Just read a bit on Lextreme. Apparently the Crown 1uz has a more compact (but more restrictive) exhaust system.

I also ran across this guy who used a remote oil filter and did some mods to the oil pan too:

Maybe you have seen that allready, but thought I'd post it.

Also Isuzu used a rear disc Dana 44 on the back of 90's Rodeo's, Same six lug pattern. This is what I will go with WHEN I dump my next set of Toyota R&P. Maybe these will last.

I'm gonna hunt one of these Isuzu's down for giggles, they can't be much at the bone yard.

I supposedly have the more compact "log" type - believe me, they aren't compact.... Obviously designed to fit the low, wide engine bay of the LS400 and similar.

Headers and a full dual exhaust should do the lion's share of upping the HP numbers. Remember, the JDM engines generally have understated HP figures. Although not right away, I have considered forced induction in the future if this powertrain isn't "ballsy" enough.

I have flange drawings and can get them cut out at any time - also found a place with inexpensive mandrel bends. Motor mounts first, headers second, oilpan mods third.

Cebby

I appreciate you posting up that link. I've gone over that site before, but I have so damn many bookmarks, stuff gets lost in plain sight...

Cebby

I'd be curious to see what the width of those are - seems they'd be a good bit narrower than the GW 44's. Wonder if the rear discs would bolt up to the GW 44 from the Isuzu??

justinh

Do they use the standard 44 R&P? For some reason I seem to remember you had to get creative with the R&P and carriers on those, but that may have been the older 10 bolt rearends.

I know you post there some but a guy on Nissan4wheelers swapped one in to his pathfinder probably 4 years ago when he SAS'd and I think there is another guy that posts as Rondo that has one in the back of his Frontier too. There is probably a good bit of information over there buried regarding those axles if you need any more info.

justinh

IIRC, they are going to be around 59" WMS. If you really need the measurements I can try and get them for you. My sister has a 2wd 2001 Rodeo, while I am not sure if it is the Dana 44 it is probably going to be the same width.

sschaefer3

Grand Wagoneer is 61" WMS to WMS front and 58" WMS to WMS rear. 6 bolt Toyota pattern with SAE studs, which can be changed to Metric Studs.

I'll have to check out the Isuzu, but from what I heard and what Cheese (The Ultimate 4X Web Search Engine) has seen, the center is pure Dana 44. Don't have a clue on the Isuzu width.

3rd Gen 4Runner rear axle is 60.5 WMS to WMS

OK, Here is more Updated info. I am suppoed to go look at/buy one of these today. We'll see if they come through.

So far from what I found is that there are a TON of these in yards already. Also first thing out of every Junkers mouth is $500-750. All you have to do is mention that EVERYONE else is selling them for i/2 to 1/3 of that. They know it and magicly the price comes down. This is not a TOYOTA axle, there is not a demand, the high prices are for Insurance Companies apparently. I even found some in the Midwest for 100 bucks. A rear Dana 44 with disc brakes. I still have to verify the 60" WMS to WMS. I may just look and not buy if they raped too much off of it. Best I can do in Phoenix is $250 WITH calipers. We'll see, I can pass on it as I don't NEED it. Evenif it's good I'll offer 200, they have many of these in the yards, no shortage.

Here is the "correct" info I have collected from the Junkers:

Isuzu Rodeo/Honda Passport 91-97 (R) Dana 44 58" (SUA Leaf) Value in Class 4/10

Isuzu Rodeo/Honda Passport 98-04 (R) Dana 44 60.5" (4-link, ABS, 4.10 & 4.30 Ratio) Value in Class 3/10

1990-1995 4Runner: value in class 5/10
1996-2002 4Runner: value in class 5/10


1998-2004 Isuzu Rodeo/Honda Passport Rear Dana 44:

4x2 (drum brakes), 4.56 ratio (41/9 teeth, HC6)
4x2 (drum brakes), 3.73 ratio (41/11 teeth, 6NW)
4x2 (drum brakes), 4.10 ratio (41/10 teeth, GT5)
4x2 (drum brakes), 4.78 ratio (43/9 teeth, S2J)
4x2 (drum brakes), 4.30 ratio (43/10 teeth, S7C)
4x4 (disc brakes), 4.10 ratio (41/10 teeth, GT5)
4x4 (disc brakes), 4.30 ratio (43/10 teeth, S7C)



1999 Isuzu RODEO Recall ID from NHTSA: 00V058000
Auto Recall Date: 03/02/2000
Vehicle Component: SUSPENSION:REAR
Estimated Vehicles Affected: 213736
1999 ISUZU RODEO Defect Summary:
VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES. PAINT WAS APPLIED UNEVENLY ON THE REAR AXLES, RESULTING IN INSUFFICIENT PAINT HARDNESS. SHOULD THIS OCCUR ON THE SURFACE THAT CONTACTS THE REAR AXLE LOWER LINK BRACKET BOLT HEAD AND/OR NUT, THE NUT MAY LOOSEN.
Defect Consequence:
THE BOLT COULD DETACH FULLY, CAUSING SEPARATION OF THE LOWER LINK FROM THE REAR AXLE, INCREASING THE RISK OF LOSS OF VEHICLE CONTROL.
Remedy:
DEALERS WILL REPLACE THE REAR AXLE LOWER LINK JOINT NUT AND BOLT.
Notes: ISUZU MOTORS LIMITED,


I'm cutting the link stuff off, but hey tell the junker about how the axle was never fixed under this re-call. They won't know. Junkers will take all your money if you let them.

