What front end do you have?
My 03 Quigley has an 03 f350 front axle. According to Quigley when I called their replacement rotors are just 03 f350 rotors that they have drilled out to accept the 8x165 bolt pattern. Same with their bearing assemblies. They drill out the 8x170 pattern to accept larger diameter lug studs so that the bearing assemblies match the stock rear end.
When my drivers side went bad I decided I didnít want custom parts like that on my van so if I do have an issue somewhere I donít have lifelines I can use off the shelf parts. So I just replaced both my front hub assemblies with stock f350 assemblies I purchased from rock auto for $179 each. That meant I needed to do something with the rear axle so that the bolt pattern matched. So I replaced my rear axle with one from an 05 f250. I did this to get a full float axle since my van had a semi float. You could also just get wheel adapters for the rear axle, but Iím not a fan of them even though they have a pretty good track record with mang forum members.
Yes I had to buy new wheels, but I wanted new wheels anyway. So I bit the bullet and did all that stuff at once. Other than the new wheels, all items were purchased for around the same price as 2 new Quigley hubs.
