u can check your inner axles by checking the looseness in them...park the car on some deck and try to move it forward / reverse keeping e-brake applied...the person under it can monitor the play in inner axles....i guess this is the 'desi totka' to verify play in inner axles...lets wait for the experts for final verdict.
to rule out the alignment issue...give Watto motors a visit on PECO road lahore...get all wheels balanced and then aligned...
