I have a 1999 Ram 3500 4X4 Diesel if i install a towbar on the front is it ok to tow this vehicle??

 

I have not seen any tow bars that are rated for above 5,000 lbs. Your truck is probably pushing 8,000. If you get past that I'm not sure if you need to pull the drive shafts or just put everything (tranny, Transfer case) in N. Also you going to need one heck of a truck to pull it with for it not to push it all over the road.

 

A local well company here flat tows there f350's and 450's behind their drill rigs with some heavy duty pintle style tow bars. Dunno if they drop the driveshafts or not but I doubt they do. But when my dad and I brought back my first truck from NC to WI we rented a uhaul dolly and dropped the rear driveshaft.

 

I move plow trucks around with a heavy tow bar I built that slides in the plow mount, it is good for moving the trucks around without having to tow a trailer or have a helper, hell I tow my 3500 with a Mitsubishi-Fuso cabover, whatever you do make it strong, my bar is made from 3x3x½" angle iron with a pintle hitch.

 

if you get the right bar yes, but pull the drive shafts if your going more than 10 miles as the trans will not oil right overheat and cause all kinds of issues. It's much better to be safe than to have to replace a trans. For the rear pull it out of the rear end duct tape the u-joint on and tie it up under the truck as to not leak tranny fluid out the tailshaft if you have an auto..

 

On a 4x4 I think you can leave the transmission in park and put the transfer case in neutral. This will run the pump in the transfer case and stop any moving parts in the transmission. Check for sure but I think that's right. A tow bar out of 2 inch tubing ought to be heavy enough.

 

I know when I had a jeep and flat towed behind my motorhome I always put the transfer case in neutral and trans. in park. As said above This will run the pump in the transfer case and stop any moving parts in the transmission.

 

I always just put the transfer case in neutral, never had a problem, as long as the rear driveshaft is spinning it is pumping fluid through the case
