Re: Flat towing \'94 YJ
Here's my take on it. The tcase bearings don't get lubricated when flat towing. I know a guy who has towed his wrangler to Montana from San Diego and back several times with no apparent problem.
If it were me, I wouldn't like the extra risk....especially with someone else paying attention to the little things.
Hey, since they are borrowing your Jeep maybe you have them spot for the full floater kit with lockout hubs. That way you have no risk......well, no risk if you don't have a locker up front. If you have a locker up front, you should really have lockout hubs up there for flat towing for the same reason.
One other thing...If they are driving all the way across the country and then staying in one place where they would use the Jeep, unhooking the drive shafts isn't hard. But, if they are driving and stopping every day that is going to get old.
And finally, if you haven't put a slip yoke eliminator on the rear output, you really can't pull the rear drive shaft and drive in front wheel drive without losing most of your tcase fluid out the slip yoke. I once had to drive 30 miles without the rear shaft (limping out of a trail) and I tried to rig up a cover for the fluid, but I still lost a quart or two.
Hope that helps.
