I added the warn 424 to my 99 foremanS and it works great. It shifts easily from 2wd to 4wd and does exactly like it is suppose to. My question is, is it normal in 2wd mode to occasionally hear the front differential turning free while riding? In 4wd there is no noise from the differential, but occasionally while in 2wd I can hear the front differential. It's not loud and doesn't seem to be engaging, but didn't know if this was normal because I haven't ridden with anyone that has one. I've put about 15 miles on it and haven't noticed any problems other than the occasional rattle, usually when slowing down. I've checked the front differential oil and it has enough oil in it, and the oil looks fine. Just want to make sure that everythings alright before I go on any long trail rides out of state. Thanks for your help.
