help please with my symptoms

[SVXBart]

1992 lsl 106 k(new front rotors/pads/tires,all wheels rebalanced,done aligment)
i'm still gettig:
1) above 20 mph stering wheel start to studher very slightly,aroud 45-60 mph when taking turn shking even more,and when breaking,and i'm not sure if i'm feeling it right butit also depends if accelerating accelerating or leting go gas pedal
2) when relasing break pedal after complet stop and when pushing it to complet stop can hear some creak from front wheels

As for the steering wheel check to see if the power steering fluid level is set correctly.

Some people have found that the o-ring between the power steering pump the the reservoir has completely deteriorated and causes issues similar to this. Simply replacing this o-ring resolves this issue.

As for the creaking noise try to narrow down exactly where the noise is coming from. It's possibly the front sway bar bushings.

Your diagnosis if accurate, indicates that the vibration is torque related and does not effectively indicate a steering fault, as it would appear it is present in a straight line. Could well be a CV joint, bearing, or a suspension component loose/worn and moving under wheel torque. Careful inspection, while rocking each front wheel off the ground, may show up something.

Do not rule out a faulty tyre/tire as being a possible. I know from annoying experience, that effects can be weird.

stering fluid lewel is ok, i forgot to ad that i have brand new ps pump instaled,
ill prooably go back to my dealer - they ofered me free break inspection-and i still have 2 old tires on back so ill have them checked.
is it posible that brand new rotors can be wraped?
another related thing: she is pulling right when driving and when breaking
any ideas about noisy creaking breaks?
thank you all

Perhaps one of your calipers is dragging.

So, are you saying that you only buy two new tires at a time? if so, you are in for some BIG trouble tranny wise.

I learned the hard way, lets hope you dont have to.

Also, simply having over torqued lug nuts can cause that shudder.

yes i got only 2 new(bf godrich g-force sport)and instaled them with new rotors and pads on the front
old two tires that were up front are on the back now(together with old rotors and pads- i'd love to have it done to but i need to save around 1800$for all the leaks she has ) but they still have like 80%tread left(hankang ex 500 )
can you explain thr tranny problem that is interesting
about over torqud lug nuts i will have that checked soon cose now i have tourqe wrench that i didnt when i was replacing front breaks
and i had all those sympthms before doing front breaks and tires
thank you
im waiting for your replay about tranny

The problem with the transmission, is that the rear wheels with the smaller dia tyres, will rotate faster than the bigger front wheels. This difference in rotational speed, has to be accounted for by the transfer clutch slipping. Too much slipping = too much wear.

Though if the rear tyres are only 20% worn, I would not worry too much about it.

If the tyres are a different brand, as it would appear from your post, this could make the situation worse or better as all brands are not exactly true to specifications. N.B. You must check the effective rolling diameter of the tyres front and rear.

With tyres at your normal operating pressure, measure from the centre of the wheel to flat ground and compare. If you find it hard to establish an exact centre point you can work off a wheel nut in an exactly the same position for each wheel. Vertical would be easy.

You are not trying to measure actual diameter and are simply comparing front and rear. You can mark a stick rather than use a measure if you like. Hopefully there will be only a small discrepancy.
