i have a 96 toyota 4runner with the 3.4l. first has anyone had a problem where they were unable to open the rear hatch. the handle will stick in the open position but the hatch won't come open then it is extremely hard to get the handle to go back foward. so i am unable to open my rear hatch, however the glass still goes down. also how durable is the transfer case. i race my truck almost weekly and occasionally i run it in 4wd so i can get it to hook up. should i be worried about ruining my transfer case? also i see some people are running nos on their trucks, how is that done?
