Thought you Isuzu guys might want to see the trooper we did. It turned out really good. Drives likes a Caddy! I can't wait for the guy to take it to Rubicon.

84 toyota front with Yukon Chromoly shafts and Birfield eliminator, 5.29
Labs Double arm crossover
Rubicon express springs
IFS Toyota rear with 5.29 and Detroit (Used stock Isuzu e-brake cables)
Spring over in rear with factory springs and 2" blocks.
Machined rear flange to accept late model toyota rear CV driveline
Machined front driveline flange to accept Toyota big bolt flanges and 8" slip
Rancho 9000 shocks
35" tires on 8" rims
1.5 WFO wheel spacers up front.

how does the front driveshaft do? any bad vibrations at higher speeds? pics of both driveshafts would be nice

excellent looking rig

The front driveshaft works great. Of course, it is at an extreme angle, but I didn't have to modify the crossmember at all. I put the slip yoke up at the t-case to make it clear. I don't have any pictures because the owner already picked it up.
There was no way that the factory Trooper flange was going to have enough flex. I used the big bolt pattern toyota flanges. They have tall ears on them to allow about 45 degrees of angle. I took about .100 of of the isuzu yoke in order to get rid of the big diameter centering chamfer. Then I machined a smaller one in to fit the smaller diameter toyota center. With the yoke off, I clamped the toyota flange on the isuzu flange and center punched the 4 holes clocking them away from the existing holes.
Due to the fact that Toyota never had a big bolt pattern flange at the axle, I had to drill 4 new holes in that flange too. If you don't have a new crush sleeve, you have to do that one wile the flange is still on the axle.
With the 8" factory style slip, and all new ends and flanges, the driveline was just under $400 to make. Due to the high angle, it has a slight vibration at speeds over 25 miles and hour. However, off-road, it is perfect!

In the rear, I used the CV from a 2001 Tacoma. It had a rear 2 piece driveshaft. I took the whole rear piece in an had it lengthened. It cost about $100. My driveline guy said that the new toyota CV's are great units, and really cheap to rebuild. They also get quite a bit more angle than the old style ones. On the t-case flange, I did the same thing as the front. I had to grind the back of the CV a little bit to clear the nut. I cut the crossmember out of the trooper, and welded in a new tube one for clearance.
If you want me to build you a front driveshaft, I can do it. I just need your flanges. Trevor

wow the truck looks great, you did a great job. you're doing the same set up pretty much i'm doing to mine, yotas front and rear with the 5.29s, ect. what kind of power did the truck have when you were done, enough to pull itself? was it a 4cyl or 6? also how much would you charge for a rear drive shaft? i haven't gotten to that point yet but i need to start thinking about it.

Thanks

Hey T, did you used to work at Foothill Offroad in Auburn ?

Nope! I graduated from Chico State with a Manufacturing Major in 2000. I worked in the Bay Area for a few years as a production manager and plant manager at a Large Foundry. I got tired of the Big Show and started my own! Trevor

wow! that things flexes NICE. great job. that thing is running what i've got on mine, just about the same gear. i was going to install lift blocks but i have heard bad things about axle wrap on the trail. love the steering set-up you guys have. im goin 5.29's lock rites f/r also.

i need some tips though, im hearing some severe vibrations on the highway for the rear shaft, got mine made by a driveline shop, my e-brake cable is also hanging at the moment next to my shaft so dont know if that is causing it. also, how far forward would you say you moved the axle? great work.

Trevor

Even though the rear blocks are small, I think I am going to make a torque arm for it. It does wrap up a little. I wanted to keep the stock soft ride, so I didn't want to use any stiffer springs.
As far as the vibration from your rear end. Make sure you didn't pull your driveshaft apart after you got it back from the driveline shop. The u-joints need to be in phase. If they aren't, even a brand new driveline will rattle like crazy. Also remember, you can't turn up your rear axle unless you have a CV. If you don't have a CV, make sure the t-case flange and the axle flange are parallel to each other.
I can't remember how much we moved the axle forward, but quite a bit. It worked out perfect so that the tierod slips up into the oil pan notch when the suspension bottoms out. Any more forward and the tierod would hit.

overall that's a good lookin' job........nice and clean steering.

my main critisism would be that it looks way tall :eek: just seems like a ton of ride height (lift) for 35's......let's hope those springs sag a little.

or better yet, why not pull a leaf up front and lower it a little, add some bumpstops to limit the up travel and loose the lift blocks in the rear?

these trucks are pretty top heavy, so the height becomes a real issue.

Trevor

The pictures were taken before it was totally finished. We bump stopped all 4 corners and built some tube rock sliders. As far as top heavy, that is a concern to me as well. I wanted to go smaller with 33's, but the customer wouldn't go for that. It has sagged quite a bit since this picture. With the shocks turned up, it doesn't seem to lean much at all on the road. Oh well, it is only a matter of time until he puts it on its side! Trevor

You know there are ways of fitting big tires with less lift right? Other than the rather excessive height everything looks damn nice. Now we just need trail pics.

I'll keep an eye out for that rig to crawl under... looks good. I've pondered the double-arm with reversed tierod as a way to make room for steering in these Isuzus, but this is the first time, IIRC, that I have really seen it.

As others have said, it sure is tall, but the owner gets what the onwer wants, right? I bet he'll be asking for a lower ride if he realy does much 'wheeling in it, especially over Sierra boulders.

The front driveshaft has been a problem for many of us Isuzu SAS-ers, especially if the stock drivetrain is retained. It shortens the life of that U-joint, to be sure, but as long as the yokes don't meet, works OK.
Going to the Toyota flanges earned you some angularity potential that should help, but I still worry about driver-side stuff, passenger side droop, and uphill climbs where the springs aren't weighted and you maximize the dangle... you may want to have the owner keep an eye on the yoke ears for binding. Easy enough to fix with a limiting strap, if you need to. FWIW, Isuzu has tall-eared yokes, as well, generally on the rear driveshaft at the pinion. These take the same U-joint but offer much-increased angles of operation.

I also like that you just cut turned the alignment shoulder into the corresponding yokes. That's a more elegant solution, in my mind, than some of the alignment washers I have seen. I saw a clever alignment spacer in Moab last week that had the same basic result as both of these methods, with included studs and offset boltholes. Probably six of one, half dozen of the other, in the end, but I like your solution.

Nice work...

As far as the front driveline, the isuzu flanges wouldn't even come close to getting enough angle. They bound up at a few inches of droop. There is no need for limit straps with the Toyota flanges. All full flex and full droop it spins perfectly clear. I won't let any vehicles out of my shop without checking all drivlines for bind.
As far as CHICO State, I practically lived up at Butte meadows and the highlakes. I am also a Clamper. I would suggest anyone who likes the outdoors and hot drunk women to go to CHICO state. Trevor

That's me Mike. I never get a chance to make it to the doins'. Way too busy at the shop. You know how it is. I have a few guys I would like to bring through in September. Stop by my shop if you are in the Auburn area.

I saw this thing on the road the other day! Looks nice!

Is the owner on the boards? I think he needs an Isuzu wheeling buddy :)

Trevor
06-21-2004, 12:44 PM
He isn't on the board. He would really like to find someone to go wheelin with. He had me build the trooper, but hasn't really taken in out yet. I don't have the time to take him up to the rubicon, but I am sure he would like to meet up with someone else with a trooper. His e-mail is emailme@stribik.com. His name is Laz. Trevor
