you could just use the inside wheels,I was gonna use a no-offset wheel thatwould center the tire better
Ideal is to track the rear with the front

 

rbaker 6336, I don't know where you get your information but in the snow my dually works great. Any thing on ice is bad. In the sand your right but, I have friends that went to 315 tires with spacers and they track on top just fine with there crewcabs. No kinding. If I didn't see it I wouldn't of believed it. Mine is LSD 4:10 Its a matter of choice but on the highway I think the dually lsd works safer then the srw as long as it is snow not ice. In the mountains on hunting trips with a unloaded horse trailer I just pull out in the bush to turn around and never got stuck yet. Good luck guys this is just my personal experience not to put down any body elses experiences I know they mit be difference. Chet

 

Well I kinda got my information from 50 years of driving experience

 

I second that with 46 years

 

Just curious but it seems we have pretty much the same truck and I'm just wondering what kind of fuel milage you get? I average about 13 mpg. How I drive it does'nt seem to affect it much.

 

.....UPDATE.....
Well, it has been quite an ordeal with this rear diff. I don't have the facility to work on it so I took it to a trusted friend who does. I ordered the Eaton Tru-Trac and it came quite quickly. $1130 CAD. It don't fit!!! After nearly 12 hours of working and swearing and trying to shim it properly, we discover that there is no amount of shims that will make it work. If you shim it over where it seats properly, you cannot set the backlash properly. After many hours and much cussing we pop it out and take it back.
We contact Eaton and they cannot tell us why it won't fit. The parts place is well schooled in diffs and they say they have never sold a Tru-Trac in 3.73 ratio before. Eaton says that they don't even have another one to look at to see if it was mis machined.
The whole problem is...the 3.73 ratio is so rare in these trucks and Dana eighty, that they haven't had this problem before. Eaton is investigating and will get back to me when they find out, if ever.
My advise at this time is...if you have a Dana 80/3.73ratio rear diff, don't try to put a Tru Trac in it.
I will relay more as it unfolds. For now, back to the one wheel peel after two weeks with no truck.
Of course the Holidays did not help as everyone was closed.
