I would have kept the 9 inch and do a disc brake conversion with a posi unit.flip the rear on top the leafs and call it good.you do very clean work by the way.

[@kevind3185]

Glenn Grider bolt pattern wouldn't be the same as the front then.

[@jamesbascombe6869]

I agree I have a 9' rear in mine as well. And I am keeping it. Besides the 9" is stronger. Mine has the nodular center chunk as well as 3:55 and a Detroit locker.

[@REVNUMANEWBERN]

EXCELLENT idea of layout with the notching out of spring pads.

[@jimgeelen658]

hey Texas know how.. I've followed all the videos on this truck, I am doing my 72 F100 right along with you. I purchased a 2000 explorer rear end with disc brakes and 3:55 gear ratio from my local auto recyclers, the only problem I have now is what size rims and offset I need. I was hoping to run police interceptor wheels but the offset wont allow it. what size rim/tire and offset are you using for the rear.. Thanks from Jim in Canada

[@Texasknowhow]

Jim Geelen - Hey Jim, thanks for following along. For now I purchased 2” adaptors (I’ll discuss in a soon to come episode). They are good ones and will allow normal offset wheels to mount up and clear. Long term I’m purchasing shallow back spaced wheels to keep them outward. I’ll post up the details in my comments section on the next vid. C

[@jimgeelen2354]

i would really rather not run spacers, here in Canada you cannot certify a vehicle with wheel spacers. So i may look into putting the original rear end back in and purchase an axle flip kit, i've seen them on here, you get the same stance but obviously lose disc brake, wheel bolt pattern, posi, etc.. Custom rims are expensive. Thanks Clay take care!

[@danhammerl]

Can the stock explorer shock mounts still be used with the stock f100 frame shock mounts?

[@Texasknowhow]

Yes, the shocks lay down a little but many folks run them this way.

[@RIPbiker13]

I got the rear from the police car I got my front from. 3.55L with disks. It doesn't have perches because it was a 4-link in the car. I'll habe to get new perches, but when I do, speaking won't be an issue and I'll set the pinion angle without shims. Kinda wished I could find an explorer so I didn't have to deal with it but people want a fortune for those with the disks around here.

[@falcon6995]

The Explorer rear ends have a 2 inch+ pinion offset.

[@RIPbiker13]

@@falcon6995 The offset is typical. I addressed the pinion angle when I installed the new drive shaft. If you look down the center of the vehicle, you'd notice the engine and trans are offset also, so the offset in the rear is, well offset.

[@NextLoadJunkRemoval]

awesome info again thanks alot

[@darrenbridges3152]

Dude, your videos have been more helpful than 90% of the stuff posted on you tube. I'm doing the same thing to my '69 ( well, what I'm able to,do.i am disabled because of my back) but being able to show people your ideas on making the jig for drilling the rear spring mounts etc... has made this MUCH easier than trying to explain it. What part of Texas are you from ? I'm about 80 miles east of Dallas. I would love to compare trucks when they are driving ( they are never finished !) thanks again and keep up the good work ! Give a Texas country boy a screwdriver,a crescent wrench and some balding wire and duct tape and we could have built the pyramids!!!

[@Texasknowhow]

Darren Bridges - Thanks for the compliments Darren, really appreciate that. My videos have come along, getting better and better as I learn. Post processing is what makes a difference. That and multiple camera angles. I'm a visual learner and a big believer in videos for understanding something. Sorry to hear about your back; get a buddy or family member to help with the heavy lifting for sure. I'm from Greenville , I'm sure you've been through there on I30. I live in Virginia at this time due to my day job. Best of luck with your truck my friend. C

[@jameslaperriere8152]

I have a 19 80 square body Seton I’m trying to figure out how to center the rear end it has air ride suspension how can I figure out where is properly where is it properly centered at

[@Texasknowhow]

I haven’t modified a C10 but pretty sure your 1980 still uses Coil springs on the rear. I’ve own two C10s in the past. With that setup, you need to clamp the big trailing arms to the rearend housing at the same distance as they were on the original axle housing. I.e. find a place to measure from that is identical no matter which side you are on.

