CUCV for both front and rear axles

[Jasondavid]

I found a complete chassis on Facebook of a CUCV with both axles. I've read the entire thread on replacement axles and searched the forum for quite a while but couldn't find a definitive answer to the following question...

If I were to buy this frame and suspension would it be a sensible replacement of (just the axles) both the front and rear axles on the Kaiser? I would love to not have to replace motor and other parts right now. Hoping I can change axles and still use the transfer case, transmission, .... Until I'm ready to do a complete rebuild. .... Or do people run into a lot of trouble with that axles in terms of parts, fit, frustration getting installed

I used a front chevy Dana 60 and a Dodge dana 70 for the rear. It is just a matter of seeing what and how you want to get it done. It was not hard in my opinion. I just started with the modifications knowing what I needed to do and finished each stage. I like the end result very much. I used the front by cutting off the frame spring mounts and elected to use the longer chevy springs on the OEM locations on the housing. So I had to weld on spring perches under the frame on the rear and up front. It caused some alignment issues since the chevy frame drops back into a workable area after passing over the axle going forward. The M715 frame does not drop much and I had to use double steel wedges on each side the spring packs to keep some decent alignment specs. I do like the longer springs as they will flex better. I will be using mine off road. The M715 springs are so short they just can't flex like a longer spring. You also could relocate the spring perches on the housing and keep the original spring packs. That would probably be easiest. Just watch your alignment specifications. The rear dana 70 was just a matter of welding on new perches to use the OEM springs. I also took my rear springs off and cleaned them and coated the friction surfaces with slip plate number 1. It makes it ride 1000 times better and only gets better with use. As for parts, you can find them all day long and the aftermarket support for them is vast. They have much bigger shafts that the m715 axles and in my opinion are true 1 ton axles. If the rear is a 14 bolt. The shafts as far as I know only come in a 30 spline configuration. The advantage is much more parts availability. So that is a win. The m715 has only larger ring and pinions. The shafts left something to be desired in my eyes. Sounds like a good find. Make a plan and enjoy it in the end. They are in my opinion better axles. And welcome aboard. Stick around and keep us posted.

Make sure it is not a M1009 with the 6 lug 10 bolt front and rear axles.

However, the M1008, M1010, M1028. M1028A1 and M1031 6.2/TH400/NP208 or NP205 with the 4.56 geared full float rear axles and open knuckle front axle are probably the best combined package you can buy to swap into a M715. The result will be great on road drivability that with 38 inch tires will cruise 50-60 mph all day long. Then with the 6.2 low end torque and the gearing be really capable off road.

Thank you!
This one says it's an m1028. How can I confirm if?

Hard to tell from his fast video and the pictures. The front bearing hubs where the locking hub is look small for a dana 60. I could be wrong though. All dana axles usually have the size cast into the web between the tube and diff casting. Usually a lower web. The big size of a dana 60 is pretty hard to miss. But pictures are difficult to see.

A stock M1028 axle will have a Detroit locker in the rear.

I'm probably too late on this, but I saw the price, said to myself wow that is cheap, then looked at the description. The frame is from a M1028, but the axles are from a a 1/2 ton. You definitely do not want those under your truck. The pics clearly shoe that they're 6 lug.

Thank you for that confirmation Bill. I saw the front bearing hubs and thought they were not the bigger size and not tapered as a dana 60 hub would be. Shameful to be selling something branded as one thing when it is another.
