Low Range 2WD
I will be picking up a new to me boat this week. I think it weighs in around 3000lbs. My driveway is a slight uphill grade. I always use 2wd Low Range when I back my utility trailer around. I have read in 4Wheeler magazine that using 2WD Low is a good way to snap an axle. I would like to use 2 Low to back in and pull up the boat ramp. Anyone see any problem with doing this if I'm easy on the gas?
Does anyone else do this?

Breaking axles in 4 Low can be easy if you get the truck in a position that places a lot of torque on the front axles . Backing , towing your boat shouldnt do that but then agian you really shouldnt need to use 4 Low . 4 High would be plenty for pulling the boat up a slick incline such as when you pull it out of the water , just to gain a little traction . On dry roads & the added weight towing your boat you should be able to back the boat up your driveway w/o using any 4x4 .

i had a '90 f250 with a manual tranny. i got along fine using 2-low as long as i took it easy on the gas. if i got my cattle trailer full and got too rowdy on the gas i'd tear motor and trans. mounts apart.

I think shotgun means using 4Lo with the front Hubs unlocked. I don't think it is easy on the transfer case to have the front unlocked but I don't see how any more than 50% of the power would go to the rear axle. If you take it easy on the RPM's...it would probably be ok.

Gentelman: I should have been more clear. I was refering to the unlocked front end and using low range for short slow speed manuvering and backing around obstacles when the grip of 4WD is not needed. I hate to slip the clutch. (One reason why I chose the manual transfer case/manual hubs) As far as the rear axle goes: Would the torque be much different than a ZF 5spd in granny low?
With any luck I'm off to the lake this weekend. I will report any catastophic failures.
Thanks for the replies, Chris

I do this all the time (X-fer case in 4-lo w/ hubs unlocked). Over 4 vehicles, I've never had a problem. It's a great way to get some extra low gearing for manuevering. Just be gentle on the throttle and you'll be fine.
