I have a question for someone more mechanically inclined than me. I have been lucky so far as to not have had any major mechanical problems on the trail. Broken U joints, split hoses and a thrown belt has been the extent I have had to deal with so far. Anyway what I worry about most is a fried diff or half shaft (Until I change to a Detroit Locker/Truetrac and 24 spline that is).
My question is if I lose a diff or half shaft, what if anything can be done to limp home safely short of a field replacement. Any advise would be appreciated.
Thanx

| Hey Gene, What vehicle do you have? Year and make... |
|
I'm going to start thinking Positive!
But I doubt it will work.... |

I'm assuming you have a 10 spline rangie since you mentioned upgrading to 24 spline.
If you break an axle you can remove the axle in the field, and fish any bits out of the axle housing, then just drive home. The axle is used to turn the wheel, but isn't necessary to keep the wheel on the truck.
If you break a U-joint, just remove the driveshaft and drive home using the front/rear wheels only.

... If you don't have a Borg Warner T-Case.... What year is the rangie? Does it have CDL?

I know for certain that DII's with grenaded CV joints and/or broken front axles will drive home just fine in RWD after pulling the front d-shaft and running with the CDL engaged. In fact, you can go several months without problem :)
Your DII is not nearly as likely to blow the diff as it's a bit stronger than D1/RRC diffs. They upgraded these for the DII to compensate for the stress of the ETC system. Craig may be having a different experience as of late; not sure what the latest diagnosis was but I always look for broken axles and ujoints on the propshafts before blaming the diff or transfer case on these trucks.
fwiw |

"... If you don't have a Borg Warner T-Case.... What year is the rangie? Does it have CDL?"
depends on the distance ... you can get around on one propshaft with the magic soup diff. it just might freeze up in permanent CDL if you go very long with it that way. getting down to a trail-head or parking lot a couple miles down to somewhere more convenient to tow from won't really hurt anything. |

Ike,
My rear diff is out of Dan's D90. We put my DII rear diff w/ ARB locker in his 90 when I was looking to sell my truck. We put one of the new ARB RD128 lockers in last week and it didn't fix the problem. When were were in there, the ring and pinion as well as the half shafts looked good so I'm now off looking elsewhere.
The original diagnosis was done on a lift at Biggs. It definitely sounded like the noise was coming from the rear diff. Since I don't think that is the case any longer, I'm now going to pull the rear driveshaft and see what happens. The rear u-joint was loose, but I couldn't feel any lateral movement. When we were putting the driveshaft back on I noticed a bunch of fresh grease had squirted out of the rear u-joint closest to the diff. When I inspected it just a week or so ago, I removed a bunch of old grease and relubed it. That fresh grease all seemed to have squirted out for some reason... I'm suspecting the u-joint now, just haven't had a chance to pull it and look. The truck is in the driveway for now. |

Wow. I didn't know that. It is also news that the diffs in the DII are a bit more beefy! Maybe I'll hold off on my locker purchase. I'm happy with my trucks ability, I wanted to upgrade mostly for the durability factory. Good news.
