leaving my muddy yard in 2 wheel drive in my 92 jeep cherokee 5 speed manual tranny,i spun the tires for about 5 feet. i looked at the tracks,and both tires left spin marks at the same time. stock gears and axles. I thought in an open diff,only the tire with the least traction would spin? if this is the case,why were both tires spinning? thanks for any input!!
