension has been replaced with known good OEM parts and drives great with noticeable difference between normal and sport.

No knocks or bangs, all bushes and ball joints seem ok

None of the wheels seem hotter than the others after a good drive and can't hear of feel any play in the wheel bearings...

Ive read a few posts about zero point calibration and resetting steering ECU?? How is this done? Before the tracking the steering wheel was off center quite a good bit.

Also, and I don't know if related, anything above 60mph the car seems to wander, requiring constant correction to the steering... 

And finally, every now and then, mainly after driving on motorway the steering wheel/shaft seems to stick a little for a second taking away that smooth Lexus experience...

Im wondering if all the above are related somehow but so far I'm baffled!

Ay help much appreciated :)

Try increasing the front tyre pressures by 2 psi..it worked when I had a similar problem  in my Mazda CX7

Thanks for the suggestion but I actually dropped the pressure from 40 in the fronts (previous owner) to 36... Fault was there at both pressures.

Well to provide an update on this if anyone is interested...

 

Both front lower rear wishbone bushes have completely perished and the NS tyre has some bad wear from the previous bad allignment. Garage reckons this may be the cause of the pull to the left...

 

Also to rub salt in the wound both rear shocks are leaking.

 

Big bills coming :(

New bushes on way over from Japan...

 

Plus have these to fit ...

Ha, had the exact same issue. Was only steering 1-2' right to correct but was starting to annoy me 🙂

I think my mistake was letting Halfords do a wheel alignment after getting my tyres changed... that garage didn't seem like the most competent in the world to me!.

Halfrauds are excellent at doing what they do well, well.

 

I just haven't discovered what that 'thing' is yet.
