Anybody do their own 4X4 van conversion????

Hello all, been lurking here for awhile and this is my first post! This summer while on a trip out west from Florida, we spotted a lifted SMB and was really blown away with the concept. Our family has been driving minivans since the early 90's and currently have a 8 passenger Toyota Sienna. I never really considered a full size van as an option for our family, but now as family has grown to include 7 grandchildren....more seating capacity could be utilized.

The search begins.... I began reading everything I could find regarding 4X4 van conversions and realized that I wanted not only a 12-15 passenger van, but also the 7.3 motor. Starting with my local craigslist, Ebay, autotrader and any other auto sale website, I quickly realized that what I was seeking wasn't going to be easy to find. By using a craigslist search engine called dailylister, I started searching the entire US. Experimenting with different keywords, methodically scanning each ad for the words diesel, 7.3 or powerstroke, and then it happened!

A 2001 E350 15 passenger with.....a 7.3!!! It was priced to sell, but it was in New Jersey! The van had been used be a limousine company since new, but had 280K on it. The company had a team of mechanics on staff and complete service history, so I was ok with the miles. Afraid that it would get sold out from under me, I reluctantly sent a Wal-mart money transfer deposit to the seller and began planning a trip to New Jersey. By the weekend I had secured plane tickets for myself, my wife and 3 grandsons to fly to New Jersey to pick up the van. If buying a van sight unseen wasn't bad enough the only flight I could get put us in New Jersey at 11PM! The seller picked us up at the airport and took us to the limo company (what are we in for?). Pulling into the limo company lot at 11:30PM we were surprised to see a busy place, people washing and cleaning cars and cars coming and going. The van...needless to say it was easy to spot in a sea of limo's...it looked huge! After a quick inspection and drive around the block...we paid the seller and drove away to find a hotel for the night (full tank of diesel included!). IMG_1746.JPG


We spent the next day sightseeing in NYC....try driving a beast like this through the streets of Chinatown, not fun! The van drove great on the way back to Florida, loved the rumble of the 7.3 and the 18-20mpg avg!!!! My wife even drove it and didn't seem to mind (needs new padding in the driver seat though!). We made it home with no issues!!!

Now that I had the van, what's next? I spent hours reading everything I could find about 4X4 van conversions and came to one conclusion...you'd be hard pressed to not see the name Ujoint offroad, once or twice:Wow1:! Even though there were other companies out there doing 4X4 conversions, it looked as if Chris was the only one offering a DIY kit. I began to email questions to Chris and to my surprise he promptly answered them!! There something to be said for good "old fashioned" customer service in the digital age! Of course everything I had read about Chris and Ujoint offroad was nothing but positive! I definitely admire the passion he has for what he does and respect the void he has filled in the 4X4 van conversion world.

So, as far as I can tell...I have three options...1. Take the van to a company that does conversions 2. Install the Ujoint kit 3. Fab up my own parts and do all work myself. Well, considering the number of miles my van has I can rule out the type of investment a conversion company would cost. So that leaves me with the Ujoint kit or custom built parts. The Ujoint kit and Chris's videos would make the conversion process a breeze and the price isn't really all that bad. On the other hand I have done a 4X4 conversion before, although it was a 1993 Isuzu Trooper converted to a Dana 44 front axle and custom linked suspension, coils and 38" tires, and not a 7,000 pound van. After looking at the different configurations offered by conversion companies I really like the Ujoint set-up and anything I built would more than likely resemble what Chris has put together (what do they say is the sincerest form of flattery:D!). Has anybody here done their own conversion before and if so what roadblocks did you encounter? All in all it seems much simpler than the Trooper I did with my son.

Anyway I will be posting my progress here as I have been truly inspired by many on here and there own projects!! My acquisitions to date are a NV271 transfer case from a 2002 F250, Dana 60 3.73 from a 2002 F350, 10.5 sterling 3.73 2008 F350, and a set of 17" wheels with 33" tires.

