I just install a 4wd shifter bracket last night to correct my issues with going into 4lo. I put a 4" Rough Country lift on about 3 months ago and I couldn't get into 4lo so I had to install this shifter kit. After I put this kit on I'm gettin a strange knocking shound from around my transmission/transfer case. The sound only happens for about 3 seconds when I take off in 1st gear. If I put my jeep in 4hi I don't hear this sound. The knocking sound is not very loud but I can hear it. I was wondering if anyone might know what causes this and how I can fix it.