[@christopherhurlocker9417]

what would the difference be if you put the 8.8 under the leaf springs instead of on top of them would the angle be correct

[@Texasknowhow]

It would change the angle but only slightly. Also it would lift the rearend up quite a bit and I wan the low look. They make shims that go under each leaf spring pack that correct the angle; I plan to use them if needed. Clay

[@kyleiankade]

Nice and very informative videos. Question- when you swapped your rear, did you shocks mount up to the stock location or did you weld so,e in place.

[@Texasknowhow]

Thanks for the comment and Question Vincent. I was able to use the U-bolt plates from the donor Explorer for the axle side mount and used the factory location on the frame rail for the other end.

[@kyleiankade]

@@Texasknowhow Thanks, that's what i needed.

[@kevind3185]

There is no way a Northern Truck would come apart like that. We got to use a cutting torch on a five-year-old truck. You literally tapped the bolts out from the front spring mounts. The little round bushing inside the rubber bushing would literally seize to the bolt. You guys got it good down there in those dry States

[@Texasknowhow]

Kevin D - Amen Brother- I don’t take this for granted. Hot in the summer, but pretty much perfect for 9 months of the year.

[@keithw372]

you should take some copper tubing the same sizeas the new hole, put it in the new hole so weld doesnt blead over and some flat copper from underneath and weld the older hole up.. use the copper as a backing for the weld

[@Texasknowhow]

Good idea Keith!

[@mikepine5122]

How do you deal with the off center 9inch with this 8.8 swap from the motor perch

[@mikepine5122]

Nevermind i see you swap the front as well

[@JohnAnderson-vc6po]

Clay what size hole bit you used to cut ??

[@JohnAnderson-vc6po]

And what size shim to get The pinion level?

[@Texasknowhow]

@@JohnAnderson-vc6po - I’m trying to remember, but I think it was a 5/8” hole saw bit. I remember trying to match the existing hole and just move over 3/8”. After its cut it’s like a snow man shape, then I carefully laid some weld in there to close the leftover old hole.

[@Texasknowhow]

@@JohnAnderson-vc6po - I didn’t shim my pinion angle but I may have to. Need to get my Engine and Trans all mounted up first and check that output angle first. Then I’ll match it - equal and opposite.

I can't remember if you said what year the Explorer rear axle was? Do you remember? I need one for a 1958 F100 Vic swap. Thanks!

[@Texasknowhow]

[@ReverseGear]

Texasknowhow Thanks. I know where 10 are. If I'm lucky. A 3:55 limited slip will be there. And then I can just rebuild it as is.

[@Texasknowhow]

Reverse Gear mine is a 3.73 but they may have come with some 3.55 gear sets. Those would be better for highway mileage. BTW, it will have 3L73 where the “.” Is an “L” for the Limited Slip diffs.

[@c.franklinkielich9443]

The Ford 9" is arguably the greatest rearend ever made. I really don't know why you would swap in an inferior rearend in your project. The stock 9" is MUCH stronger than the Explorer model and you can get parts to make it handle just about any horsepower. You can have the axles drilled to whatever bolt pattern you want and aftermarket disk brake kits and gear ratios are available and easy to find. There is a reason every NASCAR race car is equipped with one.

[@Texasknowhow]

C. Franklin Kielich - I agree with everything you say here. It was just a cost decision. $100.00 and I got the right bolt pattern, limited Slip diff, the gear ratio I wanted, disc brakes and a sway bar. What would all that cost to get done to my old 9”? I kept the 9” I’m not crazy! Haha

[@juancervantes561]

I have a78 F-150 could you tell me what used rear differential with disc brakes brakes will fit my truck

[@Texasknowhow]

Hi Juan, I would post this question on one of the Ford Websites like www.Fordification.com. I don't want to tell you the wrong ones. I do believe that are many that will fit though.

[@Fordf-td6wq]

wouldnt the driveshaft bind up do to the offset of the engine?

[@Texasknowhow]

Ford 67f100 - Technically it can offset to the side or up and down. A spinning driveshaft doesn’t really know left, right or up or down. However, the pinion angle of the rearend needs to match that of the transmission output shaft AND the pinion and transmission need to be relatively parallel. I.e. an imaginary line out of the pinion and another line out of the trans output should be parallel. Folks use this rearend all the time not centered. This is a great question.

