What car My fronteras doing this 9/10 it would be fine then it will go tight loose tight loose and then be find again after a bit
Check all your ujs im the steering column – any bevel boxes make sure they are all well greased with no play. Get someone to turn/rock the wheel while you hold the ujs- looking for no play. All ball joints and tres are in good fettle ?
Garage are changng the rack on my car after changing the power steering belt didnt alleviate the issue for me ( id changed the inner and outer tie rods , upper and lower ball joints and wheel bearings +wheels and tires – as all were pretty shot)- they seem to think the pumps good and i tend to agree having had the gauge on the outlets.
My partner also used to do it – badly worn front near side tire ( at an angle almost) and really badly adjusted tracking was the cause on that – that is to say i got new tires and tracking done and have never had the issue again but it was consisantly there the tit loose tight loose pulsing feeling
