Some JEEP information.
Jeep does make non-4WD vehicles
And some 4WD jeeps (those with automatic transfer or full time 4wd) they say DO NOT TOW.. Most 4wd with MANUAL transfer can still be towed with Transfer in NEUTRAL and transmission in PARK of all gears.
Some modern jeeps have a problem with what we term "Death Wobble" I am not sure why this is since the only jeep I ever owned was older and only lasted 4 days (long story not the jeep's fault). This is where teh steering suddenly wobbles from side to side when towing.
I SUSPECT it is the Castor setting on the alignment. but as stated. I do not have a jeep any more.. Or a wife (Same accident).
