ok stupid question, why would a manufactor build a 4wd and design it to not be used in 4wd on dry pavement? i dont understand where your coming from on that, i didnt mean the axles would break first(i said give) i meant they will allow the transfer case to be locked while they give (slip,go faster or slower) around a curve. if the transfer case does lock when you put it in 4wd then the frt and rear driveshafts will turn at the same speed at the same time. i understand that. but that would make the frt and rear diffs do the work of spinning faster or slower when going around a curve( the job of spider gears to move and let the outside tire go faster and the inside tire to go slower)i do have the tru-tracs frt and rear, but like any locker they will give(unlock) when going around a curve, but i do know when you add bigger tires and a lift and lockers you will find your weakest links. but i dont see putting it in 4wd on dry pavement and breaking the transfer case apart. after i took everything apart i looked at the case, it had a lot of stress cracks in it and the part for the frt driveshaft was broke off completely(the chain was the only thing holding it all together) i looked at the slip yoke on the driveshaft (factory without grease fitting) and had to take a hammer to move it so that is the only thing i can see that would break the transfer case as it was, and when it goes back together i will drill and install a grease fitting, but i grease every grease fitting about everytime i get back from 4-wheeling and i have tried to spray stuff in that yoke but it didnt work, usually i go play on the weekend, take it to work on monday, after work put it on my lift at the shop and start greaseing it and cleaning the brakes