I have to verify that a 1985-1991 Jeep Grand Wagoneer Dana 44 will be a perfect match. I'm off to measure the Isuzu axle.

bamachem

no, but it's way cool on the pucker factor from the passenger seat!





this is what steve meant by how it almost "squats" when you cross up the front/rear...





oh, and how does it drive? better than my tundra setup! seriously. i like the feel of the SUA leafs than my best-thing-out-there coil setup. it's good on the road and on the gravel and when crawling. it's a shame that leafs aren't an OEM option...


more pics of the SUA 4-cyl-of-fury



looking good cebby!


so, a GW 60.5" front D44 from the late 80's and a 97-99 Rodeo rear and you could have SUA front/rear 44's with 4-wheel disc. hmmmm. now if there were a way to keep the ABS on the front... maybe FZJ80 outers?

sschaefer3

That bottom pic is living proof that the the spring under the axle are indeed rock ski's.

Sprung over the tube in this case would have cought. Now it you would have had 40" tires, it would not have.

It's all about thinking and what will work best for YOU.

justinh

Good info, Andy (Desertrat) is a good guy, he was one of the innovators back in the day with the Frontiers, I can remember when I first got my Pathfinder back 6 years ago and he was just starting with that truck, his truck followed a very similar build to yours and the two of you have ended with very similar results.

Bighead

Awesome work Cebby. I was reading the updates in your PBB thread last night and continue to be impressed with the work.

I agree. Steve's 4Runner is a nice ride. If I didn't have all the computer stuff on my '01 I would be working my way towards this type of staright axle setup. As it is now, my 4Runner won't have anything but IFS because of the electronics.

sschaefer3

Never say never, if someone gets these big axle building companies to make a front axle for the FJ Crusier, it will have all the senders, etc that you need.

Sit tight. Ok enough of this, back to the motor. Cut the IFS crap out of the way.

Cebby

Check out the fit on Mudman's headers (see pics up above - with blue background)

He did some nice work on fitting those in amongst all of the IFS and tight 2nd Gen engine bay (pics by Mudman from Lextreme):










Mine will be slightly different, since my motor will sit a bit lower in the frame than Mudman's...

sschaefer3

Here's an Idea. Make it a 2WD truck until you SA it. I just think jumping through all those hoops for "that" IFS is crazy. If you had the 3rd Gen 4Runner IFS I could see it.

Pull the diff and axles and run it with open spindles. You know you'll swap it soon anyway. After it runs again.

deathrunner

Seriously, dude. Axe that 7.5

I worry enough bout mine with a beat ass 22RE. How do you even expect to use IFS 4x4 with that monster mill? I hope you're running 215/75/R15's hahaha

Otherwise looks cool. I'm interested to see how your headers come out.

sschaefer3

I have collected a TON of Isuzu Dana 44 data and have updated and will continue to update post 488.

Corvettes ran IRS Dana 44's so I think this may be strong enough for you.

Update, late 5-10-2006 Looks like I bought an Isuzu Axle. I was going to blow it off, but one of the places I called yesterday called and said it was on the truck to be delivered, so I said OK. WTF.

We'll see what a dual disc Dana 44 looks like. Tomorrow I go to Tellico though.

Update, Evening: It's here, one beefy mother. Certainly a Dana 44 no doubt about that. I got a great deal, hub to hub complete with brakes, calipers, rotors, links, trac bar, brake lines, etc.

Bad news is it's 63". So I'm willing to be the 91-97 drum unit is 61" those are a dine a dozen, I can measure one in a U-Pull it.

This axle is quite impressive. It will work perfect on the 4Runner if I dump another set of 5.29's. I'll have to run 4.5" BS rear rims. With the 3.5 up front on the 61" Waggy, it will be fine. Buggy Axle ???

Pics when I get back from Tellico.

nfenwick

Cebby, you have done a great amount of work and I learned a load of info just in what you have done in this thread. I have a 3rd gen and am very interested in how this swap goes. I would like to do the same thing to mine. Although I will still be retaining my A/T and IFS. I have no interest in rock crawling so I will be watching to see how this goes.

Churnd

Ceebs, what's the status on the swap? It's been over a month and nary a post...

Cebby

Been over a month and I've been to the shop only once and that was to take some dimensions of the rear driveshaft for someone.

Too busy with other stuff currently. I forget what color my 4Runner is....
