Me and a friend of mine got chatting and decided we should build his old 95 ctd in to a 4 wheeler.
We want to run the biggest boggers we can buy. (I think 48)
He needs a new clutch anyway, so we will install a southbend. We will probably swap the gears out, the rear diff already has an air locker in it.
My question is will the stock drive line hold up to the big tires and abuse?
does anybody know of anyone who has built a truck up like this to take out to the mud to beat on?

 

I think the rear axle will be ok, but I'd be worried about the front D60. I'm guessing it has the CAD on it, which isn't the most reliable. Also the factory unit bearings wont be to happy. I'd upgrade to a Dynatrac or EMS Offroad kit to convert the unit bearings over to the hub/spindle type and eliminate the CAD at the same time. The ideal setup would probably be a D60 out of an old ford that has the kingpin knuckles. Either that or a pair of Rockwells

The rest of the drivetrain should be ok. Only other thing I could see upgrading is maybe the driveshafts and ujoints, and maybe the front control arms (stock ones are just barely enough from the factory).

I'm sure theres some video's floating around on Youtube of a Jeep with a 5.9 cummins in it. I think its got a stack out through the hood, don't know what he used chassis wise, but I've seen it in a couple magazines now. Looks like he does mostly trail running with it.

 

biggest boggers are 52's

 

they're actually 54".........


these are 54" boggers, a friend is getting aquainted with one

 

OOOhhhhhh DOOD!!!

What happens between a man and his rubber should at least stay between them.

No doubt that is a late night wrench session. Been through a few of those moments for sure. Cool tires.

Should I assume that both of you guys are HD techs. The humour seems to fit.

Nice truck, be cool to see the finished product.

 

Even if you just went with the regular old 44" Boggers, you would still be breaking front axles all the time. I know D60s are strong but 44s and Cummins torque is more then they can handle.

If it were mine, I would put a set of Rockwells under it and be done.

 

omg thats halirous

 

I second that - Rockwells will end your problems. Too many wheel bearing problems with stock, and the kit to upgrade is not cheap, either.

 

i busted up my front 60 with just a smallblock 408 and 44s you will definatly need a set of rockwells.

 

depending on what youre doing with this truck, even rockwells might break. you may have to look at the 2" stuff... 5-ton stuff might be the best choice, at least the best bang for the buck. remember, youre already working with a 8000 pound truck BEFORE adding the heavier axles and wheel/tires.

i would also look into changing out your transfer case to a 205 or even a 200 depending on how high this truck is going to sit.
