I just replaced my 2003 XLT 4x2 Limited Slip with a 2005 Adrenaline open differential and am wondering how reliable the 4wd system is on this model. I had next to no problems with my '03 in the 11 years I owned it since new and I'm hoping this 2005 will be the same. It runs great but I'm wondering if there is anything I should be aware of or keep and eye on. I didn't see much after searching on 4x4 and 4wd in 4x4 category.
