would check your lower arm bushes/balljoints

if its wandering its more likely the track control arm (wishbone) bushes worn

If all suspension & steering attachments are OK,& not unduly worn, check tyre pressures & wheels (buckling due to kerbing) or, more likely, front wheel alignment, i e toe-in or toe-out, according to spec. Tyres will show abnormal wear if alignment is out. Correct alignment may have been disturbed if you have changed the rack & pinion & not re-aligned the steering.
