i've pruchased the new bearing assy for my wife's 328is. my only concern is getting the new assy on. i know the job requires a puller to get the old bearing off (and a HUGE 45 mm socket with a 3/4" breaker bar!), but will i need to have the new bearing assy pressed on to the steering stud? will the HUGE 45 mm nut effectively seat the new bearing on the axle? thx, bob in houston.
