Here's how my twisted mind reached this point....After reading the rest of the thread on G-wagen side slope capabilities, I thought, "Gee, so I probably shouldn't try the test track at the LR center." Then I thought, "Oh, they'd never let you do it anyway." Then I thought, "Maybe at night?" Then I remembered, "No, they park a disco in both ends of the track every night so you can't get on it." Then I remembered, "You only need to lift a front and a rear wheel to move a Disco..." Which lead me to think of the most secure way to leave a Gwagen parked.....Lock the front and rear diff locks, put it in 4wd, and apply the parking brake. That way you have to lift ALL of the wheels to move the vehicle. A tow truck/dolly lifting up one end or the other won't do it....-Dave G.PS- another interesting thing I discovered during my drive shaft R&R. Putting the t-case in neutral disconnects the drive shafts from the transmission, but it does NOT disconnect the shafts from each other. You can't flat-tow a G with the t-case in neutral....

dear dave be careful when towing with transfer case in neutral as the internal oil pump is not driven when the main gearbox shaft is not turning.

re: "...be careful when towing with transfer case in neutral as the internal oil pump is not driven when the main gearbox shaft is not turning..."Interesting comment -- can you elaborate? The Transfer Case doesn't have a pump, does it? Is this instead referring to the automatic transmission's rear fluid pump? If so, then why is there any concern -- if the main gearbox shaft (i.e., between transfer case and transmission) isn't turning, the automatic transmission is at rest (assuming the engine is not running, of course). Or have I confused some components? Thanks very much.

re: "...Lock the front and rear diff locks, put it in 4wd, and apply the parking brake. That way you have to lift ALL of the wheels to move the vehicle. A tow truck/dolly lifting up one end or the other won't do it...."The only problem is that none of these "settings" are really secure. Anyone can jimmy open a door (or break a window) more easily than putting it on a flatbed towtruck, and once the door is open, they can push down the locker plungers, take off the parking brake, and (if you've got an automatic) put it in neutral -- the "Park" position isn't even linked to the ignition switch, as it is in most contemporary cars. We (who have automatics, at least) need a way to lock the shift lever in park -- I've seen, in catalogs, steel "shift gate" plates that have a keyed lock, but these are all customized to the car shift gates! Our G's have a different gate, and it won't fit.

My point was that you CAN'T tow the G with the T-box in neutral, no matter what kind of trans you have. This is because with the G t-box in neutral, the truck is in 4wd, with the front and rear drive shafts locked together. If you try to tow it this way, you'll end up with drive line wind-up very quickly.You could tow a manual trans G with the t-box in "S" (2wd) and the tranny in neutral, but the fact is it's just not that difficult to pull a drive shaft and remove all possibility of trouble. (granted, VERY slim possibility of trouble doing it as described).Now if you have an auto box, then you REALLY should pull the drive shafts (at leat the rear one with t-box in "S"). Automatics depend on input shaft spinnning to pump lube to the nether regions of the box. But, I have a manual, and everyone will do their own thing anyway, so.....I don't talk this subject much anymore.... :^)

Thanks, Dave, but you didn't answer my question. I agree with you about the towing precautions you mentioned, but I wasn't asking about those. I'm asking about the internal oil pump that you referred to ("...be careful when towing with transfer case in neutral as the internal oil pump is not driven when...."). What and where is this pump? You have a manual transmission, but were you referring to the pump in an automatic? Or what? If there's some oil pump that I don't know about, I want to learn!!! Again, thanks.

Dear Ken C I was the one who told you about the oil pump in the transfer case.Yes it does have an oil pump it is built into the casing of the transfer case and pumps gear oil to bearings and shafts in the box hope this explains.This is why you can only tow certain distances and speeds without doing any damage to the transfer case.

Thanks for the info -- I had *NO* idea that the transfer case actually had a pump! I just thought that it was like a manual transmission -- i.e., merely filled with oil and the spinning gears' teeth splashed the lubricant all over the insides of the case, lubricating the parts by the oily downpour! Thanks for the heads-up. BTW, anything we should know about checking the pump to see if it's working properly? ...to prevent premature failure of the transfer case?
