[QUOTE="Yardsale , post: 1026080, member: 58988"] :offtopic: Not a solution regarding the thump, but the tires being (about) the same wear (diameter) is only a concern with limited slip differentials and when using a locked type transfer case 4WD on a surface where the tires cannot slip, which should not be done with this type (locked) transfer case. If using the 4WD as designed, this should not be an issue. Mixed terrain (like the snow with intermittent street, that you note) can cause problems, though. In the case of limited slip, there are clutch plates that wear when the two half axles turn a different rates. This is not the case with an open differential, as with the front. Also not a problem front to rear with the 4WD not engaged because the front drive is not powered. :back2topic: [/QUOTE]