[@Fordf-td6wq]

@@Texasknowhow thank you so much you dont know how much of a pain it was to get an answer anywhere for this

[@jr7392]

Yeah, appreciate this info as well. Kid and I are doing a 70 Mustang and was wondering if we'd have to narrow the axle to get the right track for wheels. Will definitely have to relocate perches but nice to know we can offset. Thanks!

[@falcon6995]

@@jr7392 The rear end on your Mustang is narrower than a truck rear end. The 67-70 mustang's had 59.25 inch rear ends measured from wheel mounting surface.

What did you do for shocks

[@Texasknowhow]

This is embarrassing, but it still is a project in the works after all these years and I've not put shocks on it yet. There are a few of these video series out there where the guys did the Explorer Rearend so you may want to look for those videos for ideas. Thanks for the question and for watching the video! Take Care, Clay

[@joemarshall712]

I'm curious as to why you changed from a 9 inch to the explorer 8.8. Was it for disc brakes? If so, you could have used the disc brake set up from the crown Vic. I did that mod on my 69 mustang that also has a 9 inch.

[@Texasknowhow]

Joe Marshall - that's a good question. And I've answered it a few times on different videos of this series. In short all the benefits of a 33 year newer rearend. Limited slip, disc brakes, sway bar, leaf spring perches already set up for SUA, has the right bolt pattern to match CV front. The last one is what got me thinking about it in the first place. Also it's more narrow so I can run deep dish wheels. Cost $100 plus a few gaskets, seals and fresh full synthetic oil. Not a bad package.

[@butchjohnson1250]

The 05 Crown Vic front suspension is 67.5" face of hub to hub. My 71 Flareside/Stepside measures 62.5" face of hub to hub. I assume your 67 would be about the same as my 71. What tire wheel size combination are you considering for the front.

[@Texasknowhow]

I think I'm going with 8x18s on the front. The offset will have to be right for it to sit right in the fender. I'll try to find my notes I've taken over the last year of what others have done that looks good.

[@ltsgarage7780]

How long ago did you do this work? I would have 4 linked it. I'm in the process of installing a Jaguar xjs independent front and rear suspension in my F100. I'm pretty much done with the front. I'm not looking forward to the rear end. The Jaguar setup is narrower than the Crown Victoria suspension is. You can put on rims with more offset to them. The front of the crown Vic puts the tires right out next to the fender well. Plus the Jaguar has bigger bearing & brakes. Good luck. Keep working

[@Texasknowhow]

Lee Olaeta - the front of mine is pretty much done. The rear is put together but I want to 4-link it. So it may still happen.

[@ltsgarage7780]

@@Texasknowhow oh God. There is a whole list. I used the 1995 XJS. It has the best rack. If you Google it. They do have a complete list for them. I went with the newer year because I wanted the outboard rear brakes. The inboard look cooler. But I'm old. I don't want to have to pull everything apart to change rear brake disk. The other good part is. It's an old school Chevrolet bolt pattern. There are a lot more wheel selection for Chevrolet than Ford. I've already purchased my wheels. 20x10 rear 18x10 front. I might switch & go to 20x10 in the front 22x10 rear. I notched my front frame 1-1/2 inches to make it sit even lower. Aired out it will sit about 2 inches off the ground. I also welded mine in. The crown Vic is a very easy install. The Jaguar is a bit more work. But it is much narrower from outside of disc to disc. You're not stuck on your wheel choices.

Not sure if I want to burn up 2 semi valuable parts cars to do a F100 build, but would have no problem using one or the other.

[@Texasknowhow]

James Harrison - What year P71? Rear ends are different widths depending on the year. Ie 02 and back have a reared that is a good width for our trucks. 03 -11 the tear ends are really wide. They work, but you are limited on your wheel width options. This is why folks choose the Explorer rears. They are narrower. All these options mentioned get you a matching wheel lug pattern (5-4.5) which matches the Vic front k-member swap. A full frame swap, which is an option, as well will also work with the Vic doner. Tons of info on this. River City on KZbin has done this for example.
