I want to switch out the t-case on my 1979 G-wagon for something lower than the stock 2:1. I have a gear driven divorce case with the 5:1 ratio that I want to throw under it. The problem is the reverse rotation in the front axle and t-case. I found out that they "think" that the carrier in the front axle is the same as the rear. Is it possible to take the rear straight cut R&P and install them in the front? I understand that the contact will be on the opposite side and it may be a little weaker but will it work. :confused:

Chaning out the front axle is a last resort, I would like to keep it MB as much as possible.

I dont think the carriers are swapable.
Have you thought of turning the front differentialcasing 180 degrees, you will get high pinion. But, count on some minor oiling issues, if its doable.

The carriers with the locker have the same part number. They appear to be the same size. The differnce is the front reverse cut gears is a 5.29 ratio (37-7 R&P) and the straight cut in the rear are 5.33 (48-9 R&P). So I am not sure if the bigger pinion from the rear is to large to fit the front. I was hoping someone has tried this.

Good luck. Is yours a diesel?

Mine is the 4cyl, I was sold on moving to the 5cyl Diesel until I started looking at the numbers. There is really no substantial gane on the trail with the swap. It is mostly a trail rig and on long hauls it is on the trailer.

Time to go with dual cases I guess.

I will check with them-

Thanks

You may be right. Did you compare to the turbo model or the NA? That might make a difference. Also don't just look at Horse Power. That is a poor indicator of advantage in a swap to diesel

Im very curious about thes gear driven divorced t-case with 5:1 ratio you are speaking of, where did it come frome?

Check out these pictures of a new 460 front and rear ring and pinion set, it looks to me that they should be interchangeable. Ive refurbished several 460 axles and know that the r/p carriers and bearings are the same from front to rear, but Ive never thought about swaping one for the other, I guess the deciding factor will be if the front housing has room for the slightly larger rear r/p.

I may be missing something, but it seems to me that if you put a rear r/p in the front housing, wont the front axle still be reverse rotation?

If I am remembering correctly the Reverse cut are actually "reverse cut". So in theory they should spin the opposite way with a straight cut gear. The next option is to install dual cases with new drive shafts which is starting to make alot of sense as well. If I install the new transfer case in front, run a short drive shaft between the new and the old the original in the rear will handle the problem of the reverse rotation. This should put me at almost 300:1 final ratio to the ground with both cases in low range.

The case is a gear driven top shift Toyota Case, the kit is from Inchworm. The cases are bullet proof although Inchworm has been less than helpful. They jerked me around for three months-they did not include parts-etc. etc. They include the 5:1 gears and the divorce adapter (by OTT) with the drive shaft flange.

I did look into the torque- horsepower does not mean alot to me. The torque was close enough that with custom headers and better exhaust it should be almost the same at low RPM's.

The transfer case on the 463s is full time. Just swap in a G500 axle, though you will limit your R&P choices.

So is the G500 axle changed from reverse to a straight rotation? My transfer case is a part time- not that it makes a difference. The R&P should still be the same as the 460.

As discussed on another forum (you know the one!), there are only a few R&P choices for the 463 series. I do not know what the highest is, a 4.8 or maybe 5.3. The 460 axle R&P are available up to the 6.17 because the 461 military axles use them and they are interchangable with the 460.
Good luck!

I may be completely wrong but my understanding of the G wagon is that they use a 2 shaft gear drive T/case that reverses the rotatation of the front driveshaft. The front differential is identical to the rear one but is simply turned upside down so that the front and rear wheels are driven in the same direction. Make sense?

No I don't know the one. I don't think anyone will mind if you mention it here. So spit it out. One of these days I'll find a new home for a couple of my Mogs and I'll get that G i've been dreaming of.

Bob,

280GE was referring to Benzworld.org (http://www.benzworld.org/forums/forums/forum-view.asp?setcookie=1&fid=30&DisplayType=threaded) and their G forum.

Happy surfing,

So why not flip the diff?

Well that does make some sense, the front is a high pinion set up while the rear is the low. The front t-case output actually does spin the opposite way that the input and the rear output shaft do. I want to keep the axles as close to stock. I did some measuring and fabbing this weekend and I will be able to squeeze in an addtional t-case so I don't have to screw with the rotation. The plus is the options of the gears will be much greater.
