Well yes, there will always be a noticeable drift (towards left or right) after 1 year of Pakistani roads. and after alignment that vanishes. Same for wheel balancing, expect there will be some bouncing (translated to vibrations ) while driving the car is removed also the car "feels" somewhat "tighter" and more responsive after adjustment.
i originally thought i had a barring problem in the front Right wheel . The mechanic who checked said "it appears to be a very slight barring sound coming from the right wheel but it can also be balancing/alignment issue as well no need to worry yet check again after winter but only after alignment/balancing and only if the sound increases after winter "
That was the mechanic (a relatives' friend working at Railway Workshop-the vehicle one not the Train one )
The balancing guy said after balancing there is nothing wrong with your barring <-----is this spelling right
Also the Balancing Guy worked for another relative's friend so he may be biased
