Considering everything is new in front, check your tire pressures first. That’s an easy place to overlook the obvious. If that doesn’t solve anything, put some time into inspecting your rear suspension. If you’re still content it’s in the front end, then it’s time to shake the front wheel bearings for play and, likewise, check the joints in the intermediate and lower steering shafts for play. At least one Wheel bearing is probably due given the mileage. Prove them faulty before you just go replacing either of them. But, if you find a problem in a steering shaft or its joint, it’s a one in a million fault.