We have similar backgrounds.... I have previous experience in the 4x4 world from when I built my SAS explorer, on coils. I wanted something bigger this time around, that my son and I could explore in, AND camp out of for a weekend. So..... I came up with the Lunchbox Build... A fullsize chevy shorty van on 1-tons and 35's. Now, mine's a chevy, so it's different in that it doesn't have a full-frame (it's a unibody) and I'm using leaf springs. But I'm still doing it all 100% by myself, and it's a "backyard" build. If you are comfy with your fab skills, and by the looks of the trooper, you are.... then DO IT! There's nothing more rewarding than building something yourself, for you and your family to enjoy...

Lunchbox, thanks for the words of encouragement and sharing your build pics....it looks like your having a good time with your van project! Keep us posted on the progress.

Maybe I can conquer my fear of automatic transmissions and tear into my 4R100 for the tailshaft swap! I have found a tranny shop that will convert my tranny for $450 so I may be able to stay skeerd for now! I've spent my whole life in the welding and fabrication business (Industrial) and enjoy creating "one of a kinds". My off road vehicle experience is somewhat lacking and the Trooper project was actually the brainchild of my son who designed all the parts and pieces and convinced me to torch off all the IFS stuff and weld up all his parts. He was a sharp kid and wish he was still here to help me with this van. I'm actually drawing my motivation for this project from his memory and for his two littleboys.

Does that price for the tail shaft swap include parts? If so not bad, if it doesn't keep in mind the swap on a 4R/5R 100 is about as easy as it gets. Pull off the tail shaft adapter, remove output shaft & insert new one. Bolt on new 4x4 tail shaft adapter and do the happy dance. Those trannies disassemble from the rear. You don't even have to unbolt from the engine. My E4OD unfortunately disassembles from the front and the output shaft is the last thing to come out. Unhappy dance. But I was rebuilding the tranny anyway so...

Transmissions and ring and pinions are the two things that I don't feel comfortable doing myself. Luckily, I know people that do this stuff for a living, and I can usually talk them into doing it on the side for cash. Although I did all the *****-work, my buddy did the final assembly on my 700r4, well worth the $300 I paid him. I just dropped off my dana 60 to another buddy to set up the ring and pinion. When he's only going to charge me $100, it's hard to resist. Again, I did all the tear-down and clean-up, so it was ready for final assembly when I took it to him.

I was assuming the $450 included the parts.... Wow, I didn't know the swap could be done with the tranny in the van...if that's the case, I'll probably do the swap myself!

I parked the van next to the Trooper today and was surprised at how tall the van already is in stock form!

No need to reinvent the wheel, the money you "might" save doing it on your own will be far out weighed in convenience and the fact that either UJOINT or AGILE will be their to answer questions WHEN the arise! Just my 2 Lincolns

I'm not a person who has a ton of money laying around. When I want something cool, I usually have to build it myself. I bet I build my ENTIRE van for what the 4x4 conversion would cost from one of those two companies. Not to say that they wouldn't do a great job, because I'm sure they build quality vehicles. If somebody has the know-how, and the tools, I don't know why you would have somebody else do it? I get a lot of personal satisfaction knowing that I built something with my own two hands....

A 4R100 and an E4OD are essentially the same and both require disassemble to exchange the output shafts. The 5R100 Torqshift is just a bolt on deal.

You will have to pull the transmission. $450 should cover the parts in your situation.

I built my own 4x4 conversion for myself and I believe Chris did to (I am not sure) and turned it into a business.

Do your own.

If building suspension systems is someone's passion and hobby that's great, it can be a lot fun. From my observations over the years wheeling, a lot of people can source parts from scratch, stick an axle under the front of a vehicle and make the front tires turn. Less people can do it safely, have it perform really well and last for several years without premature part failure.

Not all vendors supply a quality product either. But what you get from the good vendor supplied parts or conversions is all of time they spent optimizing their design so that the final product is as good as or better than a factory OEM system.

I've done a couple front axle swaps on Toyota pickups and for my time and money, I prefer to use as many tried and true vendor supplied parts as possible. On my 4runner, I pulled my junkyard built front leaf packs out 3 times changing spring configurations until it rode how I wanted it to. Been there done that, it was fun at the time but now I'd rather pay someone for their time and have the design and testing done so I only have to bolt it in once.
