what vacuum lines?? the breather tubes for the axles? I did do a bunch of water crossings earlier this year...

The vacuum lines that are used for the stock F series hubs, make sure they capped or removed and sealed up to prevent water from entering.

^^^ tyvm, definitely something I didn’t notice when I was installing these 3 years ago.

OK I'm going show my 4X4 "ignorance".
I have a 2003 SMB 7.3 4X4 quigley front end.
I learned the hard way about the hubs when I lost one in Colorado.
I had no idea the bold pattern was not the stock ford (F350 4X4 front end) bolt pattern.
I hear all this chat about people changing front ends (hubs).
Question(s):
1) why are the changing from quigley? (or any other conversion)
2) the Spyntec hubs look really good......what is the bolt pattern? What is their advantage?
3) if the front hubs have different bolt patterns then both front and back hubs need to be changed out and new rims ?
4) are the bearings that fit the quigley hub to the axel the stock bearing for the F350 4X4 front end used to build my quigley front end?
I was very up-set when I found out the quigley is the only option when they need to be replaced.
I'm very confused about this changing out of hubs.
Is it something I should be looking at?
I appreciate any help in understanding why..........
I have 270,000 on my front end and I have changed out hubs 2 times.
I now carry 2 extra hubs with me.

The van bolt pattern is 8 x 6.5" since the beginning of time......at least since 1992-2014....the modern F series truck bolt pattern is 8 x 170mm..slightly larger.


Many 4wd conversions have 8x170mm lug pattern since they use F series axles. The stock van rear axle gets converted from 8 x 6.5" to 8 x 170mm using wheel spacers...but some conversions still have the stock 8 x 6.5" all around.


Wheel spacers are an easy way to convert from one to the other on the rear axle, and wheel spacers are available that just space the wheels out but keep the same lug bolt pattern.

Thank you....I'm still confused with my quigley conversion.
Trying to understand the why's.
When I lost my right front hub (in CO) I pulled in a shop. The mechanic was 4X4 experienced.
He saw the issue, internal bearing disintegrated.
No problem he had a 2001 F350 hub. We installed the hub and went to install the rim ooop's would not fit. He called quigley and they told him that they remachine the stock hub with larger/heavy duty bolts which changes the bolt pattern. It sounded like they change the front 4X4 hubs to match the factory bolt pattern on E 350 vans. Is that what they have done? Is the stock van bolt pattern different that the stock F350 4X4 bolt pattern?
If that's the case then I understand their thinking as the bolts on the van are more heavy duty.
I now carry 2 quigley hubs to avoid a repeat of the CO incident.
We solved the problem by installing the stock hub he had and I bought a stock rim and we switched tires and I was on my way.
It was a very frustrating experience but it also reinforced my faith in my fellow man.

Yes, Quigley machined the 99-04 style 8 on 170mm unit bearings & rotors to make them 8 on 6.5 (stock E series bolt pattern) & avoid changing the wheels. I guess it saved $$ but has to be a headache to deal with now!

I was very up-set when I found out the quigley is the only option when they need to be replaced.

1) I changed so that if I ever have a hub failure I can get a replacement at any parts store for a third of the price of the custom setup from quigley.

2) no personal experience, but if chris is recommending them I assume they are one of if not thee most indestructible setups available. I’ve never seen him recommend junk nor have I heard of any of his conversions failing in any way.

3) not sure when quigley started leaving the front hubs 8x170 and just adding the rear adapter but they definitely didn’t on my 03. I had their custom hubs and a stock semi float rear axle.

4) yes quigley modifies a stock 8x170 f350 hub to 8x165 along with a brake rotor for each front corner so they match the rear stock axle. when you buy one of their converted hubs your getting whatever brand they buy with the holes drilled out and larger shanked lug studs installed.

sounds to me your 03 is just like mine was. if this still isn’t clear to ya, I’d be glad to elaborate further on the phone, just pm me your phone number and a good time to call. it is a very convoluted thing to explain with a keyboard.

Mine is this way - stock 8X170 front with rear adapters. Quigley build date is March 2007.

^^^ imho, they should have done it that way sooner than they did. just seems to me the better way to do things. makes swapping to a different rear axle much more cost effective.

maybe they started doing it that way when they started using the 05+ axles??
