My brother got infiniti qx4 and it rattles on high speed?
Hi there, my brother have an infinit qx4 1998 truck and has 112miles on it. he is been using it for the last 4 years and never changed the tranny oil. his problem is that when he is driving the truck on 4wd option (auto mode), when it reaches 50-70 mph, it kind of rattles and you can feel little shakes on your steering wheel and gas pedal, kind a like buzzing and when he stops the car and it is still in 4wd, he can hear little noice and as soon as he put it to 2wd, the noice goes away. plz tell me whats going on, weather his tranny is having a problem and how can we fix it. thanks in advance.
Answer
Yeah he is gonna have a crap load of problems since he has it in 4wd, 4wd is for offroad use not driving 50-70 thats just common sense. its shaking because its not supposed to be in 4wd at that speed and his transmission makes that noise in 2wd because he messed up ething driving in 4wd
